Full Text Available En réaction à la publication de la suite apocryphe de Don Quichotte de la Manche, Cervantès utilise dans sa seconde partie les ressorts narratifs de la stéréotypie littéraire pour montrer à quel point son personnage diffère de ce qu'en a fait Alonso Fernández de Avellaneda, continuateur peu respectueux de sa personne et de son personnage. Le refus de voir en don Quichotte un simple stéréotype du chevalier errant chimérique est particulièrement manifeste dans la série d'aventures se déroulant au château des ducs, où don Quichotte, par sa renommée littéraire littéralement reconnue, est traité en chevalier par des personnages manipulateurs de situations, qui visent à produire chez lui des réactions programmées pour s’en amuser. Il apparaît alors que le simple agrégat d'ingrédients propres au stéréotype littéraire chevaleresque finit par ne pas produire l'issue escomptée.En la Segunda parte del Quijote, Cervantes reacciona ante la publicación de la de Alonso Fernández de Avellaneda, continuador poco respetuoso con la persona del autor primigenio y su personaje. Recurriendo a los procedimientos narrativos de la estereotipia literaria deja bien claro qué diferente resulta ser el personaje original respecto al del continuador. La negativa de ver a don Quijote como un mero estereotipo del caballero andante loco se pone particularmente de manifiesto en la serie de aventuras que transcurren en el palacio de los duques. Allí, los personajes reconocen literalmente la fama literaria de don Quijote. Generan, desde situaciones ficticias, tipos de tratamiento que se dispensarían a un verdadero caballero andante. Como resultado, se desencadena una serie de reacciones programadas con las que pretenden divertirse. Sin embargo, queda claro que la mera acumulación de ingredientes propios del estereotipo literario caballeresco no produce el resultado esperado.

Mycotoxins are toxic metabolites produced by fungi. To mitigate mycotoxins in food or feed, biotransformation is an emerging technology in which microorganisms degrade toxins into non-toxic metabolites. To monitor deoxynivalenol (DON) biotransformation, analytical tools such as ELISA and liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) are typically used. However, these techniques do not give a decisive answer about the remaining toxicity of possible biotransformation products. Hence, a bioassay using Lemna minor L. was developed. A dose-response analysis revealed significant inhibition in the growth of L. minor exposed to DON concentrations of 0.25 mg/L and higher. Concentrations above 1 mg/L were lethal for the plant. This bioassay is far more sensitive than previously described systems. The bioassay was implemented to screen microbial enrichment cultures, originating from rumen fluid, soil, digestate and activated sludge, on their biotransformation and detoxification capability of DON. The enrichment cultures originating from soil and activated sludge were capable of detoxifying and degrading 5 and 50 mg/L DON. In addition, the metabolites 3-epi-DON and the epimer of de-epoxy-DON (3-epi-DOM-1) were found as biotransformation products of both consortia. Our work provides a new valuable tool to screen microbial cultures for their detoxification capacity.

Full Text Available In this article the author compares the exemplo of Don Yllán and the Deán de Santiago -no. 11 in Don Juan Manuel's Conde Lucanor (ca. 1335- with an earlier Hebrew analogue found in the Hebrew Mešal Haqadmonī (ca. 1285 of fellow Castilian author Isaac ibn Sahula. A thorough analysis of the rhetorical and narrative style of both versions reveals that the two tales shared a common source in Castilian oral tradition. The appearance of the tale in an earlier Hebrew text from Castile (the only other known version in any language calls into question the originality of Don Juan Manuel's most famous exemplo, suggesting a productive interplay between a common oral tradition in Castilian and coexisting literary traditions in Hebrew and Castilian.

Frank, Nathaniel

2013-01-01

This study assesses the role of LGBT advocates in repealing the military's Don't Ask, Don't Tell policy in the U.S. Congress. It draws on the author's direct involvement with that effort as well as personal interviews and media evidence to consider the contributions of the Obama Administration, members of Congress, the media, and individuals and pressure groups in the repeal process. It argues that repeal succeeded not because of the effective implementation of a White House plan but because the pressure of LGBT advocates ultimately shattered several key obstacles including inadequate messaging and dysfunction and inertia among both politicians and interest groups in Washington. The article offers insight into the role of public pressure in forwarding social change.

Mimesis in Don Quixote

Giselle von der Walde

2006-04-01

Full Text Available Resumen:Frente a argumentos tomados de las poéticas neoaristotélicas que esgrime el canónigo para condenar los libros de caballerías, don Quijote pretende mostrar con su propio ejemplo, que ese tipo de lecturas no llevan a la locura ni al abandono de sí mismo, sino que, por el contrario, sacan lo mejor de la naturaleza de un individuo y lo hacen mejor persona. Este es el único tipo de imitación que Platón acepta en la República, pues más que un remedo o una suplantación, implica emulación. Este escrito se propone mirar, a partir del diálogo con el canónigo de Toledo (I, 49-50, cómo en sus conductas miméticas desde el comienzo de la obra, don Quijote entiende la imitación como emulación; en consecuencia se intenta demostrar que el efecto de la literatura en el caballero manchego parece ser el tipo de mimesis que Platón acepta en el libro III de la República.Abstract:Don Quijote demonstrates with the example of his own life the error made by the Canon of Toledo when the latter uses the arguments of the neo-Aristotelian poets to condemn the novels of chivalric romance. Quijote tries to show that reading the chivalric romances leads to neither madness nor the abandonment of the self, but, on the contrary, brings out the best in a person’s nature, and makes one a better person. This is the only type of imitation that Plato accepts in the Republic, because, unlike the mere copying of a person, or the substitution of one person for another, it implies a type of emulation. Starting with the dialogue of the Canon of Toledo (I, 49-50, this paper shows how, in his mimetic behavior, Don Quijote understands imitation as emulation. As a result, the paper shows that the effect of literature on the gentleman from La Mancha is the type of mimesis of which Plato approves in book III of the Republic.

Full Text Available Asteroid 1983 SA, well known as 3552 Don Quixote, is one of Near Earth Asteroids (NEAs which is the most probable candidate for the cometary origin, or otherwise as Jupiter-Family-Comets (JFCs. The aim of this study is to investigate the possibility of 3552 Don Quixote to be ejected from the Solar System. This paper presents an orbital evolution of 100 hypothetical asteroids generated by cloning 3552 Don Quixote. Investigation of its orbital evolution is conducted by using the SWIFT subroutine package, where the gravitational perturbations of eight major planets in the Solar System are considered. Over very short time scales (220 kyr relative to the Solar System life time (10 Gyr, the asteroid 3552 Don Quixote gave an example of chaotic motion that can cause asteroid to move outward and may be followed by escaping from the Solar System. Probability of ejection within the 220 kyr time scale is 50%.

The Authors of the Ingenious Hidalgo Don Quixote of La Mancha

Directory of Open Access Journals (Sweden)

Branka Kalenić Ramšak

2008-12-01

Full Text Available Even today literary criticism still considers the novel Don Quixote the first modern European novel because it fundamentally changes both the concept of literary creation and the findings regarding literary reception. Miguel de Cervantes Saavedra published the first part of his chivalric novel in 1605 in Madrid with the title El ingenioso hidalgo don Quijote de la Mancha. He published the second part, titled El ingenioso caballero don Quijote de la Mancha, ten years later (i.e., in 1615, again in Madrid. Why did Cervantes change the title in the second part of his novel and thus transform Don Quixote the hidalgo ‘nobleman’ into Don Quixote the caballero ‘knight, nobleman, horseman’? In Spanish literature of Cervantes’ time, writers often borrowed texts from one another, wrote sequels to them, and reworked them into humorous poems, jocular one-act plays, or unusual parodies. The Baroque concept of imitation was not understood as plagiarism, but rather as a positive approach to creativity. One of Cervantes’ most enthusiastic imitators was Alonso Fernández de Avellaneda. He hated Cervantes, but loved Don Quixote so much that he wrote a sequel to it in the form of a chivalric novel. In 1614, Avellaneda published his novel titled Segundo tomo del ingenioso hidalgo don Quijote de la Mancha (The Second Part of the Ingenious Hidalgo of La Mancha in Tarragona. Who is hidden behind the name Alonso Fernández de Avellaneda? To date, literary history has not been able to establish with certainty who the author of this “second part” was; this work represents the greatest literary mystery of all time in Spanish literature. In the 1960s a theory developed among Cervantes experts that for now seems to be the most convincing in determining Avellaneda’s true identity. In his article “ El Quijote y los libros” (Don Quixote and Books of 1969, Martín de Riquer presented the first well-founded hypothesis claiming that the writer Alonso Fern

Full Text Available Don Quixote has ridden with us for a long time now, and as if his fight against windmills were not enough, Don Quixote still has many more difficult situations to combat in the present times. Will the Knight of the Sad Figure accomplish this new deed? It is our challenge to find an answer to this inquiry. For this purpose, the author of this essay inserts the Knight of the Sad Figure in XXI century society. The author transforms the values, costumes and points of view of the times of the literary piece and establishes a series of relationships between the literary text, the main character and several current daily life situations. Don Quixote will certainly continue his fight against all the conditions we encounter nowadays. There is no doubt, then, that this knight still lives among us.

2014-12-01

Full Text Available This article brings to light a group of Cervantine English literary works hitherto unknown to present-day Cervantes studies: seven theatrical adaptations of Don Quixote (two anonymous ones in addition to those by Charles Dibdin, Joseph Moser, G. A. Macfarren, C. A. Maltby and P. Milton, a comedy with a Quixotic title (by George Dance, and five Quixotic fictions (two anonymous, in addition to those by Lily Spender, Maurice Hewlett and A. T. Quiller-Couch. Three of these plays, had been noted by Leopoldo Rius in 1899 (Moser, Macfarren, Maltby; the other four are presented for the first time here. In order to chart a fuller and more complete history of Don Quixote on the English stage, this article provides relevant information on those seven plays. An examination of these works reinforces the previous theses that underscore the essentially comical nature of Quixotic plays in nineteenth-century England, a fact of relevance in the study of the English reception of Don Quixote in the course of that century.

Dostoyevski and Don Quijote: Poetics and Aesthetics of a Delusion

Tamara Djermanovic

2015-12-01

Full Text Available In Fedor Mikhailovich Dostoevsky’s body of work (1821-1881 one can find more than thirty references to Don Quixote; while some of them allude to the novel of Don Quixote itself, other ones refer to Cervantes’ hero as an archetypal figure. Since decades ago, the Russian literary criticism has been interested in the Russian quixotism – including Dostoevsky’s work – and important studies on this subject have been published recently. This study follows Dostoevsky’s references on La Mancha’s Knight as an independent figure of Cervantes’ novel, and the different symbolism Don Quixote’s figure has had in both Russian people and Russian intelligentsia.

Effect of test exercises and mask donning on measured respirator fit.

Science.gov (United States)

Crutchfield, C D; Fairbank, E O; Greenstein, S L

1999-12-01

Quantitative respirator fit test protocols are typically defined by a series of fit test exercises. A rationale for the protocols that have been developed is generally not available. There also is little information available that describes the effect or effectiveness of the fit test exercises currently specified in respiratory protection standards. This study was designed to assess the relative impact of fit test exercises and mask donning on respirator fit as measured by a controlled negative pressure and an ambient aerosol fit test system. Multiple donnings of two different sizes of identical respirator models by each of 14 test subjects showed that donning affects respirator fit to a greater degree than fit test exercises. Currently specified fit test protocols emphasize test exercises, and the determination of fit is based on a single mask donning. A rationale for a modified fit test protocol based on fewer, more targeted test exercises and multiple mask donnings is presented. The modified protocol identified inadequately fitting respirators as effectively as the currently specified Occupational Safety and Health Administration (OSHA) quantitative fit test protocol. The controlled negative pressure system measured significantly (p < 0.0001) more respirator leakage than the ambient aerosol fit test system. The bend over fit test exercise was found to be predictive of poor respirator fit by both fit test systems. For the better fitting respirators, only the talking exercise generated aerosol fit factors that were significantly lower (p < 0.0001) than corresponding donning fit factors.

Dissolved organic nitrogen (DON) profile during backwashing cycle of drinking water biofiltration.

Science.gov (United States)

Liu, Bing; Gu, Li; Yu, Xin; Yu, Guozhong; Zhang, Huining; Xu, Jinli

2012-01-01

A comprehensive investigation was made in this study on the variation of dissolved organic nitrogen (DON) during a whole backwashing cycle of the biofiltration for drinking water treatment. In such a cycle, the normalized DON concentration (C(effluent)/C(influent)) was decreased from 0.98 to 0.90 in the first 1.5h, and then gradually increased to about 1.5 in the following 8h. Finally, it remained stable until the end of this 24-hour cycle. This clearly 3-stage profile of DON could be explained by three aspects as follows: (1) the impact of the backwashing on the biomass and the microbial activity; (2) the release of soluble microbial products (SMPs) during the biofiltration; (3) the competition between heterotrophic bacteria and nitrifying bacteria. All the facts supported that more DON was generated during later part of the backwashing cycle. The significance of the conclusion is that the shorter backwashing intervals between backwashing for the drinking water biofilter should further decrease the DON concentration in effluent of biofilter.

Goldbach, Jeremy T; Castro, Carl Andrew

2016-06-01

Lesbian, gay, and bisexual service members can serve openly in the military with the repeal of the Don't Ask, Don't Tell policy. The fate of transgender service members remains uncertain as the policy preventing them from serving in the military remains under review. The health care needs of these populations remain for the most part unknown, with total acceptance and integration in the military yet to be achieved. In this paper, we review the literature on the health care needs of lesbian, gay, bisexual, and transgender (LGBT) service members, relying heavily on what is known about LGBT civilian and veteran populations. Significant research gaps about the health care needs of LGBT service members are identified, along with recommendations for closing those gaps. In addition, recommendations for improving LGBT acceptance and integration within the military are provided.

MFS Transporters and GABA Metabolism Are Involved in the Self-Defense Against DON in Fusarium graminearum

Directory of Open Access Journals (Sweden)

Qinhu Wang

2018-04-01

Full Text Available Trichothecene mycotoxins, such as deoxynivalenol (DON produced by the fungal pathogen, Fusarium graminearum, are not only important for plant infection but are also harmful to human and animal health. Trichothecene targets the ribosomal protein Rpl3 that is conserved in eukaryotes. Hence, a self-defense mechanism must exist in DON-producing fungi. It is reported that TRI (trichothecene biosynthesis 101 and TRI12 are two genes responsible for self-defense against trichothecene toxins in Fusarium. In this study, however, we found that simultaneous disruption of TRI101 and TRI12 has no obvious influence on DON resistance upon exogenous DON treatment in F. graminearum, suggesting that other mechanisms may be involved in self-defense. By using RNA-seq, we identified 253 genes specifically induced in DON-treated cultures compared with samples from cultures treated or untreated with cycloheximide, a commonly used inhibitor of eukaryotic protein synthesis. We found that transporter genes are significantly enriched in this group of DON-induced genes. Of those genes, 15 encode major facilitator superfamily transporters likely involved in mycotoxin efflux. Significantly, we found that genes involved in the metabolism of gamma-aminobutyric acid (GABA, a known inducer of DON production in F. graminearum, are significantly enriched among the DON-induced genes. The GABA biosynthesis gene PROLINE UTILIZATION 2-2 (PUT2-2 is downregulated, while GABA degradation genes are upregulated at least twofold upon treatment with DON, resulting in decreased levels of GABA. Taken together, our results suggest that transporters influencing DON efflux are important for self-defense and that GABA mediates the balance of DON production and self-defense in F. graminearum.

Composition, sources, and bioavailability of nitrogen in a longitudinal gradient from freshwater to estuarine waters.

Science.gov (United States)

Jani, Jariani; Toor, Gurpal S

2018-06-15

Nitrogen (N) transport from land to water is a dominant contributor of N in estuarine waters leading to eutrophication, harmful algal blooms, and hypoxia. Our objectives were to (1) investigate the composition of inorganic and organic N forms, (2) distinguish the sources and biogeochemical mechanisms of nitrate-N (NO 3 -N) transport using stable isotopes of NO 3 - and Bayesian mixing model, and (3) determine the dissolved organic N (DON) bioavailability using bioassays in a longitudinal gradient from freshwater to estuarine ecosystem located in the Tampa Bay, Florida, United States. We found that DON was the most dominant N form (mean: 64%, range: 46-83%) followed by particulate organic N (PON, mean: 22%, range: 14-37%), whereas inorganic N forms (NO x -N: 7%, NH 4 -N: 7%) were 14% of total N in freshwater and estuarine waters. Stable isotope data of NO 3 - revealed that nitrification was the main contributor (36.4%), followed by soil and organic N sources (25.5%), NO 3 - fertilizers (22.4%), and NH 4 + fertilizers (15.7%). Bioassays showed that 14 to 65% of DON concentrations decreased after 5-days of incubation indicating utilization of DON by microbes in freshwater and estuarine waters. These results suggest that despite low proportion of inorganic N forms, the higher concentrations and bioavailability of DON can be a potential source of N for algae and bacteria leading to water quality degradation in the estuarine waters.

DON JUAN: THE DISCOURSE OF SEDUCTION AS AN EXERCISE OF POWER

Directory of Open Access Journals (Sweden)

Kristina Stankevičiūtė

2016-10-01

Full Text Available The figure of Don Juan that emerged in Spanish baroque synthesised several important cultural issues related to the phenomenon of seduction, a subject of great social controversy since the very beginning of the Christian era. The present article analyses one of the fundamental parts of the universal appeal of the Don Juan figure – the discourse of seduction, considering it from the social and cultural point of view. The traditional discussion of the subject focuses on the contents of the discourse whereas the present article emphasises the implications rather than the contents, grounding its arguments on Jean Baudrillard’s theory of seduction, which claims that it is the signs and the play of signs that are important in seduction, not their meanings. The seduction discourse is seen as a means to exercise power on the women that Don Juan deals with as well as on the audience who gets involved into the discourse creation process. The article concludes with a claim that Don Juan is a figure of social domination, and his discourse is a means to achieve it.

Embryotoxicity Caused by DON-Induced Oxidative Stress Mediated by Nrf2/HO-1 Pathway

Directory of Open Access Journals (Sweden)

Miao Yu

2017-06-01

Full Text Available Deoxynivalenol (DON belongs to the type B group of trichothecenes family, which is composed of sesquiterpenoid metabolites produced by Fusarium and other fungi in grain. DON may cause various toxicities, such as cytotoxicity, immunotoxicity, genotoxicity as well as teratogenicity and carcinogenicity. In the present study, we focus on a hypothesis that DON alters the expressions of Nrf2/HO-1 pathway by inducing embryotoxicity in C57BL/6 mouse (5.0, 2.5, 1.0, and 0 mg/kg/day and BeWo cell lines (0 and 50 nM; 3 h, 12 h and 24 h. Our results indicate that DON treatment in mice during pregnancy leads to ROS accumulation in the placenta, which results in embryotoxicity. At the same time Nrf2/HO-1 pathway is up-regulated by ROS to protect placenta cells from oxidative damage. In DON-treated BeWo cells, the level of ROS has time–effect and dose–effect relationships with HO-1 expression. Moderate increase in HO-1 protects the cell from oxidative damage, while excessive increase in HO-1 aggravates the oxidative damage, which is called in some studies the “threshold effect”. Therefore, oxidative stress may be the critical molecular mechanism for DON-induced embryotoxicity. Besides, Nrf2/HO-1 pathway accompanied by the “threshold effect” also plays an important role against DON-induced oxidative damage in this process.

Mixing regime as a key factor to determine DON formation in drinking water biological treatment.

Science.gov (United States)

Lu, Changqing; Li, Shuai; Gong, Song; Yuan, Shoujun; Yu, Xin

2015-11-01

Dissolved organic nitrogen (DON) can act as precursor of nitrogenous disinfection by-products formed during chlorination disinfection. The performances of biological fluidized bed (continuous stirred tank reactor, CSTR) and bio-ceramic filters (plug flow reactor, PFR) were compared in this study to investigate the influence of mixing regime on DON formation in drinking water treatment. In the shared influent, DON ranged from 0.71mgL(-1) to 1.20mgL(-1). The two biological fluidized bed reactors, named BFB1 (mechanical stirring) and BFB2 (air agitation), contained 0.12 and 0.19mgL(-1) DON in their effluents, respectively. Meanwhile, the bio-ceramic reactors, labeled as BCF1 (no aeration) and BCF2 (with aeration), had 1.02 and 0.81mgL(-1) DON in their effluents, respectively. Comparative results showed that the CSTR mixing regime significantly reduced DON formation. This particular reduction was further investigated in this study. The viable/total microbial biomass was determined with propidium monoazide quantitative polymerase chain reaction (PMA-qPCR) and qPCR, respectively. The results of the investigation demonstrated that the microbes in BFB2 had higher viability than those in BCF2. The viable bacteria decreased more sharply than the total bacteria along the media depth in BCF2, and DON in BCF2 accumulated in the deeper media. These phenomena suggested that mixing regime determined DON formation by influencing the distribution of viable, total biomass, and ratio of viable biomass to total biomass.

Full Text Available Deoxynivalenol (DON frequently contaminates animal feed, including fish feed used in aquaculture. This study intends to further investigate the effects of DON on carp (Cyprinus carpio L. at concentrations representative for commercial fish feeds. Experimental feeding with 352, 619 or 953 μg DON kg−1 feed resulted in unaltered growth performance of fish during six weeks of experimentation, but increased lipid peroxidation was observed in liver, head kidney and spleen after feeding of fish with the highest DON concentration. These effects of DON were mostly reversible by two weeks of feeding the uncontaminated control diet. Histopathological scoring revealed increased liver damage in DON-treated fish, which persisted even after the recovery phase. At the highest DON concentration, significantly more fat, and consequently, increased energy content, was found in whole fish body homogenates. This suggests that DON affects nutrient metabolism in carp. Changes of lactate dehydrogenase (LDH activity in kidneys and muscle and high lactate levels in serum indicate an effect of DON on anaerobic metabolism. Serum albumin was reduced by feeding the medium and a high dosage of DON, probably due to the ribotoxic action of DON. Thus, the present study provides evidence of the effects of DON on liver function and metabolism.

Don Quijote en Barcelona, El caballero de la triste figura, En un lugar de Manhattan, Elogio de la locura and En un lugar del Quijote. The analysis covers the main features of such adaptations: metanarration, metadrama, doubling of the narrative structure using other artistic languages (music, plastic arts, dance, etc., new technologies, genre hybridisation, transmediality, etc. The original text message, actualised and re-expressed by these modernisations, stands out as an atemporal one: the plays examined demonstrate its effectiveness in contemporary society and, according to the perspective of social theater, stimulate the reflection on them.

Evaluation of genetic toxicity of 6-diazo-5-oxo-l-norleucine (DON).

Science.gov (United States)

Kulkarni, Rohan M; Dakoulas, Emily W; Miller, Ken E; Terse, Pramod S

2017-09-01

DON (6-diazo-5-oxo-l-norleucine), a glutamine antagonist, was demonstrated to exhibit analgesic, antibacterial, antiviral and anticancer properties. The study was performed to characterize its in vitro and in vivo genetic toxicity potential. DON was tested in the bacterial reverse mutation assay (Ames test) using Salmonella typhimurium tester strains (TA98, TA100, TA1535 and TA1537) and Escherichia coli tester strain (WP2 uvrA) with and without S9 and also with reductive S9. In addition, DON was tested for the chromosome aberrations in Chinese hamster ovary (CHO) cells with or without S9 to evaluate the clastogenic potential. Furthermore, DON was also evaluated for its in vivo clastogenic activity by detecting micronuclei in polychromatic erythrocyte (PCE) cells in bone marrow collected from the male mice dosed intravenously with 500, 100, 10, 1 and 0.1 mg/kg at 24 and 48-h post-dose. The Ames mutagenicity assay showed no positive mutagenic responses. However, the in vitro chromosome aberration assay demonstrated dose dependent statistically positive increase in structural aberrations at 4 and 20-h exposure without S9 and also at 4-h exposure with S9. The in vivo micronucleus assay also revealed a statistically positive response for micronucleus formation at 500, 100 and 10 mg/kg at 24 and 48-h post-dose. Thus, DON appears to be negative in the Ames test but positive in the in vitro chromosome aberration assay and in the in vivo micronucleus assay. In conclusion, the results indicate DON is a genotoxic compound with a plausible epigenetic mechanism.

Sources and transformation of dissolved and particulate organic nitrogen in the North Pacific Subtropical Gyre indicated by compound-specific δ15N analysis of amino acids

Science.gov (United States)

Yamaguchi, Yasuhiko T.; McCarthy, Matthew D.

2018-01-01

This study explores the use of compound-specific nitrogen isotopes of amino acids (δ15NAA) of coupled dissolved and particulate organic nitrogen (DON, PON) samples as a new approach to examine relative sources, transformation processes, and the potential coupling of these two major forms of N cycle in the ocean water column. We measured δ15NAA distributions in high-molecular-weight dissolved organic nitrogen (HMW DON) and suspended PON in the North Pacific Subtropical Gyre (NPSG) from surface to mesopelagic depths. A new analytical approach achieved far greater δ15NAA measurement precision for DON than earlier work, allowing us to resolve previously obscured differences in δ15NAA signatures, both with depth and between ON pools. We propose that δ15N values of total hydrolysable amino acids (THAA) represents a proxy for proteinaceous ON δ15N values in DON and PON. Together with bulk δ15N values, this allows δ15N values and changes in bulk, proteinaceous, and ;other-N; to be directly evaluated. These novel measurements suggest three main conclusions. First, the δ15NAA signatures of both surface and mesopelagic HMW DON suggest mainly heterotrophic bacterial sources, with mesopelagic HMW DON bearing signatures of far more degraded material compared to surface material. These results contrast with a previous proposal that HMW DON δ15NAA patterns are essentially ;pre-formed; by cyanobacteria in the surface ocean, undergo little change with depth. Second, different δ15NAA values and patterns of HMW DON vs. suspended PON in the surface NPSG suggest that sources and cycling of these two N reservoirs are surpisingly decoupled. Based on molecular δ15N signatures, we propose a new hypothesis that production of surface HMW DON is ultimately derived from subsurface nitrate, while PON in the mixed layer is strongly linked to N2 fixation and N recycling. In contrast, the comparative δ15NAA signatures of HMW DON vs. suspended PON in the mesopelagic also suggest a

The myth of the warrior: martial masculinity and the end of Don't Ask, Don't Tell.

Science.gov (United States)

Allsep, L Michael

2013-01-01

The image of the male warrior still dominates military culture, to the exclusion of women and homosexuals. Complicating the picture is a technological revolution that promises to widen the current gap between the myth and reality of the modern warrior even further. Nonetheless, despite long arguing that homosexuals were a direct threat to military culture and effectiveness, the Pentagon has largely treated the end of Don't Ask, Don't Tell as a policy matter. The difficulties still experienced by women in the armed services 40 years after they were first incorporated in significant numbers indicates that this response will be insufficient to address the deeper cultural issues. Gender issues implicate deeply held beliefs and values that persist even in the face of years of official admonishment and denial. Unless the military begins to transparently bridge the gap between the myth and reality of the modern warrior, military service without discrimination based on sexual orientation will remain an unachieved goal.

Science and Fiction. On Don Quijote’s Epistemological Skepticism

Directory of Open Access Journals (Sweden)

Félix Schmelzer

2016-11-01

Full Text Available The present work seeks to analyze the representation of scientific knowledge in Cervantes’ Quixote, focusing on various passages that underline the scientific expertise of don Quixote himself. It is shown that the novel contains a subtle critique of science, based on an epistemological skepticism with regard to the arbitrariness of our world concepts. The characterization of don Quixote as a man of science even permits deducting that he suffers from a ‘double mental damage’, caused by the lecture of both books of cavalry and science. Cervantes thus would consider science to be fiction, a very modern point of view.

Sleep and sleep disorders in Don Quixote.

Science.gov (United States)

Iranzo, Alex; Santamaria, Joan; de Riquer, Martín

2004-01-01

In Don Quijote de la Mancha, Miguel de Cervantes presents Don Quixote as an amazing character of the 17th century who suffers from delusions and illusions, believing himself to be a medieval knight errant. Besides this neuropsychiatric condition, Cervantes included masterful descriptions of several sleep disorders such as insomnia, sleep deprivation, disruptive loud snoring and rapid eye movement sleep behaviour disorder. In addition, he described the occurrence of physiological, vivid dreams and habitual, post-prandial sleepiness--the siesta. Cervantes' concept of sleep as a passive state where all cerebral activities are almost absent is in conflict with his description of abnormal behaviours during sleep and vivid, fantastic dreams. His concept of sleep was shared by his contemporary, Shakespeare, and could have been influenced by the reading of the classical Spanish book of psychiatry Examen de Ingenios (1575).

Don Stookey, the father of glass-ceramics, was a pioneer in inducing and understanding internal nucleation phenomena in glass. His early work on dense opal glasses and photosensitive precipitation of gold and silver in glass led to an amazing series of inventions: Fotalite, a photosensitive opal, chemically machined Fotoform and Fotoceram, and TiO2-nucleated Pyroceram products including missile nosecones and oven-proof cookware. He received a basic patent on glass-ceramics, which was contested and affirmed in court. Don was able to demonstrate a clear photochromic glass that showed reversible darkening for thousands of cycles. This material became a fixture in the ophthalmic industry. He went on to invent a full-color polychromatic glass, capable of yielding a permanent patterned and monolithic stained glass. In his life outside science, Don chaired an interfaith group that founded a home for the elderly in Corning. He was also a wilderness enthusiast, surviving a plane crash in the Arctic and two boat capsizings. Even in his later years, he continued fishing off the coast of Florida and on Lake Ontario and went solo on a trip to the Patagonian Andes. Don Stookey was a special person by any measure: an unassuming optimist, eminent scientist and inventor, adventurer, and a beloved family man. Introduction

Full Text Available In 1898, Spanish press take up part of its pages with a relevant international issue: the Dreyfus affair. The case was widely covered by Spanish newspapers, in special by Don Quijote, a Madrilenian satiric press, whose Director promoted a campaign in favour of Zola collecting signatures in order to the French litterateur was aware that Spain was close to him. This initiative is completed with a call to Spanish young people who is illustrated with a quixotic caricature. Cervantine character personifies the idea of justice getting to transmit during the Spanish crisis at the end of the nineteenth century the image of the nobleman forged by Spanish stereotypical, like a crusader fighting for a noble cause, thus turning Don Quixote into another dreyfussard.

Transient identification system with noising data and 'don't know' response

International Nuclear Information System (INIS)

Mol, Antonio C. de A.; Martinez, Aquilino S.; Schirru, Roberto

2002-01-01

In the last years, many different approaches based on neural network (NN) has been proposed for transient identification in nuclear power plants (NPP). Some of them focus the dynamic identification using recurrent neural networks however, they are not able to deal with unrecognized transients. Other kind of solution uses competitive learning in order to allow the 'don't know' response. In this case dynamic, dynamic features are not well represented. This work presents a new approach for neural network based transient identification which allows either dynamic identification and 'don't know'response. Such approach uses two multilayer neural networks trained with backpropagation algorithm. The first one is responsible for the dynamic identification. This NN uses, a short set (in a movable time window) of recent measurements of each variable avoiding the necessity of using starting events. The other one is used to validate the instantaneous identification (from the first net) through the validation of each variable. This net is responsible for allowing the system to provide 'don't know' response. In order to validate the method a NPP transient identification problem comprising 15 postulated accidents, simulated for a pressurized water reactor, was proposed in the validation process it has been considered noising data in other to evaluate the method robustness. Obtained results reveal the ability of the method in dealing with both dynamic identification of transients and correct 'don't know' response. In order to validate the method, a NPP transient identification problem comprising 15 postulated accidents simulated for a pressurized water reactor, was proposed in the validation process it has been considered noising data in order to evaluate the method robustness.

2016-01-01

The Internet has contributed new words and slang to our daily vernacular. A few terms, such as tweeting, texting, sexting, blogging, and googling, have become common in most vocabularies and in many languages, and are now included in the dictionary. A new buzzword making the rounds in industry is crowd sourcing, which involves outsourcing an activity, task, or problem by sending it to people or groups outside a business or a practice. Crowd sourcing allows doctors and practices to tap the wisdom of many instead of relying only on the few members of their close-knit group. This article defines "crowd sourcing," offers examples, and explains how to get started with this approach that can increase your ability to finish a task or solve problems that you don't have the time or expertise to accomplish.

The voice of Cervantes «creator» in Don Quixote

Full Text Available The aim of this paper is identifying the genuine voice of the Cervantes creator in the multiple choir of fictitious intermediaries involved in the authorship and the story of Don Quijote (reporter, editor, translator, Cide Hamete, supernarrator, readers, etc. trying, at the same time, to gauging the sense and the scope of their interventions. It happens that Miguel de Cervantes keeps to himself a novelistic role radically different depending on whether it is about the «story of story» or the «story itself»: refering to the first one, the author is out of the cast, delegating the reconstruction of Don Quixote’s legend in multiple fictional masks always comically manipulated; on the other hand, when it is the turn to the novelistic design of the chivalrous adventures of Don Quixote and Sancho, the voice of Cervantes creator comes to the forefront in order to take on, —as the «final author»— all narrative responsibility with absolute omniscience and solemnity. The resulting Quijote can only be explained from the intersection of both attitudes: the risible story of the most solemn/serious and magnificent novelistic bet never tried out..

Bioanalysis of 6-Diazo-5-oxo-L-norleucine (DON) in plasma and brain by ultra-performance liquid chromatography mass spectrometry

Alt, Jesse; Potter, Michelle C.; Rojas, Camilo; Slusher, Barbara S.

2015-01-01

Glutamine is an abundant amino acid that plays pivotal roles in cell growth, cell metabolism and neurotransmission. Dysregulation of glutamine-utilizing pathways has been associated with pathological conditions such as cancer and neurodegenerative diseases. 6-Diazo-5-Oxo-L-Norleucine (DON) is a reactive glutamine analog that inhibits enzymes affecting glutamine metabolism such as glutaminase, 2-N-amidotransferase, L-asparaginase and several enzymes involved in pyrimidine and purine de novo synthesis. As a result, DON is actively used in preclinical models of cancer and neurodegenerative disease. Moreover, there have been several clinical trials using DON to treat a variety of cancers. Considerations of dose and exposure are especially important with DON treatment due to its narrow therapeutic window and significant side effects. Consequently, a robust quantification bioassay is of interest. DON is a polar unstable molecule which has made quantification challenging. Here we report on the characterization of a bioanalytical method to quantify DON in tissue samples involving DON derivatization with 3N HCl in butanol. The derivatized product is lipophilic and stable. Detection of this analyte by mass spectrometry is fast, specific and can be used to quantify DON in plasma and brain tissue with a limit of detection in the low nanomolar level. PMID:25584882

Don Quixote and Roque Guinart against the way of life of the influential people

Full Text Available The apocryphal Second part of don Quixote altered many of the purposes of Cervantes. He changed the destination of his hero. As observed by don Quixote when visiting a printinghouse, its publication took place in Barcelona. The author gave prominence to a town as in picaresque novels. However, he did not modify his attitude towards the behaviour of the influential people, in keeping with Erasmus’ concept of stupidity. Surely, Cervantes reaffirmed his approach to the golden age through the presence of Roque Guinart, the only historical character who appears in the novel. This paper examines how the influential people behave in front of don Quixote, and how his performance is similar to that of Roque Guinart.

There is considerable confusion in the field of research on the history of psychiatry as to who created the term anancasm. This article seeks to clarify that the term was coined by the Hungarian psychiatrist Gyula Donáth, who was born in Baja, on the Danube, and worked mainly in Budapest. Donáth's publications reveal that his predominant sphere of interest and research was neurology and psychiatry. A number of his publications deal with epilepsy and obsessive-compulsive disorders. After a period of intensive research, during which he spent some time in Berlin at the clinic of neuroscientist Carl Westphal, Donáth proposed the term 'anancasm' in 1895 to describe compulsive mental processes. © The Author(s) 2015.

Six pregnant sows of 180.6 ± 5.6 kg were fed either a Fusarium-contaminated (4.42 mg DON and 48.3 µg ZON per kg, DON per os, n = 3) or a control diet (0.15 mg DON and 5 µg ZON/kg) in the period of days 63 and 70 of gestation. On day 63 of gestation, sows fed the control diet were implanted with an intraperitoneal osmotic minipump (delivery rate of 10 µL/h, for 7 days) containing 50 mg pure (98%) DON in 2 ml 50% DMSO (DON ip, n = 3). Frequent plasma samples were taken to estimate the kinetics after oral and ip DON exposure. The intended continuous delivery of DON by the intraperitoneal minipump could not be shown, as there was a plasma peak (Cmax) of 4.2-6.4 ng DON/mL either immediately (sow IP-2+3) or 2.5 h (sow IP-1) after implantation of the pump followed by a one-exponential decline with a mean half-time (t1/2) of 1.75-4.0 h and only negligible DON plasma concentrations after 12 h. Therefore, the DON ip exposure has to be regarded as one single dose 1 week before termination of experiment. The DON per os sows showed a mean basis level (after achieving a steady state) of DON plasma concentration of about 6-8 ng/mL, as also indicated by the plasma DON concentration at the termination of the experiment. On day 70, caesarean section was carried out, the fetuses were killed immediately after birth, and samples of plasma, urine, and bile were taken to analyze the concentration of DON and its metabolite de-epoxy-DON. At necropsy there were no macroscopic lesions observed in any organ of either sows or piglets. Histopathological evaluation of sows liver and spleen revealed no alterations. The proliferation rate of peripheral blood mononuclear cells (PBMC) with or without stimulation was not affected by the kind of DON treatment. The exposure of pregnant sows at mid-gestation (days 63-70, period of organogenesis) to a Fusarium toxin-contaminated diet (4.42 mg DON and 0.048 mg ZON per kg) or pure DON via intraperitoneal osmotic minipump

Full text: The Don Pao Rare Earth Deposit was discovered in 1959 in Phon Tho district, about 450km North-West of Hanoi capital. Geological work was conducted between 1959-95, resulting in 60 ore bodies of various sizes being identified. The ore bodies are irregularly shaped nests, lenses and veins hosted in the shear zone, at the margin of a Paeleogene aged syenite massif. The mineral composition of Don Pao Deposit is very complex, consisting of more than 50 minerals. Among them, basnaesite, parisite, fluorite and barite are the main constituent minerals of the ore. All the minerals were identified by the modern methods of mineralogical studies. Based on the constituent mineral ratios, four ore types have been distinguished in the deposit: 1. Rare earth ore containing over 5 percent of RE 2 O 3 . 2. Rare Earth-Barite ore containing 0.5 to 30 percent of RE 2 O 3 . 3. Rare Earth-Barite-Fluorite ore containing 1 to 5 percent of RE 2 O 3 . 4. Rare Earth bearing Fluorite ore containing 1 to 5 percent of RE 2 O 3 . According to the benefication test, the ores in Don Pao can be enriched to a concentrate of 60 percent of RE 2 O 3 with a recover of 75 percent

Deoxynivalenol (DON Contamination of Feed and Grinding Fineness: Are There Interactive Implications on Stomach Integrity and Health of Piglets?

Directory of Open Access Journals (Sweden)

Sven Dänicke

2017-01-01

Full Text Available The common feed contaminant deoxynivalenol (DON was reported to influence the morphology of the pars nonglandularis (PN of porcine stomach. Moreover, finely ground feed is known to trigger the development of ulcers and other pathologies of PN while coarsely ground feed protects from such lesions. The interactions between grinding fineness and DON contamination of feed were not examined so far. Therefore, both finely and coarsely ground feeds were tested either in the absence or presence of a DON contaminated wheat on growth performance and health of rearing piglets, including stomach integrity. DON contamination significantly reduced feed intake and serum albumin concentration with this effect being more pronounced after feeding the coarsely ground feed. Albeit at a higher level, albumin concentration was also reduced after feeding the finely ground and uncontaminated feed. Finely ground and DON-contaminated feed caused a significantly more pronounced lymphoplasmacytic infiltration both of PN and pars glandularis, partly paralleled by lymph follicle formation and detritus filled foveolae and tubes suggesting a local immune response probably triggered by epithelial lesions. It is concluded that DON contamination of feed exacerbates the adverse effects of finely ground feed on stomach mucosal integrity.

The workshop of Don Carlos lasts twenty years, from 1866 to 1886, when Verdi (reopens and closes several other workshops (Simon Boccanegra, La forza del destino, Aida, Requiem, Otello, creating a porous work in progress, whose analysis keeps giving us surprises. The libretto by Joseph Méry et Camille Du Locle, under the supervision of the composer, is a palimpsest where, under the official text referable to the common historical nucleus and its best known literary versions, some hidden or deleted heterogeneous texts appear, in a supranational, multilinguistic, intercultural and intertextual dimension, not always stirring along the road of a locatable derivation, of a voluntary imitation, but sometimes taking the shape of an unpredictable dissemination.

Deoxynivalenol (DON) or vomitoxin is a commonly encountered type-B trichothecene mycotoxin, produced by Fusarium species predominantly found in cereals and grains. DON is known to exert toxic effects on the gastrointestinal, reproductive and neuroendocrine systems, and particularly on the immune system. Depending on dose and exposure time, it can either stimulate or suppress immune function. The main objective of this study was to obtain a deeper insight into DON-induced effects on lymphoid cells. For this, we exposed the human T-lymphocyte cell line Jurkat and human peripheral blood mononuclear cells (PBMCs) to various concentrations of DON for various times and examined gene expression changes by DNA microarray analysis. Jurkat cells were exposed to 0.25 and 0.5 μM DON for 3, 6 and 24 h. Biological interpretation of the microarray data indicated that DON affects various processes in these cells: It upregulates genes involved in ribosome structure and function, RNA/protein synthesis and processing, endoplasmic reticulum (ER) stress, calcium-mediated signaling, mitochondrial function, oxidative stress, the NFAT and NF-κB/TNF-α pathways, T cell activation and apoptosis. The effects of DON on the expression of genes involved in ER stress, NFAT activation and apoptosis were confirmed by qRT-PCR. Other biochemical experiments confirmed that DON activates calcium-dependent proteins such as calcineurin and M-calpain that are known to be involved in T cell activation and apoptosis. Induction of T cell activation was also confirmed by demonstrating that DON activates NFATC1 and induces its translocation from the cytoplasm to the nucleus. For the gene expression profiling of PBMCs, cells were exposed to 2 and 4 μM DON for 6 and 24 h. Comparison of the Jurkat microarray data with those obtained with PBMCs showed that most of the processes affected by DON in the Jurkat cell line were also affected in the PBMCs. -- Highlights: ► The human T cell line Jurkat and human

The Rhetoric of Madness in Kathy Acker’s Don Quixote

Directory of Open Access Journals (Sweden)

Claudia Cao

2017-07-01

Full Text Available This essay examines the rhetorical experimentation of Don Quixote by Kathy Acker, starting from a theoretical concept central in the author’s thought: her search for a “language of the body”. A brief introduction to Kathy Acker’s plagiaristic poetics frames her narrative strategies between postmodern rewriting and pastiche. It shows the way in which her Don Quixote transposes the representative scheme of the chivalric quest into the contemporary value system with the aim of questioning Cervantes’ text as one of the canonical works of the Western literary tradition. The following section deepens three focal concepts of Acker’s theoretical works – body, madness, and norm – illuminating the connections between her rhetorical experimentation and the works by Luce Irigaray and Judith Butler. Finally, the paper will demonstrate how these concepts in Acker's rewriting of Don Quixote are strictly related to paradox, which she uses in order to actualize a “language of the body”: in the passage from the former novel to the postmodern work, madness has become the device which, from the semantic level to the rhetorical one, expresses Acker’s idea of language of the body, as an alternative and in contrast to the canonical language of the logos.

An intimate understanding of place: Charles Sauriol and Toronto’s Don River Valley, 1927-1989.

Science.gov (United States)

Bonnell, Jennifer

2011-01-01

Every summer from 1927 to 1968, Toronto conservationist Charles Sauriol and his family moved from their city home to a rustic cottage just a few kilometres away, within the urban wilderness of Toronto’s Don River Valley. In his years as a cottager, Sauriol saw the valley change from a picturesque setting of rural farms and woodlands to an increasingly threatened corridor of urban green space. His intimate familiarity with the valley led to a lifelong quest to protect it. This paper explores the history of conservation in the Don River Valley through Sauriol’s experiences. Changes in the approaches to protecting urban nature, I argue, are reflected in Sauriol’s personal experience – the strategies he employed, the language he used, and the losses he suffered as a result of urban planning policies. Over the course of Sauriol’s career as a conservationist, from the 1940s to the 1990s, the river increasingly became a symbol of urban health – specifically, the health of the relationship between urban residents and the natural environment upon which they depend. Drawing from a rich range of sources, including diary entries, published memoirs, and unpublished manuscripts and correspondence, this paper reflects upon the ways that biography can inform histories of place and better our understanding of individual responses to changing landscapes.

First, it enumerates the various activities that prove the author’s interest in Cervantes and his work, as well as the possible intervention of her mentor, Maria Martinez Sierra, in the genesis of the child’s character. Both novels, of dialogical nature, share an episodic structure articulated by a weak storyline. Its protagonists are animated by the desire to live the lives of the characters of their favorite readings. They confuse fantasy and reality causing situations whose results are almost always adverse. If Don Quixote dies back to the reason, so will Celia, the girl, with her entry into adulthood by resigning her fantasies, which will be taken up by new generations of children.

Vivisection au ralenti: Don DeLillo’s Point Omega

2014-12-01

Full Text Available Reading a Don DeLillo is like walking on glass, that is, you need hold your breath so that nothing could deter you from focusing on the mission, if you want to keep safe and mostly sound. The writer’s latest novel, Point Omega (2010, is no exception in that its author engages once more in the exercise of stripping away all surfaces so as to let us see into the terror of what he calls “makeshift reality”—his characters’ and ours. The claims I advance and substantiate in the essay, refer to (1 how a fluid chronology sustained by framing devices adds to the understanding of the construct of a novel/film in progress; (2 how the shifting narrative perspective ensures a vivisectionist’s look into the body of life/death/world. Don DeLillo’s novel is another terrifying X-ray of war/life/death as agonizing nothingness which literature in its ‘late-phase’ is meant to cure.

The case of a 50-year-old hidalgo who believed to be transformed into a knight-errant named Don Quijote is a megalomaniac systematized delusion of transformation of the self, a delusion of metamorphosis in reference to the patient's own identity. The outward projection of this syndrome produces some delusional misidentifications of others, things and animals and include elements of a persecutory delusion which increase the grandiosity of the self. At the same time the hidalgo was maniac with a pathway of bipolar disorder. The phenomenon of donquijotismo is described as the defence of wasted causes and Sancho Panza as an illiterate Sócrates.

De la risa a carcajadas al mal ejemplo quijotesco en la novela del XVIII. Don Quijote de la Manchuela

Directory of Open Access Journals (Sweden)

Full Text Available Don Quixote rapidly became a huge success. It was translated into several languages and reworked into genres with a festive and theatrical nature. In Spain, during the seventeenth century, its comic side was exploited, which provoked liberating laughter that, in France, led to its association with the satire genre. In the eighteenth century, the novel was considered a minor genre, of no educational value. The century began with a fierce controversy over the meaning of Cervantes’ work, since according to Rapin, some readers would have seen a mockery of the Spanish nobility in the insane gentleman. However, during the eighteenth century the first steps were taken to reappraise Don Quixote due to its acceptance as a classic by the Spanish Royal Academy in 1780. The Academy considered Don Quixote a mocking and didactic hero, a bad example to be avoided. Yet, the work was an important step in the construction of a new genre, the novel. Don Quijote de la Manchuela, by Donato de Arenzana (1767, reflects an attentive reading of Cervantes’ Don Quixote, and special attention to the neoclassical cannon. Therefore it can provide useful information about writers’ interests, in the preromantic eighteenth century.

Risk perceptions are legitimate targets for behavioral interventions because they can motivate medical decisions and health behaviors. However, some survey respondents may not know (or may not indicate) their risk perceptions. The scope of "don't know" (DK) responding is unknown. Examine the prevalence and correlates of responding DK to items assessing perceived risk of colorectal cancer. Two nationally representative, population-based, cross-sectional surveys (2005 National Health Interview Survey [NHIS]; 2005 Health Information National Trends Survey [HINTS]), and one primary care clinic-based survey comprised of individuals from low-income communities. Analyses included 31,202 (NHIS), 1,937 (HINTS), and 769 (clinic) individuals. Five items assessed perceived risk of colorectal cancer. Four of the items differed in format and/or response scale: comparative risk (NHIS, HINTS); absolute risk (HINTS, clinic), and "likelihood" and "chance" response scales (clinic). Only the clinic-based survey included an explicit DK response option. "Don't know" responding was 6.9% (NHIS), 7.5% (HINTS-comparative), and 8.7% (HINTS-absolute). "Don't know" responding was 49.1% and 69.3% for the "chance" and "likely" response options (clinic). Correlates of DK responding were characteristics generally associated with disparities (e.g., low education), but the pattern of results varied among samples, question formats, and response scales. The surveys were developed independently and employed different methodologies and items. Consequently, the results were not directly comparable. There may be multiple explanations for differences in the magnitude and characteristics of DK responding. "Don't know" responding is more prevalent in populations affected by health disparities. Either not assessing or not analyzing DK responses could further disenfranchise these populations and negatively affect the validity of research and the efficacy of interventions seeking to eliminate health disparities.

Full Text Available Most species belonging to Namanereis Chamberlin, 1919 live in freshwater and subterranean waters, even in water bodies several meters above sea level. A new species belonging to the stygobiont Namanereis group is described here; it shares the common morphological characters of absence of eyes and pigmentation, bifid jaws, elongation of chaetae and cirri, which have been recently regarded as troglomorphies. Because these features are used in evaluations of phylogenetic affinity in Namanereis, a review of these features was made for all known namanereidins, and it was extended to include species in Namalycastis Hartman, 1959. It is shown that elongation of tentacular and dorsal cirri, or elongation of upper sub-acicular falcigers in pre- or post-acicular fascicles, are not exclusive or restricted to species living in subterranean habitats or to Namanereis, because these features are also present in several Namalycastis species. However, the presence of bifid jaws, and the absence of eyes are exclusively found in namanereidins living in subterranean habitats. A hypothetical evolutionary derivation of bifid jaws is proposed, based upon observations of jaw morphology of several species. These exclusive troglomorphic characters (bifid jaws, eyeless are regarded as convergent features to aphotic environments, and they should be discouraged as indicators of common ancestry. The new species, herein described as Namanereis christopheri sp. n., was collected in a cave 435 m above sea level in Saint Vincent, Caribbean Sea. The species resembles N. cavernicola but it differs because it has shorter tentacular cirri, margin of prostomium entire, rounded neuropodial lobes and broader dorsal cirri throughout body. A key to identify all known Namanereis species is included.

Klein had been asked to contribute an article to the birthday number of the International Journal for Jones. The author outlines how she hurriedly wrote a text about Don Juan which, however, was rejected by the editor. Essential parts of it are presented in German translation. The manuscript is discussed in the context of Klein's published work as well as of the relevant contemporary literature. In Klein's view, Don Juan's genitality is determined by oral impulses and fears. By his manic acting out he attempts to ward off a depressive break-down. The paper ends with some reflections about why Klein--ontrary to her intention--failed to revise her manuscript for later publication.

Aim. To present specific aspects of adrenalectomy for Cushing's syndrome (CS) by introducing well established aspects ("do's") and less known aspects ("don'ts"). Material and Method. This is a narrative review. Results. The "do's" for laparoscopic adrenalectomy (LA) are the following: it represents the "gold standard" for secretor and non-secretor adrenal tumors and the first line therapy for CS with an improvement of cardio-metabolic co-morbidities; the success rate depending on the adequate patients' selection and the surgeon's skills. The "don'ts" are large (>6-8 centimeters), locally invasive, malignant tumors requiring open adrenalectomy (OA). Robotic adrenalectomy is a new alternative for LA, with similar safety and conversion rate and lower pain drugs use. The "don'ts" are the following: lack of randomized controlled studies including oncologic outcome, different availability at surgical centers. Related to the sub-types of CS, the "do's" are the following: adrenal adenomas which are cured by LA, while adrenocortical carcinoma (ACC) requires adrenalectomy as first line therapy and adjuvant mitotane therapy; synchronous bilateral adrenalectomy (SBA) is useful for Cushing's disease (only cases refractory to pituitary targeted therapy), for ectopic Cushing's syndrome (cases with unknown or inoperable primary site), and for bilateral cortisol producing adenomas. The less established aspects are the following: criteria of skilled surgeon to approach ACC; the timing of surgery in subclinical CS; the need for adrenal vein catheterization (which is not available in many centers) to avoid unnecessary SBA. Conclusion. Adrenalectomy for CS is a dynamic domain; LA overstepped the former OA area. The future will improve the knowledge related to RA while the cutting edge is represented by a specific frame of intervention in SCS, children and pregnant women. Abbreviations: ACC = adrenocortical carcinoma, ACTH = Adrenocorticotropic Hormone, CD = Cushing's disease, CS

Cervantes, Lizardi, and the Literary Construction of The Mexican Rogue in Don Catrín de la fachenda

Directory of Open Access Journals (Sweden)

Vilches Patricia

2017-12-01

Full Text Available This study explores the socio-economic legacies and critique of nation-building found in the work of Jose Joaquin Fernandez de Lizardi (1776-1827. In the nineteenth century, the Latin American elite struggled to disassociate itself from a suffocating colonial machine; they sought their own identity, and writing became a way to express their frustration. As in other parts of Latin America, Mexican intellectuals protested fossilisation via Cervantes’s Don Quijote. Using the Spanish author’s text as a blueprint, Lizardi’s Don Catrín de la fachenda depicted a turbulent society that was in the process of abandoning a decaying colonial order. Don Quijote’s characters engaged in power struggles and were involved in a variety of forms of social antagonism. Lizardi juxtaposed and superimposed these on an American geographical and socio-economic space where there was much dissension around the nation’s direction. The social and economic rules of Mexico (and Latin America today can be said to be already present in the social exchanges in Don Catrín. It was in this context that Don Quijote was “Mexicanised” by Lizardi and thereby made to participate in local reflections on liberty, patriotism, capitalism, and citizenship. Cervantes’s text thus took on a socio-political meaning in the narrative of Latin America’s past and present.

Full Text Available Los viajes de Gulliver, de Jonathan Swift, es una de las obras más conocidas de la literatura universal. Sin embargo, su recepción actual, al menos en España, se produce sobre todo por medio de adaptaciones en las que no se puede apreciar el calado de la obra literaria original. En este estudio se pretende profundizar en el análisis de Los viajes de Gulliver a través de una comparación con Don Quijote, enfocándose en los recursos paródicos: mientras Don Quijote parodia los libros de caballerías, Los viajes de Gulliver parodia los libros de viajes. El principal objetivo de esta comparación no será tanto demostrar una influencia de la obra de Cervantes sobre la de Swift, sino, más bien, iluminar algunos aspectos de Los viajes de Gulliver. Gulliver´s Travels, of Jonathan Swift, is one of the most well-known works in world literature. However, its actual reception, at least in Spain, it´s produced mostly through adaptations in which it´s impossible to appreciate the profundity of the original literary work. In this article, I intend to dig deeply into the analysis of Gulliver´s Travels through a comparison with Don Quixote, focusing on the parodic resources: while Don Quixote parodies the books of chivalry, Gulliver´s Travels parodies travel books. The main goal of this comparison will not be to prove some influence of Cervantes´ work in Swift´s work, but to illuminate some aspects of Gulliver´s Travels.

We don't need another hero.

Badaracco, J L

2001-09-01

Everybody loves the stories of heroes like Martin Luther King, Jr., Mother Teresa, and Gandhi. But the heroic model of moral leadership usually doesn't work in the corporate world. Modesty and restraint are largely responsible for the achievements of the most effective moral leaders in business. The author, a specialist in business ethics, says the quiet leaders he has studied follow four basic rules in meeting ethical challenges and making decisions. The rules constitute an important resource for executives who want to encourage the development of such leaders among their middle managers. The first rule is "Put things off till tomorrow." The passage of time allows turbulent waters to calm and lets leaders' moral instincts emerge. "Pick your battles" means that quiet leaders don't waste political capital on fights they can't win; they save it for occasions when they really want to fight. "Bend the rules, don't break them" sounds easier than it is--bending the rules in order to resolve a complicated situation requires imagination, discipline, restraint, flexibility, and entrepreneurship. The fourth rule, "Find a compromise," reflects the author's finding that quiet leaders try not to see situations as polarized tests of ethical principles. These individuals work hard to craft compromises that are "good enough"--responsible and workable enough--to satisfy themselves, their companies, and their customers. The vast majority of difficult problems are solved through the consistent striving of people working far from the limelight. Their quiet approach to leadership doesn't inspire, thrill, or provide story lines for uplifting TV shows. But the unglamorous efforts of quiet leaders make a tremendous difference every day in the corporate world.

Deoxynivalenol (DON) is toxic to human colonic, lung and monocytic cell lines, but does not increase the IgE response in a mouse model for allergy

International Nuclear Information System (INIS)

Instanes, Christine; Hetland, Geir

2004-01-01

We examined whether the common crop mycotoxin deoxynivalenol (DON) from Fusarium species is toxic to human colonic (Caco-2), lung (A549) and monocytic (U937) cell lines. Moreover, since DON reportedly induces increased levels of Th2 cytokines and total IgE, and we have observed that mould extracts adjuvated allergy development in mice, possible adjuvant effect of DON on allergy was studied in a mouse model. For all the cells, exposure to DON for 24 h reduced cellular protein synthesis, proliferation and survival rate dose-dependently. In addition, production of IL-8 in the U937 cell line increased up to eight-fold at levels of DON just lower than the most toxic one, suggesting that IL-8 can be used as an additional index for cytotoxicity in mononuclear phagocytes. However, DON did not increase levels of allergen-specific IgE or IgG1 in the mouse model for allergy. These results suggest that DON, when inhaled or ingested, may have toxic effect on human alveolar macrophages and epithelial cells in lungs and colon, but does not increase the allergic response to allergens

Sources of reactive nitrogen in marine aerosol over the Northwest Pacific Ocean in spring

Atmospheric deposition of long-range transport of anthropogenic reactive nitrogen (Nr, mainly comprised of NHx, NOy and water-soluble organic nitrogen, WSON) from continents may have profound impact on marine biogeochemistry. In addition, surface ocean dissolved organic nitrogen (DON) may also contribute to aerosol WSON in the overlying atmosphere. Despite the importance of off-continent dispersion and Nr interactions at the atmosphere-ocean boundary, our knowledge of the sources of various nitrogen species in the atmosphere over the open ocean remains limited due to insufficient observations. We conducted two cruises in the spring of 2014 and 2015 from the coast of China through the East China seas (ECSs, i.e. the Yellow Sea and East China Sea) to the open ocean (i.e. the Northwest Pacific Ocean, NWPO). Concentrations of water-soluble total nitrogen (WSTN), NO3- and NH4+, as well as the δ15N of WSTN and NO3- in marine aerosol, were measured during both cruises. In the spring of 2015, we also analysed the concentrations and δ15N of NO3- and the DON of surface seawater (SSW; at a depth of 5 m) along the cruise track. Aerosol NO3-, NH4+ and WSON decreased logarithmically (1-2 orders of magnitude) with distance from the shore, reflecting strong anthropogenic emission sources of NO3-, NH4+ and WSON in China. Average aerosol NO3- and NH4+ concentrations were significantly higher in 2014 (even in the remote NWOP) than in 2015 due to the stronger wind field in 2014, underscoring the role of the Asian winter monsoon in the seaward transport of anthropogenic NO3- and NH4+. However, the background aerosol WSON over the NWPO in 2015 (13.3 ± 8.5 nmol m-3) was similar to that in 2014 (12.2 ± 6.3 nmol m-3), suggesting an additional non-anthropogenic WSON source in the open ocean. Obviously, marine DON emissions should be considered in model and field assessments of net atmospheric WSON deposition in the open ocean. This study contributes information on parallel isotopic

Full Text Available Fumonisins are Fusarium mycotoxins that occur in corn and corn-based foods and they have been implicated in several animal and human diseases. Their effect on human health is unclear, however, fumonisins are considered to be risk factors for cancer. Baking, frying, and extrusion cooking of corn at high temperatures (190°C reduce fumonisin concentrations in foods, with the amount of reduction achieved depending on cooking time, temperature, recipe, and other factors. The aim of this work was to evaluate the effectiveness of temperature (200 and 220 °C and time (15 and 20 min on the detoxification of corn flour deliberately contaminated with DON and ZON. After processing at 200°C for 15 min, an average of 12% and after 20 min an average of 15% of DON was lost. At 200°C ZON content was reduced by 22% (after 15 min and by 27% (after 20 min. Higher temperature (220°C did not significantly affect further reduction of DON or ZON content. The process was only partially effective in both cases.

To constrain sources of anthropogenic nitrogen (N) deposition is critical for effective reduction of reactive N emissions and better evaluation of N deposition effects. This study measured δ 15 N signatures of nitrate (NO 3 - ), ammonium (NH 4 + ) and total dissolved N (TDN) in precipitation at Guiyang, southwestern China and estimated contributions of dominant N sources using a Bayesian isotope mixing model. For NO 3 - , the contribution of non-fossil N oxides (NO x , mainly from biomass burning (24 ± 12%) and microbial N cycle (26 ± 5%)) equals that of fossil NO x , to which vehicle exhausts (31 ± 19%) contributed more than coal combustion (19 ± 9%). For NH 4 + , ammonia (NH 3 ) from volatilization sources (mainly animal wastes (22 ± 12%) and fertilizers (22 ± 10%)) contributed less than NH 3 from combustion sources (mainly biomass burning (17 ± 8%), vehicle exhausts (19 ± 11%) and coal combustions (19 ± 12%)). Dissolved organic N (DON) accounted for 41% in precipitation TDN deposition during the study period. Precipitation DON had higher δ 15 N values in cooler months (13.1‰) than in warmer months (-7.0‰), indicating the dominance of primary and secondary ON sources, respectively. These results newly underscored the importance of non-fossil NO x , fossil NH 3 and organic N in precipitation N inputs of urban environments. Copyright © 2017 Elsevier Ltd. All rights reserved.

Informal sources of supervision in clinical training.

Farber, Barry A; Hazanov, Valery

2014-11-01

Although formal, assigned supervision is a potent source of learning and guidance for psychotherapy trainees, many beginning psychotherapists use other, informal sources of supervision or consultation for advice and support. Results of an online survey of beginning trainees (N = 146) indicate that other than their formally assigned supervisor, trainees most often consult with colleagues in their program, their own psychotherapist, and their significant other; that they're most likely to seek these other sources of help when they're feeling stuck or feel they've made a clinical mistake; that they do so because they need extra reassurance and suggestions; that they feel the advice given from these sources is helpful; and that they don't especially regret sharing this information. Several case examples are used to illustrate these points. Discussing clinical material with informal sources is, apparently, a great deal more common than typically acknowledged, and as such, has implications for training programs (including discussions of ethics) and formal supervision. © 2014 Wiley Periodicals, Inc.

'Don't play the butter notes': jazz in medical education.

Science.gov (United States)

Bradner, Melissa; Harper, Darryl V; Ryan, Mark H; Vanderbilt, Allison A

2016-01-01

Jazz has influenced world music and culture globally - attesting to its universal truths of surviving, enduring, and triumphing over tragedy. This begs the question, what can we glean in medical education from this philosophy of jazz mentoring? Despite our training to understand disease and illness in branching logic diagrams, the human experience of illness is still best understood when told as a story. Stories like music have tempos, pauses, and silences. Often they are not linear but wrap around the past, future, and back to the present, frustrating the novice and the experienced clinician in documenting the history of present illness. The first mentoring lesson Hancock discusses is from a time he felt stuck with his playing - his sound was routine. Miles Davis told him in a low husky murmur, 'Don't play the butter notes'. In medical education, 'don't play the butter notes' suggests not undervaluing the metacognition and reflective aspects of medical training that need to be fostered during the early years of clinical teaching years.

The first theatrical adaptations of the Don Quixote and the beginning of Cervantes

Directory of Open Access Journals (Sweden)

Carmen Rivero Iglesias

2012-12-01

Full Text Available The present study analyzes the first appearances of Don Quixote on German stages. The goal is to illustrate how these theatrical performances determine the reception of Cervantes’ work in 17th century Germany. The first performances in Heidelberg (1613 and Dessau (1614 display an interpretation of Don Quixote, which intensifies the grotesque dimension of Cervantes’ original. Its satire is transformed into a satire of Spain in a context determined by political and religious animosity between Catholics and Protestants. The first German translation inherited this conception of Cervantes’ work. This conception would acquire new shades until middle of the 18th century, when the alteration of historical coordinates and the rise of individuality and genius thoroughly transformed its interpretation.

The National Assessment of Educational Progress Science Assessment has consistently revealed small gender differences on science content items but not on science inquiry items. This assessment differs from others in that respondents can choose I don't know rather than guessing. This paper examines explanations for the gender differences including (a) differential prior instruction, (b) differential response to uncertainty and use of the I don't know response, (c) differential response to figurally presented items, and (d) different attitudes towards science. Of these possible explanations, the first two received support. Females are more likely to use the I don't know response, especially for items with physical science content or masculine themes such as football. To ameliorate this situation we need more effective science instruction and more gender-neutral assessment items.

Is the Partner the Don Quixote of the 21st Century Corporate World?

A large and growing proportion of the organizations in the contemporary knowledge economy are organized as professional partnerships as is the case of professional service firms (PSFs). As these firms have grown larger (e. g. Big4: Deloitte, PwC, E&Y, KPMG), the way of organizing is under pressure...... for change. This raises the question of whether the Partner ownership and management model is a relic of the past - and the partner a Don Quixote-figure of the 21st century corporate world? Based on an ethnographic study of a PSF in Denmark, and data from other sources, the paper analyzes the changing...... organization of work, the changing partner and manager roles and basic changes in the HR-model. The dilemma the paper highlights is the tension between a still more centralized and efficiency oriented management and the basic need for development of professional human resources and leadership.

Full Text Available Background: Combretum albidum Don belonging to family Combretaceae is an unexplored medicinal plant in the Indian medicinal system. According to ethnobotanical information, the leaves are used in the treatment of peptic ulcer and its fruits are used in diarrhoea and dysentery. Stem bark is used in the treatment of jaundice and skin diseases. The problem encountered in standardisation of this medicinal plant is its identification by source. Materials and Methods: The pharmacognostical studies were carried out in terms of organoleptic, macroscopic, microscopic, physicochemical, florescence and phytochemical analysis. Physicochemical parameters such as total ash, moisture content and extractive values are determined by World Health Organization guidelines. The microscopic features of leaf components are observed with Nikon lab photo device with microscopic units. Results: Macroscopically, the leaves are simple, obovate in shape, acuminate apex, entire margin and smooth surface. Microscopically, the leaves showed a large vascular strand that consists of thick walled xylem elements mixed with xylem fibres and phloem which is present in a thin layer along inner and outer portions of xylem. External to the xylem occur a thin line of sclerenchyma. Powder microscopy revealed glandular trichomes in the adaxial epidermal peelings also shows the non-glandular trichomes fairly common in powder and epidermis with anisocytic stomata. Vessels elements are narrow, long, cylindrical and dense multi-seriate bordered pits. Xylem fibres are thin and long, with thick walls, which are lignified. Preliminary phytochemical screening showed the presence of carbohydrate, glycoside, saponin, flavonoid, phytosterols and phenolic compounds. Conclusions: The results of the study can serve as a valuable source of pharmacognostic information as suitable standards for identification of this plant material in future investigations and applications.

Fish migration through the deep-water channel in the San Joaquin River at Stockton, California is inhibited by low oxygen concentrations during the summer months. The cause for this condition appears to be stagnation and decomposition of algae with attendant oxygen consumption. Algae growth in the San Joaquin River is promoted by nutrients entering the river mainly in the form of nitrate. Possible significant sources of nitrate include soil, fertilizer from agriculture, manure from dairy operations, and N derived from municipal sewage. A 2000 CALFED pilot study investigated the sources and cycling of nitrate at four sites along the San Joaquin River upstream of Stockton using the carbon and nitrogen isotopes of total dissolved and particulate organic matter, together with hydrological measurements and various concentration data, including chlorophyll-a. The nitrate source, its relationship to phytoplankton, and the effect of the nitrate source and cycling on the N isotopic composition of dissolved and particulate organic matter were the primary concerns of the study. The d15N values of dissolved organic nitrogen (DON) were used as a proxy for nitrate d15N because nitrate comprised about 90% of DON. Chlorophyll-a and C:N ratios indicated that the particulate organic matter (POM) consisted largely of plankton and therefore the d15N of POM was used as a proxy for the d15N of plankton. A tentative interpretation of the pilot study was that nitrate was a major nutrient for the plankton and the nitrate was of anthropogenic origin, possibly sewage or animal waste. To test these assumptions and interpretations, we are currently analyzing a set of samples collected in 2001. In addition to the previous sample types, a subset of samples will be measured directly for nitrate d15N to assess the validity of using d15N of DON as a proxy for nitrate.

Full Text Available Plant productivity is the important indicator, which determines the amount of yield. The productivity of plants depends on the number of bruchids per plant and on the weight of 1000 bruchids. The article studies the influence of impulse pressure of various magnitudes on plant productivity of Don barley (Hordeum vulgare L.. It was found that the pressure of 17 MPa was the most effective for increasing the productivity. Impulse pressure of other magnitudes also had influence on the productivity of Don barley.

Sealed radioactive source management

International Nuclear Information System (INIS)

2005-01-01

Sealed radioactive sources have been used in a wide range of application in medicine, agriculture, geology, industry and other fields. Since its utilization many sources have become out of use and became waste but no proper management. This has lead to many accidents causing deaths and serious radiation injuries worldwide. Spent sources application is expanding but their management has seen little improvements. Sealed radioactive sources have become a security risk calling for prompt action. Source management helps to maintain sources in a good physical status and provide means of source tracking and control. It also provides a well documented process of the sources making any future management options safe, secure and cost effective. Last but not least good source management substantially reduces the risk of accidents and eliminates the risk of malicious use. The International Atomic Energy Agency assists Member States to build the infrastructure to properly manage sealed radioactive sources. The assistance includes training of national experts to handle, condition and properly store the sources. For Member States that do not have proper facilities, we provide the technical assistance to design a proper facility to properly manage the radioactive sources and provide for their proper storage. For Member States that need to condition their sources properly but don't have the required infrastructure we provide direct assistance to physically help them with source recovery and provide an international expert team to properly condition their sources and render them safe and secure. We offer software (Radioactive Waste Management Registry) to properly keep a complete record on the sources and provide for efficient tracking. This also helps with proper planning and decision making for long term management

Two poorly known species of geophilid centipedes from the Andes of South-Central Chile, i.e., Plateurytion mundus (Chamberlin, 1955) and Plateurytion zapallar (Chamberlin, 1955) (Myriapoda: Chilopoda: Geophilomorpha), are herein redescribed and illustrated after type specimens of both taxa and new material of the latter, rectifying the condition of the coxosternites of the second maxillae, which are medially joined through a narrow, hyaline and non-areolate membranous isthmus only (instead of "broadly fused as in Pachymerium", as stated by Chamberlin), this being consistent with the current generic assignment of these species under Plateurytion Attems, 1909. New data on many morphological features of specific value, until now unknown, are also given for both taxa. Plateurytion zapallar is reported for the first time from Coquimbo region, 11 Km N of Los Vilos (Elqui province), Valparaíso region, Quebrada Huaquén, Pichicuy (Petorca province), La Campana National Park (Quillota province), and Quebrada el Tigre, Cachagua (Valparíso province). A key for identification of the South American species currently included in Plateurytion is given.

Sources of reactive nitrogen in marine aerosol over the Northwest Pacific Ocean in spring

Full Text Available Atmospheric deposition of long-range transport of anthropogenic reactive nitrogen (Nr, mainly comprised of NHx, NOy and water-soluble organic nitrogen, WSON from continents may have profound impact on marine biogeochemistry. In addition, surface ocean dissolved organic nitrogen (DON may also contribute to aerosol WSON in the overlying atmosphere. Despite the importance of off-continent dispersion and Nr interactions at the atmosphere–ocean boundary, our knowledge of the sources of various nitrogen species in the atmosphere over the open ocean remains limited due to insufficient observations. We conducted two cruises in the spring of 2014 and 2015 from the coast of China through the East China seas (ECSs, i.e. the Yellow Sea and East China Sea to the open ocean (i.e. the Northwest Pacific Ocean, NWPO. Concentrations of water-soluble total nitrogen (WSTN, NO3− and NH4+, as well as the δ15N of WSTN and NO3− in marine aerosol, were measured during both cruises. In the spring of 2015, we also analysed the concentrations and δ15N of NO3− and the DON of surface seawater (SSW; at a depth of 5 m along the cruise track. Aerosol NO3−, NH4+ and WSON decreased logarithmically (1–2 orders of magnitude with distance from the shore, reflecting strong anthropogenic emission sources of NO3−, NH4+ and WSON in China. Average aerosol NO3− and NH4+ concentrations were significantly higher in 2014 (even in the remote NWOP than in 2015 due to the stronger wind field in 2014, underscoring the role of the Asian winter monsoon in the seaward transport of anthropogenic NO3− and NH4+. However, the background aerosol WSON over the NWPO in 2015 (13.3 ± 8.5 nmol m−3 was similar to that in 2014 (12.2 ± 6.3 nmol m−3, suggesting an additional non-anthropogenic WSON source in the open ocean. Obviously, marine DON emissions should be considered in model and field assessments of net atmospheric WSON deposition in the open ocean. This

For the Amusement of the Merry Little Subjects: How British Children Met Don Quixote in the Long Eighteenth Century

Miriam Borham Puyal

2015-12-01

Full Text Available As a masterpiece, Don Quixote has become an easily recognizable myth, sometimes reduced to well-known episodes such as the tilting at windmills or the blanket-tossing of Sancho. These elements are emphasised in editions of this classic for children, highlighting the importance these versions have for the understanding of the widespread popularity of Cervantes’ novel, in general, and of certain scenes, in particular. The present article explores the relationship of the child reader to Don Quixote and provides an overview of how English children might have encountered it in the long eighteenth century (1660-1832. It connects chapbooks, abridgments and children’s books to suggest that children might have been among its earliest readers and to emphasise the intertextual continuum and the richness in the reception of Don Quixote in England, from the seventeenth to the nineteenth century.

This chronicle is unique high temporal coverage, from 1873 to 1929, it includes the years of revolution, Civil war on the Don and the first post-revolutionary decade. The author gives a brief overview of the history of the chronicle, the characteristics of its six authors — rural priests. The first thirty years were marked by the construction and decoration of the church and the absence of conflict. The early twentieth century was marked by the confl icts of the parishioners with the clergy. In the chronicle it was described the hardships of the lives of ordinary Cossacks, the scourge of Civil war, the famine of the early 1920s. In the postwar years there has been growing discontent of the parishioners by the activities of the Soviet government: tax policy, anti-religious propaganda and oppression of the clergy, beginning with collectivization. Narratives are rural priests, and it refl ects their own perception of the key events of the age. The author in the article examines the attitude of the parishioners to the Church, their perception of current events, participation in parish life. He concludes on a high degree of involvement of Cossacks in the Church life, the importance of the Church in their daily lives. The facts given in the article, suggest the sustainability of the parish farm, the community was able to survive in the turmoil of the Civil war. Forced destruction of parish life in the years of collectivization destroyed the community and has led to the degradation and disappearance of rural settlement. The last author of the chronicle was repressed, he and those arrested with him the clergy and parishioners were accused of preparing an armed uprising. The chronicle shows that this

Se asocia a la admiración y al orgullo que este hombre despierta por su inteligencia, su sabiduría y su obra entre sus gentes de España, con el entrañable afecto que su nombre evoca entre nosotros los iberoamericanos que también, a nuestra manera, lo sentimos nuestro.

Médico, historiador, escritor, humanista, sociólogo y maestro, su espíritu se ensoñoreó por los campos abiertos del saber, descollando con méritos señeros en cada una de estas disciplinas. Y si en el presente siglo su par en la medicina podría ser don Santiago Ramón y Cajal, en las letras don José Ortega y Gassety en las humanidades don Miguel de Unamuno, por su bucear en las aguas profundas y lustrales de la historia su nombre es parangonable con el de españoles eternos con los que equiparó su vida: un Séneca, por su austero interrogar al destino y por el doloroso regustar del destierro (“carere patria intolerabili est”.

Un Maimónides, por las enseñanzas de su saber médico y por los discípulos dejados en las más diversas latitudes unido a su excepcional amplitud de criterio -rara flor en la patria de Ignacio de Loyolay de don Felipe 11-; ausencia de ese dogmatismo y fanatismo que el mismo “espejo de los caballeros” hubo de sublimar en las brumas de su locura para ser el arquetipo de lo español y de España.

The formal collapse of the Soviet Union at the end of 1991 produced major socio-economic and institutional dislocations across the agricultural sector. The picture of broad scale patterns produced by these transformations continues to be discovered. We examine here the patterns of land surface phenology (LSP) within two key river basins-Don and Dnieper-using AVHRR (Advanced Very High Resolution Radiometer) data from 1982 to 2000 and MODIS (Moderate Resolution Imaging Spectroradiometer) data from 2001 to 2007. We report on the temporal persistence and change of LSPs as summarized by seasonal integration of NDVI (normalized difference vegetation index) time series using accumulated growing degree-days (GDDI NDVI). Three land cover super-classes-forest lands, agricultural lands, and shrub lands-constitute 96% of the land area within the basins. All three in both basins exhibit unidirectional increases in AVHRR GDDI NDVI between the Soviet and post-Soviet epochs. During the MODIS era (2001-2007), different socio-economic trajectories in Ukraine and Russia appear to have led to divergences in the LSPs of the agricultural lands in the two basins. Interannual variation in the shrub lands of the Don river basin has increased since 2000. This is due in part to the better signal-to-noise ratio of the MODIS sensor, but may also be due to a regional drought affecting the Don basin more than the Dnieper basin.

The silent Don Juan. The concepts of love and art in the works of Max Frisch

Directory of Open Access Journals (Sweden)

Špela Virant

2012-07-01

Full Text Available In the novel Stiller and in the play Don Juan, both published in the early 1950s, Frisch already focuses on the problem of identity as one of his major themes, but it is not yet situated in a political context as, for example, in the play Andorra. In these works, the identity-problem is situated in the domain of intimate relationships and artistic creativity, offering the possibility to discuss Frisch’s concepts of art and love, which unfold through Frisch’s treatment of the traditional literary figure of Don Juan and his hubris. Frisch’s Stiller and Don Juan do not believe in God; but their frame of mind stays the same, while the position of God and his attributes are assigned to love, art and geometry. Although both literary figures in the course of events realize that this substitution is a mistake, they are unable to alter their concepts of love and art. Instead of altering the concepts, they rather resign in silence, while Max Frisch continues to search for alternatives in reflecting on the process of fictionalization and in developing innovative narrative and dramatic structures.

Résumé Ces recommandations sont le fruit d'un processus multidisciplinaire national ayant duré un an et visant à déterminer si et comment l'on pourrait procéder au don d'organes après un décès d'origine cardiocirculatoire («don après le décès cardiocirculatoire», ou DDC) au Canada. Le forum national organisé en février 2005 a permis aux participants de discuter et d'élaborer des recommandations sur les principes, interventions et pratiques se rapportant au DDC. Les aspects éthiques et juridiques ont été abordés dans les discussions. À la fin du Forum, la majorité des participants ont été favorables à l'implantation de programmes de DDC au Canada. Les participants du Forum ont également convenu qu'il fallait formuler et prôner des valeurs fondamentales pour orienter l'élaboration de programmes et de protocoles basés sur le cadre médical, éthique et juridique établi lors de cette réunion. Même si la possibilité d'un don d'organes et de tissus doit faire partie intégrante des soins de fin de vie, il faut insister sur le fait que le devoir de diligence envers les patients mourants et leurs familles doit demeurer la priorité des équipes soignantes. La complexité et les répercussions profondes du décès sont reconnues et doivent être respectées, de même que les différences personnelles, ethnoculturelles et religieuses face à la mort et au don d'organes. Les décisions d'arrêter le traitement de maintien des fonctions vitales, la prise en charge des derniers moments de la vie et le diagnostic de décès selon des critères cardiocirculatoires doivent être distincts et indépendants des processus de don et transplantation. Ce rapport contient des recommandations destinées aux gestionnaires de program, aux autorités sanitaires régionales et aux instances appelés à élaborer les protocoles de DDC.

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

Daya Bay in the South China Sea (SCS) has experienced rapid nitrogen pollution and intensified eutrophication in the past decade due to economic development. Here, we estimated the deposition fluxes of nitrogenous species, clarified the contribution of nitrogen from precipitation and measured ions and isotopic composition (δ15N and δ18O) of nitrate in precipitation in one year period to trace its sources and formation processes among different seasons. We found that the deposition fluxes of total dissolved nitrogen (TDN), NO3-, NH4+, NO2-, and dissolved organic nitrogen (DON) to Daya Bay were 132.5, 64.4 17.5, 1.0, 49.6 mmol m-2•yr-1, respectively. DON was a significant contributor to nitrogen deposition (37% of TDN), and NO3- accounted for 78% of the DIN in precipitation. The nitrogen deposition fluxes were higher in spring and summer, and lower in winter. Nitrogen from precipitation contributed nearly 38% of the total input of nitrogen (point sources input and dry and wet deposition) in Daya Bay. The δ15N-NO3- abundance, ion compositions, and air mass backward trajectories implicated that coal combustion, vehicle exhausts, and dust from mainland China delivered by northeast monsoon were the main sources in winter, while fossil fuel combustion (coal combustion and vehicle exhausts) and dust from PRD and southeast Asia transported by southwest monsoon were the main sources in spring; marine sources, vehicle exhausts and lightning could be the potential sources in summer. δ18O results showed that OH pathway was dominant in the chemical formation process of nitrate in summer, while N2O5+ DMS/HC pathways in winter and spring.

NASA aircraft technician Don Herman completes placement of the first official U.S. Centennial of Flight Commission logo on an aircraft. The honored recipient is NASA Dryden Flight Research Center's Active Aeroelastic Wing (AAW) F/A-18 research aircraft, which is poised to begin wing-warping research flights harkening back to the Wright brothers. The Centennial of Flight Commission was created by the U.S.Congress in 1999 to serve as a national and international source of information about activities to commemorate the centennial of the Wright Brothers' first powered flight on the sands of Kitty Hawk, North Carolina, on December 17, 1903. Centennial activities are scheduled for 2003 in both North Carolina and Dayton, Ohio, home of the Wrights. In addition to these celebrations, numerous historical and educational projects are anticipated on the subject of aviation and aeronautics that will be an important legacy of the centennial of powered flight.

A neural model for transient identification in dynamic processes with 'don't know' response

International Nuclear Information System (INIS)

Mol, Antonio C. de A.; Martinez, Aquilino S.; Schirru, Roberto

2003-01-01

This work presents an approach for neural network based transient identification which allows either dynamic identification or a 'don't know' response. The approach uses two 'jump' multilayer neural networks (NN) trained with the backpropagation algorithm. The 'jump' network is used because it is useful to dealing with very complex patterns, which is the case of the space of the state variables during some abnormal events. The first one is responsible for the dynamic identification. This NN uses, as input, a short set (in a moving time window) of recent measurements of each variable avoiding the necessity of using starting events. The other one is used to validate the instantaneous identification (from the first net) through the validation of each variable. This net is responsible for allowing the system to provide a 'don't know' response. In order to validate the method, a Nuclear Power Plant (NPP) transient identification problem comprising 15 postulated accidents, simulated for a pressurized water reactor (PWR), was proposed in the validation process it has been considered noisy data in order to evaluate the method robustness. Obtained results reveal the ability of the method in dealing with both dynamic identification of transients and correct 'don't know' response. Another important point studied in this work is that the system has shown to be independent of a trigger signal which indicates the beginning of the transient, thus making it robust in relation to this limitation

La lepra es una enfermedad que se caracteriza por la insidia de su presencia, su lenta evolución y la progresiva incapacidad que en sus víctimas causa.

Esto y el temor que ha infundido desde tiempos bíblicos, han hecho que ante ella se haya mantenido una actitud ambivalente de negación hasta donde es posible y de rechazo irracional a quien la padece, por temor al contagio.

Ejemplo de ello es el aura de sagrado misterio que envuelve la leyenda de los padecimientos del Adelantado don Gonzalo Jiménez de Quesada (1509-1579, conquistador del Nuevo Reino de Granada y fundador de Santafé de Bogotá en el año de 1538, muerto a la edad, avanzada para la época, de setenta años.

No se puede afirmar, en forma definitiva, que el conquistador fuera leproso. Se acepta, acogiendo el argumento de autoridad que tiene el primer historiador médico entre nosotros, don Pedro María Ibáñez, quien escribió en 1884, en las Memorias para la Historia de la Medicina en Santa Fe, que en “1579 falleció en la ciudad de Mariquita, y de mal de lepra o elefancía de los

Full Text Available From an artistic point of view, the adaptation of an opera to the cinema, traditionally has been considered a complex and controversial process. Don Giovanni, of W.A. Mozart is one of the operas that more audiovisual versions has generated during the centuries XX and XXI, although very few films have finally been taken to the screen. This paper is focused on comparing the audiovisual versions Don Giovanni, by Joseph Losey (1979, and Juan by Kasper Holten (2010. Through a quantitative and qualitative methodology based on content analysis, this research reflects on the degree of intervention exercised by the language and audiovisual format used in the process of reinterpretation of the pre-existing operatic text.

Don Quixote, Machiavelli, and Robin Hood: public health practice, past and present.

Science.gov (United States)

Mullan, F

2000-05-01

Since the mid-19th century, when the first formal health departments were established in the United States, commissioners, directors, and secretaries of public health have functioned as senior members of the staffs of public executives, mayors, governors, and presidents. They have provided important political, managerial, and scientific leadership to agencies of government that have played increasingly important roles in national life, from the sanitary revolution of the 19th century to the prevention of HIV/AIDS and the control of tobacco use today. Although public health officials come from a variety of backgrounds and oversee agencies of varied size and composition, there are philosophical themes that describe and define the commonality of their work. These themes are captured metaphorically by 3 celebrated figures: Don Quixote, Machiavelli, and Robin Hood. By turns, the public health official functions as a determined idealist (Don Quixote), a cunning political strategist (Machiavelli), and an agent who redistributes resources from the wealthier sectors of society to the less well off (Robin Hood.) All 3 personae are important, but, it is argued, Robin Hood is the most endangered.

Signs of revision in Don Quixote, Part II

Gonzalo Pontón

2016-11-01

Full Text Available This article provides new evidences in favour of the hypothesis that Cervantes, after finishing Don Quixote, Part II, partially revised the original, introducing some significant changes and additions, mainly in the last chapters. The analysis of some narrative inconsistencies, that cannot be interpreted as mere mistakes but as significant textual traces, reveals a process of re-elaboration –a process that affects at least four sections of the novel. Most of the evidence gathered here suggests that this revision is closely linked to Avellaneda’s continuation, in the sense that Cervantes tried to challenge the apocriphal Quixote making last-time interventions in his own text.

The feature follows the Sanchification of Jerry (Jack Black, Gondry’s Don Quixote, and Quixotification of Mike (Mos Def, Gondry’s Sancho, as they nostalgically wrong cinematic rights through sweding and try to save their working-class neighbourhood from condemnation and gentrification through community film making.

This article discusses Be Kind Rewind’s relationship to Hollywoodian and Cervantine classics through the theoretical frameworks of Julio Garcia Espinosa’s imperfect cinema and Foucauldian semiotics, respectively. Be Kind Rewind uses and abuses Hollywood stereotypes to re-purpose them for a critique of discriminatory practices. Where casting is concerned and where Michel’s characters diverge from Miguel’s, Be Kind Rewind advances that skin colour is not an arbitrary sign and that race has historical and contemporary meaning in intercultural interactions.

Full Text Available Il mito letterario di don Giovanni, sorto nella commedia, attorno al 1800 viene riformulato in direzione del tragico. La trasformazione inizia con la versione operistica di Mozart-Da Ponte e trova compimento nel racconto di Hoffmann, che proietta il nuovo tono tragico del finale mozartiano su tutto il mito. L’articolo intende porre in rilievo la presenza nel Don Juan di numerosi richiami intertestuali al Faust di Goethe, finora non pienamente rilevati dalla critica, attraverso i quali è possibile leggere tale riscrittura tragica come una dichiarata sintesi dei due miti, in cui don Giovanni assume il ruolo di Faust-Mefistofele e donna Anna quello di Gretchen. La riscrittura del mito culmina nel finale rispecchiamento del narratore in Anna-Gretchen. Ma il valore del tragico è relativizzato in Hoffmann dall’ironica autocoscienza dell’artista romantico: confinato nel mondo fantastico dell’arte, risulta privo di senso nella prosaica realtà della vita borghese.

Scientific Communication for Positive Action: Do's and Don'ts

Science.gov (United States)

Sanquini, A.; Wood, M. M.

2015-12-01

Natural hazard presentations often highlight disasters that may ensue from natural processes when mitigation or preparedness actions are not taken. Examples include images of raging fires, collapsed buildings, and flooded urban areas. Research has shown that this makes presentations more interesting and more memorable. Such images are the stock and trade of disaster reporting by the media. Unfortunately, it may also trigger avoidance and denial in the audience, resulting in preparedness reduction; the opposite effect of what may have been intended by the speaker. Recent social research has provided insight into a better approach. The theory of communicating actionable risk posits that people will take action against hazards when they know what to do, think it would work, and know someone who did it. This approach was recently applied in an intervention designed to motivate earthquake-resistant construction in Kathmandu Valley, Nepal. Social theory further suggests that a tendency towards action is strengthened by hearing a consistent message over time, and by providing the audience with an appropriate opportunity to seek out relevant information. This presentation shows how, by taking this transdisciplinary step, scientists can make small changes in their hazard communication, thereby acting as positive influencers of change. A summary of "do's" and "don'ts" is given for reference. 1. Show examples of what to do. 2. Show effectiveness of actions. 3. Give sense of knowing someone who did it. 4. Deliver consistent message, repeatedly. 5. Give opportunity for more information. DON'T: 1. Make the disaster the star. 2. Contradict other communications.

Application of ionizing radiation sources to medicine. Civil-legal aspect

Golikov, V.Ya.; Zel'din, A.L.

1990-01-01

Civil-legal aspect of using ionizing radiation sources (IRS) in medicine was investigated. It is shown that IRS are sources of great danger. Application of medical procedures with the use of IRS requires the ofligatory agreement of a patient or his legal representatives. Concealment of doses, received by patients, prohibition of issuing dose cards complicate dose load accounting and are considered as unlawful. Legal evaluation of IRS harmfulness is difficult, because delayed radiation effects are manifested after long periods of time. Application of IRS procedures is lawful when other methods of diagnosis and therapy can't be applied. The use of methods and equipment, which don't result to minimal radiation doses, should be considered as unlawful. Standards, regulating the order of IRS procedures, should be revised

The retirement of radioactive source is a difficult problem that we are facing during the radiation safety regulation in China. This paper analyses the reason of the problem regarding the retirement of radioactive source both from the utilization units and the regulatory body. It is considered that the basic reason is the enterprises don't arrange and use the retirement funds reasonably, which is an economic problem. There exists a limitation when facing the radioactive source retirement in light of licensing and regulation mechanism of the manufacture, selling, uses of radioactive sources in China, and the key to solve this economic problem is to introduce economic method, Some measures and suggestions are given to establish radioactive sources retirement mechanism by using economic methods, based on the comprehensive analysis of the concept, development and function of the environmental liability insurance.

The combined use of chemical and isotopic information to model the effects of stormwater infiltration on groundwater quality in an urban fractured rock aquifer, Auckland, New Zealand

Rosen, M.R.; Hong, Y.S.; Reeves, R.; Sheppard, D.; Roberts, K.; Viljevac, Z.; Smaill, A.

2002-01-01

Disposal of storm water in the Mt Eden area of Auckland, New Zealand, is via 'soak holes' drilled directly into the top of fractured basalt. Although this method of disposal has been used for at least 60 years, its sustainability with respect to groundwater quality has not been addressed. The groundwater has relatively low concentrations of dissolved heavy metals, although total metals are higher suggesting that the metals are bound to mobile particulates within the aquifer. PAH concentrations are also low in the aquifer, although sampling after rainfall events show small increases in PAH. Tritium measurements of the groundwater showed that all of the groundwater south of Chamberlin Park is less than 2 years old. This area has many soak holes. The data suggest that infiltration is very rapid and occurs throughout the area almost simultaneously after rainfall events. One well north of Chamberlin Park, where soak holes are absent has an age of 47 years ± 2 years. The groundwater here is low in dissolved oxygen and appears to be slow moving. CFC measurements indicate that all wells sampled south of Chamberlin Park are contaminated by excess CFCs. However, this result indicates rapid recharge from the surface via storm water. The same well north of Chamberlin Park that was dated using tritium, also has a CFC age of approximately 30 years. Thus, CFC dating may be useful in urban areas that are separated from atmospheric contamination by confining beds or slow circulation. A Kohonen self-organising feature maps (KSOFM) neural network was used to analyse the effect on storm water infiltration on groundwater quality, and determine the inter-relationship of the groundwater quality variables. The model shows that where the land use type is industrial or residential with many soak holes, there is a strong correlation of increased concentrations of heavy metals and storm water infiltration.

This study examined the formation of disinfection by-products (DBPs), including nitrogenous DBPs, haloacetonitriles (HANs), and carbonaceous DBPs, trihalomethanes (THMs), upon chlorination of water samples collected from a conventional Chinese surface water treatment plant (i.e. applying coagulation, sedimentation, and filtration). Reductions in the average concentrations (and range, shown in brackets) of dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) from 4.8 (3.0-7.3) μg/L and 0.52 (0.20-0.81) μg/L in 2010 to 2.4 (1.4-3.7) μg/L and 0.17 (0.11-0.31) μg/L in 2012, respectively, led to a decrease in HANs and THMs from 5.3 and 28.5 μg/L initially to 0.85 and 8.2 μg/L, as average concentrations, respectively. The bromide concentration in the source water also decreased from 2010 to 2012, but the bromine incorporation factor (BIF) for the THMs did not change significantly; however, for HAN the BIFs increased because the reduction in DON was higher than that of bromide. There was good linear relationship between DOC and THM concentrations, but not between DON and HANs. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available The article is devoted to one of the most pressing problems of the history of the ancient Northern Black Sea region: the situation in the Lower Don contact zone in the first centuries CE. Its main peculiarity was the mutual influence of the ancient and barbarian Iranian world on the one hand, and the interaction of the sedentary and nomadic population of the region on the other. In the Lower Don from the first to the third centuries CE, lived three different ethno-cultural groups: the nomads of Sarmatia, the Greeks (inhabitants of Tanais, and the Meotians (in the ancient settlements on the right and left banks of Don. Based on the analysis of archaeological data and written sources, the features of the Lower Don contact zone are presented as a result of evolution in three interconnected planes: economic, ethno-cultural, and political. Attention is paid to the problem of the Tanais and Meotian fortifications, as well as to the identification of specific cultural practices that arisen in the Lower Don contact zone.

Don quijote, Christelike geloof en natuurwetenskap 1

Full Text Available The story about Don Qulchote and the windmills is used in this article as an analogy to typify the debates that have taken place in history between natural science and representatives of Christian religion. The analogy is tested on debates that took place around Galileo. Darwin, Newton, Cuvier and the Big Bang theory. The analogy matches these debates quite well and this Is explained by the view that scientific claims to knowledge, and claims to knowledge based on Christian faith, belong to different categories and are thus not concurrents for the same truth. Gilbert Ryle's criticism on Descartes' mind-body dualism is used here to strengthen this argument. The article is concluded by pointing out in what ways one can engage in a meaningful debate on the nature of the relationship between science and Christian religion.

Full Text Available This study analyses chivalry, materialism, and the grotesque in Alberto Blest Gana’s El ideal de un calavera [The Ideal of a Rogue] (1863 under the light of Miguel de Cervantes’s Don Quijote’s part II (1615. It underscores the legacy of Cervantes on the Chilean author especially in his reflections on nation building. Unlike its author, Don Quijote eluded restriction and successfully reached the colonies; once there, author and text became a massive influence on intellectuals in the burgeoning Americas. Blest Gana, for example, created protagonists who were multi-dimensional and imbued with quixotic overtones. Praised by his counterparts, he created work that was finely detailed, with a goal of portraying the nation’s cultural practices at specifics points in history. Deploying techniques inspired by Honore de Balzac (also a reader of Don Quijote, Blest Gana illustrated the colourful aspects of his society. His sharp eye depicted and interpreted nationhood and society through the course of dramatic historical events in El ideal de un calavera by shining a bright light on the political and social enemies who emerged in the historical unravelling of the nation in the 1830s. The resulting kaleidoscope of astute, idealistic and cowardly individuals conveyed subtle yet definite Cervantesque tones.

Discurso pronunciado por el Doctor Alvaro López Pardo Presidente de la Academia de Historia de Bogotá, al Consejo de Bogotá el día 6 de agosto de 1988. Sesión especial de los 450 años.

Por el año de 1578, caminaba lentamente por las polvorientas calles del poblado de Mariquita, un anciano, casi octogenario, que mostraba en su piel huellas de un enfermedad que se decía era la de San Lázaro.

Las gentes lo miraban pasar con una mezcla de respeto y de piedad. En su mirada, un tanto vaga, se podían apreciar destellos de la que fuera una recia personalidad. Esta pobre figura era nadie menos que el Mariscal Don Gonzalo Jiménez de Quesada.

En esta población ardiente y lejana, cargado de deudas, sin techo propio, iba a morir el gran señor, el Gran Capitán, el Gran Aventurero que fundara ésta nuestra noble y muy leal Santa Fe de Bogotá, cuyos 450 años celebramos en este día.

Parece increíble que en aquella época y con una agitada vida, Don Gonzalo hubiera llegado a tan avanzada edad, es muestra de la fuerza de una raza y del templo de su espíritu, que se sobreponía a todas las adversidades y contratiempos.

¿Qué recuerdos vendrían a la mente de este anciano cuando, sentado en una pobre silla de vaqueta, contempla el azul cielo del trópico? ¿Quizá su infancia en España, en Córdoba, donde naciera o en la imponente Granada de los moros, recuperada hacía unos años por la Reina Isabel. Viendo los jardines de la Alhambra, el Generalife y al fondo el blanco perpetuo de la Sierra Nevada. O vendría a su mente el paso del fúnebre cortejo de Felipe el Hermoso y su lunática viuda Doña Juana?

Sería tal vez el periodo de su juventud, oyendo las aventuras de Cortés en la Conquista de México, en medio de una Europa convulsionada y con España como centro de la misma. O quizás cuando estudiaba leyes en Salamanca y se metía en pleitos que no siempre ganaba y como

Full Text Available The Local Know-how in the Valorisation of (Dacryodes edulis (G. Don H.J. Lam Fruits in Cameroon. Dacryodes edulis (G. Don H.J. Lam (Burseraceae is an oleaginous plant highly appreciated in the forest zone of Cameroon. This tree yields fruits called african pear or safou, highly consumed by local populations and even abroad. African pear is at the centre of a great economic activity in the Central Africa subregion as its trade generates cash for local traders during the production period. However, the valorisation of african pear is hindered by its high perishable nature responsible for important post-harvest losses due to lack of proper post-harvest handling. Some studies addressed the problem, unfortunately, nothing was done on the local know-how which has still to be investigated. The present paper sheds light on african pear local harvesting, handling and marketing practices in Cameroon. Field surveys were carried out in different production zones in Cameroon savannah and humid forest lowlands: Adamawa, centre, east, littoral and west provinces. Results showed that african pear occupies an important place in the population daily life. This multipurpose tree specie appears to be a source of foodstuffs, cash income, drugs and wood. If, on one hand diverse strategies are developed by the population for a proper conservation of fruits, on the other hand there is not a real fruits transformation activity. Results of this study highlight the traditional know-how and bring out prospects for future works on african pear valorisation.

Detection of calmodulin binding protein at 170 KDA in BALB, AKR, DON and chicken granulosa cells

International Nuclear Information System (INIS)

Selinfreund, R.; Lin, P.H.; Marrone, B.; Wharton, W.

1987-01-01

Calmodulin (CAM) has been shown to bind to the epidermal growth factor (EGF) receptor (170 kDa) and is phosphorylated in a EGF dependent manner in the A431 human epidermoid carcinoma cells. In the present study, they report 125 I-CAM binding to a 170 kDa protein detected in cell membrane vesicles of Balb/3T3, AKR, DON and chicken granulosa cells. Purified plasma membranes from these cells were resolved via electrophoresis (without heat denaturation) and electroblotted onto nictrocellulose paper. Upon hybridizing against 125 I-CAM, a distinct autoradiographic band occurred at 170 kDa for all the cells lines under study. The binding of CAM is specific and can be displaced with the addition of excess unlabeled CAM. The result suggest that 125 I-CAM may bind to the 170 kDa EGF receptor in BALB, AKR, DON and chicken granulosa cells

Making decision on not to resuscitate is a confusing, conflicting and complex issue and depends on each country's culture and customs. Therefore, each country needs to take action in accordance with its cultural, ethical, religious and legal contexts to develop guidelines in this regard. Since the majority of Iran's people are Muslims, and in Islam, the human life is considered sacred, based on the values of the community, an Iranian Islamic agenda needs to be developed not taking measures about resuscitation of dying patients. It is necessary to develop an Iranian Islamic guidelines package in order to don't resuscitate in dying patients.

Examining the role of dissolved organic nitrogen in stream ecosystems across biomes and Critical Zone gradients

Watershed nitrogen exports are often dominated by dissolved organic nitrogen (DON); yet, little is known about the role ambient DON plays in ecosystems. As an organic nutrient, DON may serve as either an energy source or as a nutrient source. One hypothesized control on DON is nitrate (NO3-) availability. Here we examine the interaction of NO3- and DON in streams across temperate forests, tropical rainforests, and Mediterranean and taiga biomes. Experimental streams also drain contrasting Critical Zones which provide gradients of vegetation, soil type and lithology (e.g. volcaniclastic, granitic, ultramafic, Siberian Traps Flood Basalt) in which to explore how the architecture of the Critical Zone affects microbial biogeochemical reactions. Streams ranged in background dissolved organic carbon (DOC) concentration (1-50 mg C/L) and DOC: NO3- ratios (10-2000). We performed a series of ecosystem-scale NO3- additions in multiple streams within each environment and measured the change in DON concentration. Results demonstrate that there is considerable temporal and spatial variation across systems with DON both increasing and decreasing in response to NO3- addition. Ecologically this suggests that DON can serve as both a nutrient source and an energy source to aquatic microbial communities. In contrast, DOC concentrations rarely changed in response to NO3- additions suggesting that the N-rich fraction of the ambient dissolved organic matter pool is more bioreactive than the C-rich fraction. Contrasting responses of the DON and DOC pools indicate different mechanisms controlling their respective cycling. It is likely that DON plays a larger role in ecosystems than previously recognized.

Filamentous fungi are cosmopolitan microorganisms found in almost all environments. It should be pointed out that occurance of moulds on food or feed may cause health disorders in humans and animals. Mycoflora appears as a source of toxic methabolites, mycotoxins, which hepatotoxic, genotoxic, nefrotoxic and carcinogenic abilities were already proven in several studies. Hense mycological analysis of cereal grains raises as an important manner in evaluation of food and feed health features. Among the most frequent cereal contaminants Alternaria, Aspergillus, Fusarium and Penicillium strains are mentioned. Due to their ability to grow on cereals during both its field growth and storage, Fusarium moulds occure to be an important contamination factors in food and feed industry. In this study Fusarium strains isolates from wheat and maize were examined in order to recognize their abilities to produce two toxins: zearalenon (ZEA) and deoxynivalenole (DON). Mycological analysis shown differentiation within fungal microflora occuring in samples of different storage conditions, where Fusarium strains represented aproximately 20-70% of all mould species present. In purpose of Fusarium strains species evaluation, isolates were mycologically analysed. In the second step of the project, toxicological screening of isolates was performed using Thin Liquid Chromatography (TLC) evaluating toxigenic potential of single strains' production of ZEA and DON. This data gives the possibility of pointing the most toxigenic strains and also shows differentiations in their occurance in cereals. This paper presents introductory research data, which can be useful in recognition of cereal contamination with moulds and their toxic methabolites.

A possibilistic approach for transient identification with 'don't know' response capability optimized by genetic algorithm

International Nuclear Information System (INIS)

Almeida, Jose Carlos S. de; Schirru, Roberto; Pereira, Claudio M.N.A.; Universidade Federal, Rio de Janeiro, RJ

2002-01-01

This work describes a possibilistic approach for transient identification based on the minimum centroids set method, proposed in previous work, optimized by genetic algorithm. The idea behind this method is to split the complex classification problem into small and simple ones, so that the performance in the classification can be increased. In order to accomplish that, a genetic algorithm is used to learn, from realistic simulated data, the optimized time partitions, which the robustness and correctness in the classification are maximized. The use of a possibilistic classification approach propitiates natural and consistent classification rules, leading naturally to a good heuristic to handle the 'don't know 'response, in case of unrecognized transient, which is fairly desirable in transient classification systems where safety is critical. Application of the proposed approach to a nuclear transient indentification problem reveals good capability of the genetic algorithm in learning optimized possibilistic classification rules for efficient diagnosis including 'don't know' response. Obtained results are shown and commented. (author)

You Don't Look Like a Physicist

"You don't look like a physicist!" "Sorry, this bus only goes to the university, Sir." "Where are you going, sir?" "So, you are a university professor? But a substitute one, aren't you?" "OK, you're a professor, but do you do research?" As a person of color teaching physics in Brazil, those are some comments that I usually hear. They are consequences of stereotypes, prejudices, and discrimination, which are related but different ideas. Stereotypes indicate expectations and beliefs about an individual or a group, prejudice denotes feelings, and discrimination expresses behaviors. People are likely to be astonished whenever a Black person says that he or she is a physicist. This paper aims to raise awareness of the underrepresentation of Black physics professors and researchers in Brazil and how the lack of quality high school physics education impacts Black and poor students in Brazil. Finally, some considerations on how physics education can assist minority students in overcoming social barriers that contribute to their underrepresentation are presented.

On the other hand, and because of the publication of Obras Completas by Ortega, we find ourselves with a new order of the writings from the philosopher and an appropriate index for research.

Communitopia, a 501(c)3 organization, uses humor, new media, and the short video format to engage and empower audiences and improve climate literacy. Our main project, the Don't Just Sit There - Do Something! video series (http://djst.tv), takes the complex subject of climate science, breaks it down into digestible nuggets of short, funny video, and couples it with easy actions viewers can take to make a difference. The series has 25 episodes so far, and more than 80,000 views on YouTube. We are reaching our target audience of high-school-age and adult viewers in the United States (94% of viewers are known to fit this demographic). Don't Just Sit There - Do Something! uses a strategic model for breaking through the fear and dread around climate change in the general population. It uses humor, positivity and brevity to frame the issue, and gives the audience simple actions designed to empower in each self-contained episode. We approach each piece of the climate puzzle with scientific rigor, and cite all our sources. Our approach is light-hearted and fun, because it is a more productive way to have a conversation about tough issues than scolding and guilt. The series is ongoing, and we are always focused on climate change. To determine the efficacy of our approach and efforts, we measure video views and other metrics through our YouTube channel, compile feedback and comments through YouTube and other social media outlets, and track actions taken through web metrics (click-through rates). We are also currently working with the Behavioral and Community Health Sciences Department at the University of Pittsburgh Graduate School of Public Health to evaluate the videos' impact. From August-October 2015, we are using an online survey to evaluate the Don't Just Sit There - Do Something! series. We will assess viewers' climate change education and awareness, commitment to support action steps that alleviate climate change, and inclination to support policy action before and

Don Giovanni Goes to Prison: Teaching Opera behind Bars

2016-12-01

Full Text Available Teaching opera in prison presents challenges, such as limits imposed on printed and recorded material to study it, or the audio-visual technology in the classroom space, yet, no other experience can be so inspiring and rewarding for everybody involved. This essay focuses on teaching opera, in particular Mozart’s Don Giovanni, to imprisoned students in America. It addresses pedagogical challenges on how to teach opera in prison and advocates for the need to leave the ivory tower of academia and engage in social action. If opera is still perceived as an elitist art form, it is because it is artificially kept that way by being practiced, taught, studied, and promoted only among an exclusive sector of our population.

This work presents an approach for neural network based transient identification which allows either dynamic identification or a 'don't know' response. The approach uses two 'jump' multilayer neural networks (NN) trained with the backpropagation algorithm. The 'jump' network is used because it is useful to dealing with very complex patterns, which is the case of the space of the state variables during some abnormal events. The first one is responsible for the dynamic identification. This NN uses, as input, a short set (in a moving time window) of recent measurements of each variable avoiding the necessity of using starting events. The other one is used to validate the instantaneous identification (from the first net) through the validation of each variable. This net is responsible for allowing the system to provide a 'don't know' response. In order to validate the method, a Nuclear Power Plant (NPP) transient identification problem comprising 15 postulated accidents, simulated for a pressurized water reactor (PWR), was proposed in the validation process it has been considered noisy data in order to evaluate the method robustness. Obtained results reveal the ability of the method in dealing with both dynamic identification of transients and correct 'don't know' response. Another important point studied in this work is that the system has shown to be independent of a trigger signal which indicates the beginning of the transient, thus making it robust in relation to this limitation.

Xiebai is an edible Chinese herb with various health and therapeutic benefits. To evaluate its nutritional and health values, the free amino acids and derivatives of its two botanical origins (i.e., Allium chinense G. Don and Allium macrostemon Bunge) were isolated using a solvent extraction method and analyzed using automatic amino acid analysis and ultra-performance liquid chromatography-quadrupole-time of flight (UPLC-Q-TOF) mass spectrometry. Our data show that both plants contain abundant free amino acids, and the amount of total free amino acids in A. chinense G. Don is higher than that in A. macrostemon Bunge. The free amino acid compositions in the two plants are qualitatively similar, including nineteen proteinogenic and four non-proteinogenic amino acids. The identified proteinogenic amino acids include eight essential amino acids and five semi-essential amino acids. The sum of essential and semi-essential amino acids accounts for 64.9% and 69.7% of the total free amino acids of the two plants, respectively. The principal amino acids of both plants, from highest concentration to lowest concentration, are arginine, glutamine, glutamic acid, asparagine and serine. A. chinense G. Don is also rich in citrulline and lysine. In addition, two amino acid derivatives were identified from the two plants, i.e., the proline analog N‑methyl‑proline and the dipeptide H-Glu-Tyr-OH. For the first time, the presence of N‑methyl‑proline in the plants of the Allium genus and the presence of H-Glu-Tyr-OH in unprocessed food sources are reported. The influences of the identified substances on the flavor, nutrition and health values of Xiebai are discussed. Copyright © 2018 Elsevier Ltd. All rights reserved.

Preventive health services are important for child development, and parents play a key role in facilitating access to services. This study examined how parents' reasons for not having a usual source of care were associated with their children's receipt of preventive services. We used pooled data from the 2011-2014 National Health Interview Survey (n = 34 843 participants). Parents' reasons for not having a usual source of care were framed within the Penchansky and Thomas model of access and measured through 3 dichotomous indicators: financial barriers (affordability), attitudes and beliefs about health care (acceptability), and all other nonfinancial barriers (accessibility, accommodation, and availability). We used multivariable logistic regression models to test associations between parental barriers and children's receipt of past-year well-child care visits and influenza vaccinations, controlling for other child, family, and contextual factors. In 2014, 14.3% (weighted percentage) of children had at least 1 parent without a usual source of care. Children of parents without a usual source of care because they "don't need a doctor and/or haven't had any problems" or they "don't like, trust, or believe in doctors" had 35% lower odds of receiving well-child care (adjusted odds ratio = 0.65; 95% CI, 0.56-0.74) and 23% lower odds of receiving influenza vaccination (adjusted odds ratio = 0.77; 95% CI, 0.69-0.86) than children of parents without those attitudes and beliefs about health care. Financial and other nonfinancial parental barriers were not associated with children's receipt of preventive services. Results were independent of several factors relevant to children's access to preventive health care, including whether the child had a usual source of care. Parents' attitudes and beliefs about having a usual source of care were strongly associated with their children's receipt of recommended preventive health services. Rates of receipt of child preventive

Una de las bibliotecas más importantes del siglo XVII fue la de don Lorenzo Ramírez de Prado, erudito y bibliófilo, que reunió en su casa madrileña por lo menos unos 8.951 volúmenes. Quizás la especial relación que tuvo don Lorenzo con América a lo largo de su vida –fue ahijado del humanista Pedro de Valencia, cronista de Indias; fue Consejero de Indias desde 1626 hasta su muerte, como también lo fue su hermano Alonso; otro de sus hermanos, Marcos, fue obispo de Michoacán, etc.–, influyó en que entre los fondos de su biblioteca se encuentren las principales obras de tema americano y algunas editadas en el Nuevo Mundo. En este trabajo pretendemos, tras el examen exhaustivo del inventario, ofrecer una relación de los registros del fondo americano (tema americano y obras impresas en América que existían en la librería en el momento en que se inventarió, seguido del análisis y las conclusiones de este.

Characteristics of currently the highest sensitivity 3D-only PET scanner (CTI/Siemens 966/EXACT3D) have been studied. The device has 48 rings (82cm diameter) of BGO detector elements (4.0 x 4.1 x 30mm, 8 x 8 block) and an axial FOV of 23.4cm. Attenuation correction is carried out with a point source of 137 Cs which moves under hydraulic pressure in a helical tube. Transaxial resolution is 4.7mm 1cm from the centre of the FOV increasing, in the radial direction to 6.3mm and 7.3mm at 10cm and 15cm. At a lower threshold of 350keV, the scatter fraction is 40%. With scatter subtracted, the efficiency (20cm cylinder) is 6.9 x 104 cps/kBq/ml (maximum ring difference of 40); the absolute sensitivity is 5.8%. In the current configuration, the maximum total coincidence event rate is limited to about 3 x 10 6 per sec. The maximum trues rate is about 850kcps (90MBq in the FOV). List mode acquisition has been implemented to maximize temporal resolution and optimize data storage. The more open geometry of this device gives a broader singles FOV. Hence administered doses and/or additional side-shielding need to be carefully considered to optimize noise-equivalent counts

Full Text Available Low developed companies do not use ERP solutions for resource management, they don't have CRM systems for tracking customers, online presence is low and consequently they are selling low volumes. Their work does not generate enough capital to buy specialized software and the local community is too small to create open-source software for them.When adapting an open-source enterprise solution, from a certain level of integration, it is necessary to align to the Romanian legislation. For this you need more than a simple translation. For example, in accounting, the Romanian chart of accounts should be used, the local fiscal calendar, the rules of the Romanian legislation and the specific identifiers for Romanian companies. The solution: Open source applications can be localized. A small community cannot create complex system starting from nothing, but they can adapt existing ones already created and used all over the world. Given the individual characteristics of the Romanian market, open source ERP, CM and e-commerce will be integrated by specialized consultancy agency in Romania just as is done in France (Compiere, Spain (Openbravo, Belgium (OpenERP or the United States (Apache oFBiz. This will not generate license costs for the companies, only the expenses for hardware and implementation consultancy. If we can create a common infrastructure, hardware cost will be waived for cloud SaaS offering, in opposition with the on-premise option.

Risk Acceptance Personality Paradigm: How We View What We Don't Know We Don't Know

Science.gov (United States)

Massie, Michael J.; Morris, A. Terry

2011-01-01

The purpose of integrated hazard analyses, probabilistic risk assessments, failure modes and effects analyses, fault trees and many other similar tools is to give managers of a program some idea of the risks associated with their program. All risk tools establish a set of undesired events and then try to evaluate the risk to the program by assessing the severity of the undesired event and the likelihood of that event occurring. Some tools provide qualitative results, some provide quantitative results and some do both. However, in the end the program manager and his/her team must decide which risks are acceptable and which are not. Even with a wide array of analysis tools available, risk acceptance is often a controversial and difficult decision making process. And yet, today's space exploration programs are moving toward more risk based design approaches. Thus, risk identification and good risk assessment is becoming even more vital to the engineering development process. This paper explores how known and unknown information influences risk-based decisions by looking at how the various parts of our personalities are affected by what they know and what they don't know. This paper then offers some criteria for consideration when making risk-based decisions.

The origin of atmospheric dissolved organic nitrogen (DON) deposition is not very clear at present. Across China, the DON deposition was substantially larger than that of world and Europe, and we found significant positive correlation between contribution of DON and the deposition flux with pristine site data lying in outlier, possibly reflecting the acute air quality problems in China. For a case study in Northeast China, we revealed the deposited DON was mainly derived from intensive agricultural activities rather than the natural sources by analyzing the compiled dataset across China and correlating DON flux with NH 4 + –N and NO 3 − –N. Crop pollens and combustion of fossil fuels for heating probably contributed to summer and autumn DON flux respectively. Overall, in Northeast China, DON deposition could exert important roles in agro-ecosystem nutrient management and carbon sequestration of natural ecosystems; nationally, it was suggested to found rational network for monitoring DON deposition. -- Highlights: •Contribution and deposition flux of DON across China was positively correlated. •Deposited DON was more influenced by human in China than across the world and Europe. •DON of a farmland in Northeast China was mainly derived from agricultural activities. •Crop pollen and combustion of fossil fuels contributed to summer and autumn DON. •Deposited DON should not be neglected when evaluating its ecological impacts. -- Synthesis of DON deposition across China implied regional importance of anthropogenic sources, and an observation in Northeast China suggested the ecological significances of the DON flux should be considered

Anthropogenic activities are altering carbon and nitrogen concentrations in surface waters globally. The stoichiometry of carbon and nitrogen regulates important watershed biogeochemical cycles; however, controls on carbon and nitrogen ratios in aquatic environments are poorly understood. Here we use a multi-biome and global dataset (tropics to Arctic) of stream water chemistry to assess relationships between dissolved organic carbon (DOC) and nitrate, ammonium and dissolved organic nitrogen (DON), providing a new conceptual framework to consider interactions between DOC and the multiple forms of dissolved nitrogen. We found that across streams the total dissolved nitrogen (TDN) pool is comprised of very little ammonium and as DOC concentrations increase the TDN pool shifts from nitrate to DON dominated. This suggests that in high DOC systems, DON serves as the primary source of nitrogen. At the global scale, DOC and DON are positively correlated (r2 = 0.67) and the average C: N ratio of dissolved organic matter (molar ratio of DOC: DON) across our data set is approximately 31. At the biome and smaller regional scale the relationship between DOC and DON is highly variable (r2 = 0.07 - 0.56) with the strongest relationships found in streams draining the mixed temperate forests of the northeastern United States. DOC: DON relationships also display spatial and temporal variability including latitudinal and seasonal trends, and interactions with land-use. DOC: DON ratios correlated positively with gradients of energy versus nutrient limitation pointing to the ecological role (energy source versus nutrient source) that DON plays with stream ecosystems. Contrary to previous findings we found consistently weak relationships between DON and nitrate which may reflect DON's duality as an energy or nutrient source. Collectively these analyses demonstrate how gradients of DOC drive compositional changes in the TDN pool and reveal a high degree of variability in the C: N ratio

The increasing popularity of immortelle (Helichrysum italicum (Roth) G. Don) and its products, particularly in the cosmetic industry, is evident nowadays. This plant is a source of coumarins, especially scopoletin, which are highly soluble in supercritical CO2 . The objective of this study was to perform the supercritical CO2 extraction process of Helichrysum italicum flowers at different values of pressure and temperature and to optimise the extraction process using response surface methodology in terms of obtaining the highest extraction yield and yield of extracted scopoletin. Extraction was performed in a supercritical extraction system under different extraction conditions of pressure and temperature determined by central composite rotatable design. The mass of flowers in the extractor of 40 g, extraction time of 90 min and CO2 mass flow rate of 1.94 kg/h were kept constant during experiments. Antioxidant activity was determined using the DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging assay method. Scopoletin concentration was determined by HPLC. Changes in extraction conditions affect the extracting results remarkably. The greatest extraction yield (6.31%) and the highest yield of scopoletin (1.933 mg/100 g) were obtained under extraction conditions of 20 MPa and 40°C. Extracts have also proven to possess antioxidant activity (44.0-58.1% DPPH scavenging activity) influenced by both temperature and pressure applied within the investigated parameters. The extraction conditions, especially pressure, exhibited significant influence on the extraction yield as well as the yield of extracted scopoletin and antioxidant activity of extracts.

In the last years, many different approaches based on neural network (NN) has been proposed for transient identification in nuclear power plants (NPP). Some of them focus the dynamic identification using recurrent neural networks however, they are not able to deal with unrecognized transients. Other kind of solution uses competitive learning in order to allow the 'don't know' response. In this case dynamic, dynamic features are not well represented. This work presents a new approach for neural network based transient identification which allows either dynamic identification and 'don't know'response. Such approach uses two multilayer neural networks trained with backpropagation algorithm. The first one is responsible for the dynamic identification. This NN uses, a short set (in a movable time window) of recent measurements of each variable avoiding the necessity of using starting events. The other one is used to validate the instantaneous identification (from the first net) through the validation of each variable. This net is responsible for allowing the system to provide 'don't know' response. In order to validate the method a NPP transient identification problem comprising 15 postulated accidents, simulated for a pressurized water reactor, was proposed in the validation process it has been considered noising data in other to evaluate the method robustness. Obtained results reveal the ability of the method in dealing with both dynamic identification of transients and correct 'don't know' response.

Bacterial epimerization as a route for deoxynivalenol detoxification: the influence of growth and environmental conditions.

Directory of Open Access Journals (Sweden)

Jian Wei eHe

2016-04-01

Full Text Available Deoxynivalenol (DON is a toxic secondary metabolite produced by several Fusarium species that infest wheat and corn. Food and feed contaminated with DON pose a health risk to both humans and livestock and form a major barrier for international trade. Microbial detoxification represents an alternative approach to the physical and chemical detoxification methods of DON-contaminated grains. The present study details the characterization of a novel bacterium, Devosia mutans 17-2-E-8, that is capable of transforming DON to a non-toxic stereoisomer, 3-epi-deoxynivalenol under aerobic conditions, mild temperature (25-30 oC, and neutral pH. The biotransformation takes place in the presence of rich sources of organic nitrogen and carbon without the need of DON to be the sole carbon source. The process is enzymatic in nature and endures a high detoxification capacity (3 µg DON/h/108 cells. The above conditions collectively suggest the possibility of utilizing the isolated bacterium as a feed treatment to address DON contamination under empirical field conditions.

Denver's Pioneer Astronomer: Herbert Alonso Howe (1858-1926)

Science.gov (United States)

Howe, H. J.; Stencel, R. E.; Fisher, S.

1999-05-01

Herbert A. Howe arrived at Denver University (DU) to teach autumn 1880 classes, in math, astronomy and surveying. Howe established himself with clever solutions to the Kepler problem for orbit determinations in thesis work at Cincinnati Observatory. Riding the economic expansion of Colorado gold and silver mining in 1888, the University accepted a proposed gift of a major observatory, offered by Denver real estate baron, Humphrey Chamberlin. The result features a 20 inch aperture Alvan Clark refractor, which still ranks among the largest telescopes of the era. With the observatory building ready, the Silver Panic of 1893 -- when the US Congress dropped silver reserves from the currency basis -- burst the Denver economic bubble. Chamberlin was unable to complete payments on the balances due. Clark and G.N.Saegmuller (Fauth and Co.) at personal expense, delivered on the optics and telescope assemblies in 1894, but would wait for repayment. Sadly, this fiscal crisis affected DU for over a decade. Professor Howe, while observatory director, found himself consumed as Dean and Acting Chancellor for a young, struggling university, at the expense of the astronomy future that had looked so bright in 1892. Absent the Silver Panic, Howe would have probably been given an endowed chair in astronomy, as promised by Chamberlin. The complexion of American astronomy at the time of the birth of the American Astronomical Society in 1899 might have been different, in terms of US observing sites, etc. We are fortunate to have extensive Prof.Howe's daily diaries now in the University archives. These describe Howe's view of progress on the observatory, meetings with astronomy notables, plus vignettes of the life and times of Denver and the nation. Grandson, Herbert Julian Howe rediscovered their existence and is summarizing them in the form of a biography entitled: The Pioneer Astronomer. DU archival records contain numerous original letters from late 19th century astronomy luminaries

Tsunami survivors' perspectives on vulnerability and vulnerability reduction: evidence from Koh Phi Phi Don and Khao Lak, Thailand.

Steckley, Marylynn; Doberstein, Brent

2011-07-01

This paper presents the results of primary research with 40 survivors of the 2004 Indian Ocean tsunami in two communities: Khao Lak (n=20) and Koh Phi Phi Don (n=20), Thailand. It traces tsunami survivors' perceptions of vulnerability, determines whether residents felt that the tsunami affected different communities differently, identifies the populations and sub-community groups that survivors distinguished as being more vulnerable than others, highlights community-generated ideas about vulnerability reduction, and pinpoints a range of additional vulnerability reduction actions. Tsunami survivors most consistently identified the 'most vulnerable' community sub-populations as women, children, the elderly, foreigners, and the poor. In Khao Lak, however, respondents added 'Burmese migrants' to this list, whereas in Koh Phi Phi Don, they added 'Thai Muslims'. Results suggest that the two case study communities, both small, coastal, tourism-dominated communities no more than 100 kilometres apart, have differing vulnerable sub-groups and environmental vulnerabilities, requiring different post-disaster vulnerability reduction efforts. © 2011 The Author(s).

Authority as paradox: the transformations of Don Quijote.

Science.gov (United States)

Priel, Beatriz

2006-12-01

The author's contention is that the analysand's temporary attribution of authority to the analyst is inherent in the analytic situation; this is seen as a transitional and paradoxical form of authority pertaining neither to internal nor external reality, but dwelling in the analytic third. The author proposes a conceptualization of psychoanalytic authority as a form of aesthetic authority according to Gadamer's definitions. While the scientific and hermeneutic codes for the understanding of authority in psychoanalysis assume that the main issue at stake is the delimitation of the objectivity or the subjectivity of the analyst's knowledge, this aesthetic perspective centres on the analysand's attribution of a claim of truth to analytic interpretations, and on the experience of recognition. The experience of recognition of a possible truth is particular and context-bound, as well as self-transformational. A reading of three episodes from Cervantes's The history of Don Quixote de la Mancha illuminates the transitional and paradoxical character of aesthetic authority within a transformational dialogue. These episodes are read as dramatizations of different positions vis-à-vis the paradoxical authority that characterizes transformational dialogues.

Mothers 'don't like it; never tried it': Blind Sensory Test of a Homemade Chicken Liver Baby Food, a Source of Iron, by Infants and their Mothers.

Campos, Viviani Jaques; Morais, Tania Beninga

2015-08-01

A homemade chicken liver baby food (CLBF) that meets infants' nutritional requirements was developed and its acceptance by children and their mothers determined. CLBF's nutritional content was determined by chemical analyses. A blind sensory test (ST) by 50 infants 7-12 months old and their mothers of CLBF and ground beef baby food (GBBF) was applied. Mothers' preferences for liver and beef, answers of an hedonic scale and infants' acceptance were investigated. CLBF met the nutritional requirements for infants. There were no significant differences in the ST between the CLBF and GBBF, either for infants or for their mothers. There was no correlation between mothers' like or dislike of liver and the ST scores. Infants tried and liked the CLBF that match dietary recommendations and could help prevent iron deficiency. Mothers, on the other hand, demonstrated an 'I don't like it; I never tried it' attitude. © The Author [2015]. Published by Oxford University Press. All rights reserved.

Stable Isotopic Composition of Dissolved Organic Nitrogen Fueling Brown Tide in a Semi-Arid Texas Estuary

Science.gov (United States)

Campbell, J.; Felix, J. D. D.; Wetz, M.; Cira, E.

2017-12-01

Harmful algal blooms (HABs) have the potential to adversely affect the water quality of estuaries and, consequently, their ability to support healthy and diverse ecosystems. Since the early 1990s, Baffin Bay, a semi-arid south Texas estuary, has progressively experienced harmful algal blooms. The primary species of HAB native to the Baffin Bay region, Aureoumbra lagunensis, is unable to utilize nitrate as a nutrient source, but instead relies on forms of reduced nitrogen (such as dissolved organic nitrogen (DON) and ammonium (NH4+)) for survival. DON levels in Baffin Bay (77 ± 10 µM) exceed the DON concentrations of not only typical Texas estuaries, but estuaries worldwide. Additionally, DON accounts for 90% of the total dissolved nitrogen (TDN) in Baffin Bay, followed by NH4+ at 8%, and NO3-+NO2- contributing 2%. Due to the dependence of A. lagunensis on the reduced forms of nitrogen as an energy source and the elevated concentrations of DON throughout the bay, it is important to identify the origin of this nitrogen as well as how it's being processed as it cycles through the ecosystem. The presented work investigates the stable isotopic composition of reactive nitrogen (Nr) (δ15N-DON, δ15N-NH4+, and δ15N-NO3-) in Baffin Bay samples collected monthly at nine stations over the period of one year. The work provides preliminary evidence of Nr sources and mechanisms driving favorable conditions for HAB proliferation. This information can be useful and applicable to estuarine ecosystems in various settings, advancing scientific progress towards mitigating blooms. Additionally, since the elevated concentrations of DON make Baffin Bay uniquely suited to investigate its sources and processing, this project will aid in characterizing the role of this largely unstudied form of Nr, which could provide insight and change perceptions about the role of DON in nitrogen dynamics.

Astronomy in Denver: Centenary of the 1918 total solar eclipse across Denver

Science.gov (United States)

Stencel, Robert E.

2018-06-01

Totality during the 2017 August 21 solar eclipse (Saros 145) traveled along a path across the United States similar to that which occurred for the eclipse on 1918 June 8 (Saros 126), but with a less west-northerly track. This placed Denver and its then new Chamberlin Observatory in the path of totality. Denver University astronomy Professor Herbert Howe offered use of the Chamberlin Observatory 20-inch f/15 refractor, with its Clark doublet lens and Saegmueller mounting, in service of eclipse-related research. In preparation for the eclipse, Professor Howe and assistants had spent the last three months of 1917, refurbishing mechanical aspects of the telescope. Edwin Frost, then Director of Yerkes Observatory expressed interest and made a reconnaissance visit to the area in September 1917, reporting results in the Feb. 1918 issue of Popular Astronomy ( http://adsabs.harvard.edu/abs/1918PA.....26R.103F ). Frank Schlesinger, then director of Allegheny Observatory, asked if he might attach a special camera for star photography to the telescope at the eclipse, to test displacement of stars, in order to test a prediction of relativity theory. Among the additional visiting astronomical luminaries present on that June day in 1918 were Annie J. Cannon (Harvard), John Duncan (Wellesley), Herbert R. Morgan (U.S. Naval Observatory) and Robert Trumpler (Berkeley).

2016-11-01

Full Text Available Don Quixote is the most recognized work of Spanish and universal literature, and teaching adaptations in schools are very important for children to understand their reading. Compulsory reading of the work during the period between the Second Republic and the Franco regime caused many school adaptations to suit their classroom teaching. This study focused on the graphic elements of the work from a communicative and iconographic perspective, allows through content analysis of a cataloged and representative sample of the covers of school adaptations, verify that the hard political interventionism that suffered the work according antagonistic dominant ideologies did not influence their design, because these spaces were not ideologically charged, despite being the first element of commercial persuasion of the book and its role motivate reading. Analytical data along with historical explain the existence of a commercial image of Quixote free of ideological connotations (on the cover, from his iconographic path, which we have not found significant differences from the two dominant ideologies. However, the politicization of the work contributed to Don Quixote became the national hero of children and adults and a universal benchmark of behavior full of great ethical and moral values.

When Marcel Mauss's Essai sur le Don becomes The Gift: variations on the theme of solidarity.

Science.gov (United States)

Bateman, Simone

2016-12-01

Since the early 1970s, Marcel Mauss's Essai sur le Don (1923), translated into English as The Gift in 1954, has been a standard reference in the social science and bioethical literature on the use of human body parts and substances for medical and research purposes. At that time, three social scientists-political scientist Richard Titmuss in the United Kingdom and sociologist Renée C. Fox working with historian Judith Swazey in the United States-had the idea of using this concept to highlight the fundamental structure of the biomedical practices they were studying, respectively, blood donation, and hemodialysis and organ transplantation. The fact that these first applications of Mauss's essay should emerge in English- rather than in French-speaking countries raises the question of what the translation of the essay, and notably of the word don as gift, may have to do with this fact. Reading Mauss in translation undoubtedly inspired a seminal approach to interpreting medical and research practices based on bodily giving. This article posits that something may have also been lost: a much broader concept of giving with unquestionable links to the Durkheimian concept of solidarity, which Mauss conceptualizes not only as an obligation but also as a liberty to give.

Dealing with Don Juan’s Legacy: Rebellion and Inheritance in Lídia Jorge’s O vale da paixão

Directory of Open Access Journals (Sweden)

Sebastian Patron Saade

2016-04-01

Full Text Available This article analyzes how Lídia Jorge’s nameless woman narrator in O vale da paixão reconstructs through a story of resistance the legacy of her donjuanesque father/uncle. Dealing with the father’s legacy becomes a priority for a narrator who wishes both to affirm her feminine identity and appropriate her father’s memory. However, remembrance is not devoid of perils. To rescue her father’s life from slander, the narrator must find ways to reinterpret the myth of the rebellious, globetrotter womanizer he impersonates in the traditional patriarchal unit. Using Jacques Lacan writings on drives and Alenka Zupančič’s reading of Don Juan, I will show how Lídia Jorge’s narrative rewriting of the myth of Don Juan disrupts the patriarchal system of values from which it draws its strength.This article is published under a CC-BY license https://creativecommons.org/licenses/by/3.0/

On the Paleopathological Features of the Sarmatian Population of the Lower Volga and the Lower Don Regions in the 4th - 1st Centuries B.C.

Directory of Open Access Journals (Sweden)

Pererva Evgeniy Vladimirovich

2015-12-01

Full Text Available The paper is dedicated to the study of paleopathological features of the early Sarmatians. The bone remains which are the material to this research originate from tombs beneath burials mounds from the area of the Lower Volga and the Lower Don regions. The author applied the technique of analysis of bone remains that was introduce into scientific use by A.P. Buzhilova. As a result of the conducted research, the author found out that the early Sarmatians are most likely to have come from the Lower Volga and the Don regions being migrating population which was not uniform in its composition. Some of the Sarmatians, men, in the first place, were overweight and suffered from obesity. The early Sarmatian population in the Lower Volga region and the Don region experienced the periods of prolonged starvation that resulted in chronic diseases which were exacerbated during winters or in dry years. At the same time, the Sarmatians rarely suffered from specific infectious diseases due to the low density of population. War was an integral part of the Sarmatian that was often reflected on skull bones and post-cranial skeleton as war wounds and traumas due to ritual ceremonies.

Adult and child use of love, like, don't like and hate during family mealtimes. Subjective category assessments as food preference talk.

Science.gov (United States)

Wiggins, Sally

2014-09-01

Food preference is now a ubiquitous concept in eating research, and closely associated with actual consumption, particularly in relation to children's food preferences. Research in this area is beginning to reveal the effects of parent-child interaction on eating practices though relatively little attention has been paid to the discursive and lexical processes involved. Food preferences are typically associated with the terms 'likes' and 'dislikes' in food preference research. By contrast, adults and children typically use the terms 'love', 'like', 'don't like' and 'hate' to construct and manage food preferences in everyday meal conversations. A corpus of 270 video- and audio-recorded English and Scottish family mealtimes, involving children aged 1-17 years, was searched and analysed for any and all occurrences of subjective category assessments (SCAs; e.g., 'I like X'), featuring the terms 'love', 'like', 'don't like' and 'hate'. Discursive psychology was used to analyse the transcripts and recordings, and illustrated the disparity between adult and child use of SCAs and food preference talk. Within the data set, parents typically made claims about what their children like, and in doing so claimed epistemic primacy over their children's food preferences. Children, by contrast, typically made claims about their own 'don't likes' and likes, and these were frequently countered by their parents or treated as inappropriate claims. Implications for how parents and researchers might reorient to the food preferences lexicon are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

The geochemistry of Don Juan Pond: Evidence for a deep groundwater flow system in Wright Valley, Antarctica

Science.gov (United States)

Toner, J. D.; Catling, D. C.; Sletten, R. S.

2017-09-01

Don Juan Pond (DJP), Antarctica, is one of the most unusual surface waters on Earth because of its CaCl2-rich composition. To investigate the evolution of pond waters during closed-basin evaporation and to understand the source of brines responsible for the chemistry of DJP, we apply a newly developed low-temperature aqueous model in the Na-K-Ca-Mg-Cl system to DJP. By modeling the closed-basin evaporation of DJP and comparing ionic ratios between DJP surface water, deep groundwater, shallow groundwater, and other surface chemistries in Wright Valley, we find that DJP is best explained by upwelling deep groundwater, as opposed to recent hypotheses proposing shallow groundwater sources. The early closed-basin evolution of brines in our model accurately predicts observed chemistries in DJP; however, late-stage closed-basin evaporation produces Mg-K-rich brines and salts that do not match the CaCl2-rich brine in DJP. Based on groundwater inflow rates to DJP, we estimate that even the most concentrated brines in DJP have undergone closed-basin evaporation for less than a year. To explain the observed lack of Mg2+ and K+ accumulation in DJP over time, and the surprisingly young age for the brines, we deduce that DJP is a localized upwelling from a regional groundwater flow-through system in which evaporated DJP brines are recycled back into the subsurface over yearly timescales. The existence of a regional groundwater flow system beneath DJP has implications for water and solute budgets in cold desert ecosystems, and may provide clues for the formation of groundwater and aqueous flows on Mars.

Size, Albedo, and Taxonomy of the Don Quijote Space Mission Target

2006-03-01

Rendezvous and lander missions are a very effective but very expensive way of investigating Solar-System bodies. The planning, optimization and success of space missions depends crucially on prior remotely-sensed knowledge of target bodies. Near-Earth asteroids (NEAs), which are mainly fragments of main-belt asteroids, are seen as important goals for investigation by space missions, mainly due to the role their forebears played in planet formation and the evolution of the Solar System, but also for the pragmatic reason that these objects can collide with the Earth with potentially devastating consequences. The European Space Agency is currently planning the Don Quijote mission to a NEA, which includes a rendezvous (and perhaps a lander) spacecraft and an impactor vehicle. The aim is to study the physical properties of the target asteroid and the effects of the impact on its dynamical state, as a first step in considering realistic mitigation measures against an eventual hazardous NEA. Two potential targets have been selected for the mission, the preferred one being (10302) 1989 ML, which is energetically easier to reach and is possibly a scientifically interesting primitive asteroid. However, due to the ambiguity of available spectral data, it is currently not possible to confidently determine the taxonomic type and mineralogy of this object. Crucially, the albedo is uncertain by a factor of 10, which leads to large uncertainties in the size and mass and hence the planned near-surface operations of Don Quijote. Thermal-infrared observations are urgently required for accurate size and albedo determination. These observations, which can only be carried out by Spitzer and would require only a modest amount of observing time, would enable an accurate diameter to be derived for the first time and the resulting albedo would remove the taxonomic ambiguity. The proposed Spitzer observations are critical for effective mission planning and would greatly increase our

This book gathers seven founder articles (including 4 original translations), harbingers of the present day climate change. Written during the 19. century by famous scientists like Joseph Fourier, Claude Pouillet, James Croll, John Tyndall, Svante Arrhenius and Thomas Chamberlin, they relate a century of major progress in the domain of Earth's sciences in praise of these scientists. This book allows to (re)discover these texts: discovery of the greenhouse effect principle (Fourier), determination of solar radiation absorption by the atmosphere (Pouillet), rivalry between the astronomical theory of glacial cycles (Croll) and the carbon dioxide climatic theory (Tyndall), influence of the CO 2 concentration in the atmosphere on the global warming (Arrhenius), and confirmation of the major role of CO 2 in the Earth's temperature regulation (Chamberlin).

Full Text Available Daily use of insult, slander, in the societies of the Early Modern Age, is also present in the voices of the protagonists of Don Quixote. However, the Ingenious Gentleman and his squire, do not use the insult in the same way. This will depend on the social position of insulted and offender (noble or villain, and the circumstances surrounding it. However, social reality, collected in different court cases, shows that the insult did not respect, in the same way as in the novel, the stratified social structure.

Rheum australe D. Don (Polygonaceae) has been commonly used in traditional medicine for a wide range of ailments related to the circulatory, digestive, endocrine, respiratory and skeletal systems as well as to infectious diseases. To provide the up-to-date information that is available on the botany, traditional uses, phytochemistry, pharmacology and toxicology of Rheum australe. Additionally, to highlight the possible uses of this species to treat different diseases and to provide a basis for future research. The present review covers the literature available from 1980 to 2011. The information was collected from scientific journals, books, theses and reports via a library and electronic search (Google Scholar, Web of Science and ScienceDirect). Ethnomedical uses of Rheum australe have been recorded from China, India, Nepal and Pakistan for 57 different types of ailments. The phytochemical studies have shown the presence of many secondary metabolites belonging to anthraquinones, stilbenes, anthrones, oxantrone ethers and esters, chromones, flavonoids, carbohydrate, lignans, phenols and sterols. Crude extracts and isolated compounds from Rheum australe show a wide spectrum of pharmacological activities, such as antidiabetic, anti-inflammatory, antifungal, antimicrobial, antioxidant, anticancer, hepatoprotective and immune-enhancing activities, as well as a usefulness for improving renal function. Rheum australe has been widely used source of medicine for years without any adverse effects. Many studies have provided evidence for various traditional uses. However, there is a need for additional studies of the isolated compounds to validate the traditional uses in human models. The present review on the botany, traditional uses, phytochemistry and toxicity has provided preliminary information for further studies and commercial exploitations of the plant.

Full Text Available Shoot buds isolated from in vitro shoot cultures of Catalpa ovata G. Don were encapsulated using 3% sodium alginate with sucrose (3% and 50 mM calcium chloride. The morphogenic response of encapsulated buds was affected by such factors, like composition of the media and the presence of growth regulators. The highest frequency of plantlet germination from encapsulated buds (70% within 4 weeks was obtained on Woody Plant medium (WP (Lloyd and McCown 1980 containing indole-3-butyric acid (IBA (1 mg/l. The process was substantially inhibited by cold-storage (4oC of encapsulated buds. In this case, the frequency response ranged from 3% to 22% dependent on storage period (28 or 42 days and the presence of the paraffin coat covering the alginate capsules. The plantlets developed from both unstored and stored encapsulated buds of C. ovata were transplanted to soil and grew in pots to phenotypically normal plants.

Qi, Wang; Fang Yee, Lim; Jiangyong, Hu

2014-12-01

The presence of organic compounds in water sources is one of the concerns in water treatment. They are potential precursors of disinfection byproducts (DBPs) and thus induce health problems in humans. Among the emerging DBPs, carcinogenic compound N-nitrosodimethylamine (NDMA) has been receiving attention during the last decade. This study examined the characteristics of organic components in various water sources and investigated their relationships with NDMA formation. Experiments were carried out on selected water samples from both natural water and wastewater. Results showed similar NDMA formation kinetics for both water sources. However, more contribution of NDMA precursors was found to be from the wastewater due to its higher organic nitrogen content. NDMA formation potential (NDMAFP) of secondary effluent ranged from 264 to 530 ng/L. A correlation study between organic compound characteristics and NDMAFP indicated that the majority of NDMA precursors came from dissolved organic nitrogen (DON) compound with small molecular weight (smaller than 500 Da), with correlation R(2) = 0.898. Although secondary treatment removed more than 90% of NDMA precursors, the remaining precursors in secondary effluent would still pose a challenge for water quality.

War as Haiku: The Politics of Don DeLillo’s Late Style

Directory of Open Access Journals (Sweden)

Matthew Shipe

2016-05-01

Full Text Available In the wake of 'Underworld' (1997, Don DeLillo’s work has been cast largely in a minor key. In this essay, I will focus on 'Point Omega', the work that I believe most clearly illuminates the political implications of DeLillo’s late style as it tackles the consequences of the wars in Afghanistan and Iraq. More broadly, I hope to connect 'Point Omega' to the work of DeLillo’s contemporaries that have also speculated on the historical and political implications of the War on Terror. Centering on 'Point Omega', I am interested in how DeLillo has adopted a distinctive narrative form in his most recent fiction that frequently unsettles and complicates the historical narratives that he had established in his earlier work.

Atmospheric organic nitrogen deposition: analysis of nationwide data and a case study in Northeast China.

The origin of atmospheric dissolved organic nitrogen (DON) deposition is not very clear at present. Across China, the DON deposition was substantially larger than that of world and Europe, and we found significant positive correlation between contribution of DON and the deposition flux with pristine site data lying in outlier, possibly reflecting the acute air quality problems in China. For a case study in Northeast China, we revealed the deposited DON was mainly derived from intensive agricultural activities rather than the natural sources by analyzing the compiled dataset across China and correlating DON flux with NH4(+)-N and NO3(-)-N. Crop pollens and combustion of fossil fuels for heating probably contributed to summer and autumn DON flux respectively. Overall, in Northeast China, DON deposition could exert important roles in agro-ecosystem nutrient management and carbon sequestration of natural ecosystems; nationally, it was suggested to found rational network for monitoring DON deposition.

Evaluation of the clinical maxim: "If it ain't broke, don't fix it".

A significant number of patients return to optometric practice dissatisfied with their spectacles. An important question is whether any of these cases are preventable. There are several different clinical maxims that are used to modify the subjective refraction when determining the refractive prescription. These maxims aim to improve patient comfort and adaptation and thereby reduce patient dissatisfaction with new spectacles. They are not based on research evidence, but rather on expert opinion gained from clinical experience. The aim of this study was to retrospectively analyze a large number of case records of dissatisfied patients to assess the possible usefulness of the prescribing maxim "if it ain't broke, don't fix it." Three hundred eighteen non-tolerance cases from a university-based Canadian optometric clinic were categorized by a focus group of optometrists. Three prescribing categories were defined and comprised cases in which application of the proposed maxim may have prevented the recheck eye examination; a more limited application of the maxim for one working distance may have been appropriate; and finally scenarios in which the maxim did not work in that the practitioner was judged to have initially followed the maxim, yet patient dissatisfaction was still reported. The remaining unallocated records comprised prescribing situations outside the scope of this study. Approximately 32% of non-tolerance cases were judged to have been preventable by use of the proposed maxim. Furthermore, an additional 10% reduction in recheck cases may have been possible by a more liberal interpretation of the maxim. Conversely, 4% of cases were deemed to comprise scenarios in which the maxim was followed yet the patient returned later to report problems with their spectacles. The prescribing maxim "if it ain't broke, don't fix it" appears to have a role in reducing recheck eye examinations and improving patient satisfaction with new spectacles.

Full Text Available Resumen: Estudia el presente artículo el fenómeno del quijotismo, ingrediente de la razón, y, por tanto, del comportamiento humano. Pero distingue entre el error del quijotismo estático y el sano proceder del dinámico. Para ello se vale del concepto de razón vital de Ortega y Gasset, así como del Quijote. Con respecto al primero, amplía la utilización que de la magna obra podía haber hecho y no hizo el ilustre filósofo. Y sobre el segundo, destaca sus insuficiencias de contenido, por no haber alcanzado el quijotismo dinámico, es decir, porque, queriendo criticar el idealismo desmedido del caballero manchego, termina por proponer otro quijote. De cualquier forma, el artículo señala cómo el irónico fenómeno del quijotismo no es un juego, para lo cual discute ciertas interpretaciones recientes del Quijote.Abstract: This article studies Quixotism phenomenon, ingredient of vital reason, and, consequently, of human behaviour. However, it distinguishes between the mistake of static quixotism and the right conduct of the dynamic one. In order to do so, it makes use of Ortega y Gasset's concept of Vital Reason, and Don Quixote’s as well. Concerning the first one, it highlights the insufficiency of its content since it has not fulfilled the dynamic quixotism, that is to say, because, with the intention to criticize La Mancha’s Knight’s excessive idealism, it ends up proposing other quixotic person. Anyway, this article points out how the ironic quixotism phenomenon is not a game, for which reason it discusses certain Don Quixote’s recent interpretations.

Tornado type closed magnetic trap for an ECR source

CERN Document Server

Abramova, K B; Voronin, A V; Zorin, V G

1999-01-01

We propose to use a Tornado type closed magnetic trap for creation of a source of mul-ticharged ions with plasma heating by microwave radiation. Plasma loss in closed traps is deter-mined by diffusion across the magnetic field, which increases substantially plasma confinement time as compared to the classical mirror trap [1]. We propose to extract ions with the aid of additional coils which partially destroy the closed structure of the magnetic lines in the trap, but don not influence the total confinement time. This allows for producing a controlled plasma flux that depends on the magnetic field of the additional coil. The Tornado trap also possesses merits such as an opportunity to produce high magnetic fields up to 3 T, which makes possible heating and confinement of plasma with a high density of electrons; plasma stability to magneto-hydrodynamic perturbations because the magnetic field structure corresponds to the "min B" configuration; and relatively low costs. All estimates and calculations were carrie...

A good example is the case of the precentor Don Ventura Ferrer, who led one of the cathedral sections and who, supported by the Vallterra family, sought the control of the first church of the kingdom. On the opposite side was the group of canons represented by the admiral of Aragón, head of the opposing supporters and liable for the precentor’s murder in 1661. This event revealed the overlapping of the ecclesiastic world and the phenomenon of banditry.El clero de la Seo no fue ajeno a las bandositats que aglutinaron a buena parte de la sociedad valenciana durante el siglo XVII.

Cine, literatura y mito: Don Quijote en el cine, más allá de la adaptación

Pardo García, Pedro Javier

2011-04-01

Full Text Available This paper discusses Don Quixote’s presence in film, but in terms of the myth rather than the book, an approach which goes beyond adaptation and opens up the field of study in a significant way. In so doing it proposes a tentative but coherent description of the quixotic myth or narrative pattern as that of the inadequate and romantic imitator/reader of fiction, which is the point of departure for the elaboration of an initial corpus of quixotic movies. The protagonists of these films are frustrated imitators of cinematographic models, female Quixotes who romanticize reality and heroes who are Quixotic because they are not fit for the heroic task they have undertaken. In order to illustrate this deep penetration of the myth into the cinematic medium, a recent example in Spanish cinema will be examined, The Heart of the Warrior (El corazón del guerrero, 2000, a film directed by Daniel Monzón, where these several varieties are at work in a combined and crystal clear way. Our survey will allow us to make a series of distinctions which organise and structure the different kinds of relationship between Don Quixote and film (Cervantean, quixotic and quixotish film and, finally, to draw a series of theoretical conclusions which can be applied to the comparative study of film and literature.

Este trabajo se ocupa de la presencia en el cine de Don Quijote, pero no del libro sino del mito, una perspectiva que va mucho más allá de la adaptación y abre considerablemente el campo de estudio. Para ello, se propone una descripción que se sabe provisional pero intenta ser rigurosa del mito o el patrón narrativo quijotesco como el del lector/imitador romántico e inadecuado de ficción, a partir de la cual se puede elaborar un primer corpus de películas quijotescas. En él se incluyen las protagonizadas por imitadores fallidos de modelos cinematográficos, por Quijotes femeninos que romantizan la realidad y por diversos tipos de héroes que son

Full Text Available This article intends to call attention to the close relationship which exists between the figure of Don Quixote and the marginal characters and assorted weirdoes who appear in German literature during the 18th and 19th centuries. The analysis of the concept of madness in several texts from the late Middle Ages and the Baroque will enable us, on the one hand, to see how the publication of Cervantes’ novel and the consequent changes in society transformed this concept; and, on the other hand, to determine the importance of the idea of insanity for German letters, stressing the decisive role played by Don Quixote therein.

[Spanish neuroscience in times of Don Quixote].

2016-02-16

Miguel de Cervantes Saavedra published his immortal work Don Quixote of La Mancha in a time of crisis and decadence in Spain that occurred during the transition between the 16th and 17th centuries. In 2016 we commemorate the fourth centenary of the death of our distinguished man of letters, and thus in this article we analyse the status of Hispanic neuroscience, both in the Quixote itself and in other works by the most significant contemporary writers of that time. Despite the adverse historical circumstances, the shift from the Renaissance to the Baroque periods, in the Crown of Castile, was a flourishing period for literature (Spanish Golden Age) and other Hispanic arts (painting, sculpture, architecture and music), as well as bearing witness to a prodigious creativity in the field of neuroscience, including the field of natural philosophy. In his book Antoniana Margarita the physician Gomez Pereira laid the foundations for brain mechanism and the concept of conditioned reflexes several decades ahead of his time. The apothecary Miguel Sabuco also anticipated the concept of neurotransmission centuries ahead of his time in his New Philosophy. The physician Juan Huarte de San Juan was the founder of neuropsychology and experimental psychology, and his Examination of Men's Wits has been one of the most influential and widely translated scientific texts of all times. Its concepts are clearly reflected in Cervantes' Quixote. This analysis of Cervantes' work within the cultural setting of the book is intended as a homage to the immortal figure of our 'Prince of Wits' in the fourth centenary of his death.

[Foods related to the novel 'don quixote de la mancha'. did they follow the healthy nutritional recommendations which are advised nowadays?].

2015-01-01

It is known that Miguel de Cervantes's novel 'Don Quixote de La Mancha' has done and is still doing a great contribution to the universal literature. A book that has reached such category and grows in number of its readers, shows multiple dimensions for its study. One of them is nutrition. One of the aims of this study has been to value and expound, according to their own nutrients, the kinds of food cited in 'The Quixote' and in the times of Cervantes. This has allowed the comparison made between ways of nutrition in La Mancha and in Catalonia, as well as the regions situated at the beginning and end of the itinerary covered by its main characters Don Quixote and Sancho Panza. The evaluation of the nutrients in the middle part of the itinerary, placed mainly in Aragón, has not been considered in this study. Another purpose has been to check if these nutrients followed the current recommendations of the Spanish Society of Arteriosclerosis and other valid agreements at the moment.

Sherlock Holmes' or Don Quixote`s certainty? Interpretations of cropmarks on satellite imageries in archaeological investigation

Wilgocka, Aleksandra; RÄ czkowski, Włodzimierz; Kostyrko, Mikołaj; Ruciński, Dominik

2016-08-01

Years of experience in air-photo interpretations provide us to conclusion that we know what we are looking at, we know why we can see cropmarks, we even can estimate, when are the best opportunities to observe them. But even today cropmarks may be a subject of misinterpretation or wishful thinking. The same problems appear when working with aerial photographs, satellite imageries, ALS, geophysics, etc. In the paper we present several case studies based on data acquired for and within ArchEO - archaeological applications of Earth Observation techniques project to discuss complexity and consequences of archaeological interpretations. While testing usefulness of satellite imagery in Poland on various types of sites, cropmarks were the most frequent indicators of past landscapes as well as archaeological and natural features. Hence, new archaeological sites have been discovered mainly thanks to cropmarks. This situation has given us an opportunity to test not only satellite imageries as a source of data but also confront them with results of other non-invasive methods of data acquisition. When working with variety of data we have met several issues which raised problems of interpretation. Consequently, questions related to the cognitive value of remote sensing data appear and should be discussed. What do the data represent? To what extent the imageries, cropmarks or other visualizations represent the past? How should we deal with ambiguity of data? What can we learn from pitfalls in the interpretation of cropmarks, soilmarks etc. to share more Sherlock's methodology rather than run around Don Quixote's delusions?

Phase-change related epigenetic and physiological changes in Pinus radiata D. Don.

Fraga, Mario F; Cañal, Maria Jesús; Rodríguez, Roberto

2002-08-01

DNA methylation and polyamine levels were analysed before and after Pinus radiata D. Don. phase change in order to identify possible molecular and physiological phase markers. Juvenile individuals (without reproductive ability) were characterised by a degree of DNA methylation of 30-35% and a ratio of free polyamines to perchloric acid-soluble polyamine conjugates greater than 1, while mature trees (with reproductive ability) had 60% 5-methylcytosine and a ratio of free polyamines to perchloric acid-soluble polyamine conjugates of less than 1. Results obtained with trees that attained reproductive capacity during the experimental period confirmed that changes in the degree of DNA methylation and polyamine concentrations found among juvenile and mature states come about immediately after the phase change. We suggest that both indicators may be associated with the loss of morphogenic ability during ageing, particularly after phase change, through a number of molecular interactions, which are subsequently discussed.

Don Quijote goes to Hollywood: The rewrite of myth by Charles Chaplin

Directory of Open Access Journals (Sweden)

Esther Bautista Naranjo

2015-12-01

Full Text Available The character of Charlot, created by Charles Chaplin, rewrites the myth of don Quixote in silent movies. While sharing the roots of the picaresque tradition, they represent a harsh criticism of modernity in all its stages. A distinction has to be made between the plain vaudevillesque humor of Charlot in the brief comic strips from 1914 and its tragi-comical shaping in some short films from 1915 up to Modern Times (1936. Beyond their mere physical aspects and their hilarious exploits, an underlying tragic heroism and idealism lead them to uphold all good causes and to support the wronged ones while they also struggle for survival. Charlot combines the comic with the sublime and, as well as the ingenious hidalgo, his soul becomes gradually fuller, deeper and more human. For all these reasons, this character could be regarded as a “quixote” of the big screen.

Full Text Available The article analyzes the state of the Cossack business communities of the Trade Society and MLiTAO during the revolutionary period of 1917. The expediency of scientific research for modern science and practice consists in finding the experience of work of business organizations in the acute crisis conditions of revolutionary time. The documents of the Trading Society of Don Cossacks in 1917 are confused and devoid of the former system. There are no reports of meetings of trustees, reviews of the socio-economic situation on the state of the branches of production. The main activity was aimed at the fulfillment of supplies related to military needs, the organization of self-protection of the military territories, attempts to clarify its own future under the new conditions. The work of the MLiTAO was more practical, the documents were devoted to economic issues and did not affect participation in the revolutionary events of 1917. The materials confirm the existence of an unstable situation, but do not contain information indicating a deep crisis, stopping or malfunctioning of organizations. This is due to the fact that large-scale military operations on the Don began after 1917. Separate cases of transition to a natural exchange or violation of supply contracts can not affirmatively answer the question of feudalization or the nature of the changes in capitalist relations in the region. Don entrepreneurs perceived political transformations as an update of the political system, democratic changes.

Results of geological and environmental observations made by professionals of the Comisión Nacional de Energía Atómica (CNEA) down streams Don Otto uranium mine on the Sunchales creek, from Los Guanacos strait down to the Tonco river mouth, and from river mouth down to narrow pass named Salto Grande, are presented in this report. La Yesera, Las Curtiembres and Los Blanquitos Formations of the Pirgua Subgroup, and Lecho and Yacoraite Formations of the Balbuena Subgroup crops out in that area (Salta Group, Cretaceous- Middle Eocene). Water stream analyses have given uranium contents between 890 μg/L and 1,100 μg/L, and uranium in stream sediments between 4 μg/g and 14 μg/g; radimetric anomalias up to 1,500 c/s in discoloured facies of the Las Curtiembres Formation, and 2,000 c/s in dark pelitic sediments of the Yacoraite Formation. A new zone with uranium traces in Curtiembres Formation belonging to the Pirgua Subgroup has been identified in the Alemanía cretaceous basin, which is stratigraphically similar to Cajoncillo, Las Abritas and El Fraile deposits. Those traces in addition to the other ones localized in the upper third of the Yacoraite Formation would have been originated by the geochemical uranium anomalies in waters and stream sediments by uranium leaching of rocks. The geochemical uranium anomalies in water and sediments are not a consequence of the antropic activity of the uranium mining carried out in Don Otto mine (1961-1982). (authors) [es

Simulating and Simulated Characters, Entangled in Don Quixote

Directory of Open Access Journals (Sweden)

Vicente Pérez de León

2014-12-01

Full Text Available One of the keys for understanding the ruling universe is the nature of the interconnected duality that governs it. It is neither completely monistic, neither absolutely nihilistic, according to the principle of the Platonic symploke (the Sophist 251, 255. The validity of the entanglement between “not everything are monisms” and the fact that reality is not completely “nihilist” will be used as a logic tool to understand the alternation in the understanding of the conclusions of the existences of several of the protagonists of the Quixote. On the one hand, it is the strange case of the suicidal shepherd Grisóstomo, in desperation for his loved Marcela, which is studied in the context of a similar case, the death of Anselmo in The Tale of Ill-advised Curiosity. On the other hand it is the case of the exemplary archetypical death of Don Quixote and his revival in Alonso Quijano “the good”, which presents a similar case of (misunderstanding of the symploke principle. In conclusion, the ontological tragedy arising from not understanding or questioning the Platonic principle of the symploke will contribute to explain the attachment, identification, and nature of the entanglement between reality and fiction in selected cervantine characters. This will be achieved by focusing in both their self-awareness as creative beings and their more or less voluntary inclusion in, or exclusion from, their own simulated realities.

Dissolved organic nitrogen (DON) from atmospheric deposition has been a growing concern in the world and atmospheric nitrogen (N) deposition is increasing quickly in China especially Southeastern China. In our study, DON wet deposition was estimated by collecting and analyzing rainwater samples continuously over eight years (2005-2012) in a typical red-soil farmland ecosystem, Southeast China. Results showed that the volume-weighted-average DON concentration varied from 0.2 to 3.3 mg N L(-1) with an average of 1.2 mg N L(-1). DON flux ranged from 5.7 to 71.6 kg N ha(-1) year(-1) and averaged 19.7 kg N ha(-1) year(-1) which accounted for 34.6% of the total dissolved nitrogen (TDN) in wet deposition during the eight-year period. Analysis of DON concentration and flux, contribution of DON to TDN, rainfall, rain frequency, air temperature and wind frequency and the application of pig manure revealed possible pollution sources. Significant positive linear relation of annual DON flux and usage of pig manure (Pcycle in the red-soil agro-ecosystem in the future.

The AreA transcription factor in Fusarium graminearum regulates the use of some nonpreferred nitrogen sources and secondary metabolite production.

Science.gov (United States)

Giese, Henriette; Sondergaard, Teis Esben; Sørensen, Jens Laurids

2013-01-01

Growth conditions are known to affect the production of secondary metabolites in filamentous fungi. The influence of different nitrogen sources and the transcription factor AreA on the production of mycotoxins in Fusarium graminearum was examined. Growth on glutamine or NH4-sources was poor and asparagine was found to be a preferential nitrogen source for F. graminearum. Deletion of areA led to poor growth on NaNO₃ suggesting its involvement in regulation of the nitrate reduction process. In addition utilization of aspartic acid, histidine, isoleucine, leucine, threonine, tyrosine, and valine as nitrogen sources was shown to depend of a functional AreA. AreA was shown to be required for the production of the mycotoxins deoxynivalenol (DON), zearalenone, and fusarielin H regardless of the nutrient medium. Deletion of nmr, the repressor of AreA under nitrogen sufficient conditions, had little effect on either growth or toxin production. AreA appears to regulate production of some mycotoxins directly or indirectly independent on nitrogen status and plays a role in utilization of certain amino acids.

Polymorphism of young (14-16 years), middle-aged (70-80 years) and old (120-150 years) plants and their seed embryos has been studied using 20 and 10 allozyme loci correspondingly in the population of Pinus pallasiana D. Don from Mountain Crimea. It was revealed that the old-aged trees had significantly lower level of expected heterozygosity than the young plants. The level of observed heterozygosity of embryos of the uneven-aged plants was slightly different among the embryo samples and significantly lower than in the samples of maternal trees. Supernumerary homozygotation of the embryos is caused by low level of cross-pollination in three studied samples of plants (t(m) = 0,537-0,637).

1987-01-01

Following a single oral dose of [ 14 C]deoxynivalenol (2.2 mg of DON, 2.4 μCi/bird) low levels of residues were transmitted to eggs. Maximum radioactivity, which occurred in the first eggs laid after dosing (within 24 h), amounted to 1.9 μg DON-equivalents/60-g egg (0.087% of dose) levels dropped rapidly in ensuing eggs. During daily consumption of DON, administered in spiked feed over a 12-day period (2.2 mg of DON/bird per day for 6 days followed by 2.2 mg of [ 14 C]DON, 1.5 μCi/bird per day for 6 days), radioactivity levels increased with each subsequent egg laid up until the last exposure to the toxin; maximum levels accounted for 4.2 μg DON-equivalents/60-g egg. Residues quickly declined once the birds were switched to clean feed. Results indicate that although residues appear to accumulate in eggs, levels do not persist once the contaminated source is withdrawn. Preliminary analysis of egg material showed only about 10% of radioactivity present could be identified as the parent toxin, DON

Various types and also some variants of alternating direction methods, (A.D.M.), were applied to the solution of the time-dependent heat conduction equation, with source, in region with axial symetry. The results shown that some of the variants perform consistently better than the Classical Cranck-Nicolson method. Having in mind a combination of accuracy, ability to support larg time steps and computational efficiency, the 'alternating direction explicit', (A.D.E.) method appears as the best choice, being the 'alternating direction checkerboard', (A.D.C), method the second best. Additional operations like the exponential transformation or the truncation pos-correction don't seem to be worth, excect for some special cases. (Author) [pt

Full Text Available It has been wrongly thought that foreign countries and their multinational companies hurried to the countries in transition to get benefits by buying facilities and get cheap workforce. There is follow by hidden plan. Getting new knowledge and intellectual properties is at the first place. Secondly, getting new technologies, sorts, patents, highly educated individuals, importing dirty technologies that pollute the environment and only at the third place can be buildings, cheap workforce etc. From security standpoint and the survival of the transitional countries the basic question is how to guard devastating intellect and nonmaterial properties of the country, because without them the country becomes dependent for all times, just from those who has done that in a perfidious and obviously in an intentionally aimed way. There will always be corporations that will try to usurp intangible assets of others, without investing their own scientific, intellectual and workforce and money. This is possible because, throughout the world, they are given possibilities to 'steal' that property from others (with profit at the end.

Artemisinin, an antimalarial compound, at 5 mg/40 ml, was transformed by cell suspension cultures of Catharanthus roseus (L.) G.Don and Lavandula officinalis L. into deoxyartemisinin with yields >78% (3.93 mg deoxyartemisinin from 5 mg artemisinin). Maximum conversion (78.6 and 78%) occurred after 6 and 7 days of adding artemisinin to 20 and 9 days old cultures of C. roseus and L. officinalis, respectively. The procedure was scaled up by and 500 mg artemisinin was transformed into 390 mg deoxyartemisinin. Addition of artemisinin at the beginning of the culture cycle resulted in >50% reduction in dry biomass production with no bioconversion. Conversion of artemisinin occurred intracellularly followed by leaching of the product into the medium.

Anthropogenic Pb affects the environment worldwide. To understand its effect on forest ecosystem, Pb isotope ratios were determined in precipitation, various components of vegetation, the forest floor, soil and parent material in a Japanese cedar (Cryptomeria japonica D. Don) forest stand. The average 206 Pb/ 207 Pb ratio in bulk precipitation was 1.14 ± 0.01 (mean ± SD), whereas that in the subsoil (20-130 cm) was 1.18 ± 0.01. Intermediate ratios ranging from 1.15 to 1.16 were observed in the vegetation, the forest floor, and the surface soil (0-10 cm). Using the 206 Pb/ 207 Pb ratios, the contribution of anthropogenic sources to Pb accumulated in the forest were estimated by the simple binary mixing model. Sixty-two percent of the Pb in the forest floor, 71% in the vegetation, and 55% in the surface soil (0-10 cm) originated from anthropogenic sources, but only 16% in the sub-surface soil (10-20 cm) was anthropogenic. These results suggest that internal Pb cycling occurs mainly between surface soil and vegetation in a Japanese cedar ecosystem, and that anthropogenic Pb strongly influences Pb cycling. Although the Japanese cedar ecosystem has a shallow forest floor, very little atmospherically derived Pb migrated downward over 10 cm in depth

Full Text Available Over his career, Don DeLillo grows to inhabit more complex and critical ideas about politics, capitalism, and strategies for opposition than the remote affect of his earlier work might suggest. As part of this project, he developed an advanced analysis of conditions under the global finance regimes gaining strength in the West. The author's papers at the Harry Ransom Center show that he arrived at this informed position through a program of independent research, his newspaper cuttings from this period vividly demonstrating reflections on the meaning of US global power. Once back in New York, his investment in public intellectual debates on the meaning of "terrorism" led to a characteristic but problematic emphasis on free speech as a political issue. More recently, his work has turned to sophisticated theoretical texts for increasingly subtle ideas about globalization and its opponents.

The aerial components of Meconopsis simplicifolia (D. Don) Walpers are indicated in Bhutanese traditional medicine for treating malaria, coughs and colds, and the infections of the liver, lung and blood. This study is to validate the ethnopharmacological uses of this plant and also identify potent antimalarial drug leads through bioassays of its crude extracts and phytochemical constituents. Meconopsis simplicifolia (D. Don) Walpers was collected from Bhutan and its crude MeOH extract was subjected to acid-base fractionation. Through repeated extractions, separations and spectroscopic analysis, the alkaloids obtained were identified and tested for their antimalarial and cytotoxicity activities. Phytochemical studies resulted in the isolation of one new protoberberine type alkaloid which we named as simplicifolianine and five known alkaloids: protopine, norsanguinarine, dihydrosanguinarine, 6-methoxydihydrosanguinarine and oxysanguinarine. Among the five of the alkaloids tested, simplicifolianine showed the most potent antiplasmodial activities against the Plasmodium falciparum strains, TM4/8.2 (chloroquine-antifolate sensitive strain) and K1CB1 (multidrug resistant strain) with IC50 values of 0.78 μg/mL and 1.29 μg/mL, respectively. The compounds tested did not show any significant cytotoxicity activities against human oral carcinoma KB cells and normal Vero cells of African kidney epithelial cells. This study validated the traditional uses of the plant for the treatment of malaria and identified a new alkaloid, simplicifolianine as a potential antimalarial drug lead. © 2013 Published by Elsevier Ireland Ltd.

Area, length and thickness conservation: Dogma or reality?

Science.gov (United States)

Moretti, Isabelle; Callot, Jean Paul

2012-08-01

The basic assumption of quantitative structural geology is the preservation of material during deformation. However the hypothesis of volume conservation alone does not help to predict past or future geometries and so this assumption is usually translated into bed length in 2D (or area in 3D) and thickness conservation. When subsurface data are missing, geologists may extrapolate surface data to depth using the kink-band approach. These extrapolations, preserving both thicknesses and dips, lead to geometries which are restorable but often erroneous, due to both disharmonic deformation and internal deformation of layers. First, the Bolivian Sub-Andean Zone case is presented to highlight the evolution of the concepts on which balancing is based, and the important role played by a decoupling level in enhancing disharmony. Second, analogue models are analyzed to test the validity of the balancing techniques. Chamberlin's excess area approach is shown to be on average valid. However, neither the length nor the thicknesses are preserved. We propose that in real cases, the length preservation hypothesis during shortening could also be a wrong assumption. If the data are good enough to image the decollement level, the Chamberlin excess area method could be used to compute the bed length changes.

A phantom extinction? New insights into extinction dynamics of the Don-hare Lepus tanaiticus.

The Pleistocene to Holocene transition was accompanied by a worldwide extinction event affecting numerous mammalian species. Several species such as the woolly mammoth and the giant deer survived this extinction wave, only to go extinct a few thousand years later during the Holocene. Another example for such a Holocene extinction is the Don-hare, Lepus tanaiticus, which inhabited the Russian plains during the late glacial. After being slowly replaced by the extant mountain hare (Lepus timidus), it eventually went extinct during the middle Holocene. Here, we report the phylogenetic relationship of L. tanaiticus and L. timidus based on a 339-basepair (bp) fragment of the mitochondrial D-loop. Phylogenetic tree- and network reconstructions do not support L. tanaiticus and L. timidus being different species. Rather, we suggest that the two taxa represent different morphotypes of a single species and the extinction of 'L. tanaiticus' represents the disappearance of a local morphotype rather than the extinction of a species.

Don't be such a scientist talking substance in an age of style

How to relate scientific information in a way that entertains and enlightens? After twenty years as a marine biologist, a Ph.D. from Harvard, a tenured professorship at the University of New Hampshire, and more than twenty published research papers, why is Dr. Randy Olson telling readers, 'Don't Be Such a Scientist'? The hard-earned advice comes from a fifteen-year career transition to filmmaking, culminating in the acclaimed documentaries "Flock of Dodos: The Evolution-Intelligent Design Circus" and "Sizzle: A Global Warming Comedy". In his first book, Olson makes clear what those glued to their microscopes and climate models may not recognize: the general public doesn't speak science. For better or worse, most of us rely not on intellect, but on what Olson terms the organs of mass communication: the heart, the gut, and even 'the lower organs'. Why else do some still question the existence of global warming or evolution when the evidence is irrefutable? Drawing on his own hilarious - and at times humiliating...

Dissolved organic nitrogen (DON) losses from nested artificially drained lowland catchments with contrasting soil types

Science.gov (United States)

Tiemeyer, Bärbel; Kahle, Petra; Lennartz, Bernd

2010-05-01

Artificial drainage is a common practice to improve moisture and aeration conditions of agricultural land. It shortens the residence time of water in the soil and may therefore contribute to the degradation of peatlands as well as to the still elevated level of diffuse pollution of surface water bodies, particularly if flow anomalies like preferential flow cause a further acceleration of water and solute fluxes. Especially in the case of nitrate, artificially drained sub-catchments are found to control the catchment-scale nitrate losses. However, it is frequently found that nitrate losses and nitrogen field balances do not match. At the same time, organic fertilizers are commonly applied and, especially in lowland catchments, organic soils have been drained for agricultural use. Thus, the question arises whether dissolved organic nitrogen (DON) forms an important component of the nitrogen losses from artificially drained catchments. However, in contrast to nitrate and even to dissolved organic carbon (DOC), this component is frequently overlooked, especially in nested catchment studies with different soil types and variable land use. Here, we will present data from a hierarchical water quantity and quality measurement programme in the federal state Mecklenburg-Vorpommern (North-Eastern Germany). The monitoring programme in the pleistocene lowland catchment comprises automatic sampling stations at a collector drain outlet (4.2 ha catchment), at a ditch draining arable land on mineral soils (179 ha), at a ditch mainly draining grassland on organic soils (85 ha) and at a brook with a small rural catchment (15.5 km²) of mixed land use and soil types. At all sampling stations, daily to weekly composite samples were taken, while the discharge and the meteorological data were recorded continuously. Water samples were analyzed for nitrate-nitrogen, ammonium-nitrogen and total nitrogen. We will compare two years: 2006/07 was a very wet year (P = 934 mm) with a high summer

The Delusion of Enchantment in Miguel Cervantes’s Don Quixote and William Shakespeare’s Midsummer Night’s Dream

2017-12-01

Full Text Available The aim of the present article is to investigate the conceptual framework of magic and enchantment in the works of Miguel Cervantes de Saavedra and William Shakespeare. The works chosen for this comparative study are Don Quixote and Midsummer Night’s Dream. Shakespeare and Cervantes portray an ironic vision that may seem comic and grotesque on the surface, but in fact shows a violent and malign world. The portrayal of fantasy and realism parallel with the delusionary aspects of enchantment create an interplay between the ironic mockery and reality as seen through the experiences of the characters themselves. The delusions of enchantment experienced by the protagonists present a flawed world where jealousy, greed and corruption prevail.

Being a part of Chinese as well as ayurdic herbal system, roots of Rumex hastatus D. Don (RH) is highly medicinal, used to regulated blood pressure. It is also reported that the plant is diuretic, laxative, tonic, used against microbial skin diseases, bilious complaints and jaundice. The present study is conducted to evaluate phytochemical, antimicrobial, antitumor and cytotoxic activities of extract obtained from R. hastatus roots. RH roots were powdered and extracted with methanol to get crude extract. Crude extract was further fractioned on the basis of increasing polarity, with n-hexane (HRR), chloroform (CRR), ethyl acetate (ERR), n-butanol (BRR) and residual aqueous fraction (ARR). Methanol extract and its derived fractions were subjected to phytochemical screening and assayed for antibacterial activities via agar well diffusion method. Antifungal activities were checked through agar tube dilution method whereas potato disc assay was employed for the determination of antitumor activity. On the other hand cytotoxic activities were conducted using brine shrimps procedures. The results obtained from phytochemical analysis indicate the presence of alkaloids, anthraquinones, flavonoids and saponins in all the fractions. Most of the plant fractions showed substantial antimicrobial activities, which is in accordance with the spacious use of tested plant samples in primary healthcare center. Fractions of R. hastatus roots for cytotoxicity were tested as an effective cytotoxic was found as BRR > MRR > CRR > ARR > ERR > HRR. Ranking order of fractions of R. hastatus roots for effective antitumor screening was found as MRR > BRR > ARR > CRR > ERR > HRR. These results showed that R. hastatus appeared as an important source for the discovery of new antimicrobial drugs and antitumor agents; verify its traditional uses and its exploitation as therapeutic agent.

Current strategies to control leishmaniasis are mainly based on chemotherapy. However, none of the available drugs can be considered to be ideal to treat this disease. Because of the hydrophobic nature and bioactivities of their components, essential oils (EOs) can be considered as important sources for developing agents against intracellular pathogens, such as Leishmania parasites. In this study, we report the chemical characterization, antileishmanial activities, and cytotoxicity effect of the EO from Pluchea carolinensis (Jacq.) G. Don. (Asteraceae). Chemical analysis revealed that EO from aerial part from P. carolinensis is composed of 44 compounds. The main component was selin-11-en-4α-ol, which made up 51.0%. In vitro antileishmanial studies showed that P. carolinensis EO inhibited the growth of promastigotes (IC 50  = 24.7 ± 7.1 μg/mL) and amastigotes (IC 50  = 6.2 ± 0.1 μg/mL) of Leishmania amazonensis, while cytotoxicity evaluation revealed fivefold higher values than those for the parasites. In a model of experimental cutaneous leishmaniasis in BALB/c mice, five doses of EO at 30 mg/kg by intralesional route demonstrated smaller lesion size and parasite burden (p < 0.05) compared with animals treated with Glucantime® and untreated mice. In conclusion, in vitro and in vivo results showed the potentialities of EO from P. carolinensis with the future possibility of a new alternative in the treatment for leishmaniasis.

Mass media campaigns aimed at influencing lifestyle risk factors are one way that governments are attempting to address chronic disease risk. In Australia, a national campaign aimed at encouraging Australians to make changes in lifestyle-related behaviors was implemented from 2008 to 2011. The first phase, Measure Up (2008-2009), focused on why lifestyle changes are needed by increasing awareness of the link between waist circumference and chronic disease risk. The second phase, Swap It, Don't Stop It (2011), emphasized how adults can change their behaviors. Cross-sectional telephone surveys (after the campaign) were undertaken in July and November 2011 to evaluate the Swap It, Don't Stop It campaign and included measures of campaign awareness and lifestyle-related behavior change. Survey participants (N = 5,097) were similar across the two survey periods. Prompted campaign awareness was 62% (16% for unprompted awareness); females, younger respondents (18-44 years), those in paid employment, and those who spoke English at home were more likely to report prompted/unprompted campaign awareness. Moreover, 16% of survey respondents reported any swapping behavior in the previous 6 months, with the majority (14%) reporting only one swap; younger respondents and those in paid employment were significantly more likely to report having implemented a swapping behavior. The campaign achieved modest population awareness but demonstrated limited effect in terms of nudging behaviors. This evaluation indicates that encouraging swapping behaviors as a prelude to lifestyle change may not result from a mass media campaign alone; a comprehensive multicomponent population approach may be required.

The chemical composition of the essential oil of the Sardinian dwarf curry plant [Helichrysum italicum G. Don ssp. microphyllum (Willd) Nym] was studied. Genetic analysis suggested the presence of two chemotypes; morphological and chemical differences confirmed the presence of two chemotypes (A and B). The maximum yields were 0.18 and 0.04% (v/w) for flowering tops and stems, respectively. The concentrations of nerol and its esters (acetate and propionate), limonene, and linalool reach their highest values during the flowering stage both in flowers and in stems. Besides the essential oil, type B showed an interesting antifungal activity.

Full Text Available Deoxynivalenol (DON is a mycotoxin produced by Fusarium graminearum and its intake represents a severe risk to human and animal health. The objective of this study was to evaluate levels of DON in wheat (Triticum aestivum L. flour from two representative locations of south Brazil. Experiments were carried out in Pato Branco (Paraná and Coxilha (Rio Grande do Sul in a randomized complete block design with three replicates. Levels of DON were measured by high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS/MS. This mycotoxin was detected in 97% of samples, ranging from 200 to 4140 u,g kg-1. Only 17% of samples presented DON beyond of the maximum allowed by the Brazilian Health Surveillance Agency up to the year 2012; even though, Fusarium head blight (FHB epidemics were slight low in the growing season that the study was performed. According to our knowledge, this is the first report showing genetic variability of Brazilian cultivars to DON contamination and some genotypes have potential to be exploited as a source of low accumulation of this toxin.

Full Text Available The use of large cross-section timber for structural purposes has increased in Spain, and knowledge of its properties is strategically necessary. The Spanish visual strength-grading standard UNE 56544 (2011 efficiency applied to large cross-section structural timber was analyzed using a sample of 363 specimens of radiata pine (Pinus radiata D. Don. from the Basque Country and Catalonia, Spain. Different sizes were tested (80 × 120 × 2400 mm3, 150 × 250 × 5600 mm3, 150 × 250 × 4300 mm3, and 200 × 250 × 5000 mm3. Bending strength, modulus of elasticity, and density were obtained, and characteristic values were determined in order to assign strength class according to European standard EN 338 (2010. Knots and twists were the most relevant singularities for visual strength grading. It was concluded that large cross-section Spanish radiata pine timber was suitable for structures, and it was assigned to the C20 strength class.

2018-03-01

This study aimed to evaluate the effects of freezing and cold storage at 4 °C on bulk dissolved organic carbon (DOC) and nitrogen (DON) concentration and SEC fractions determined with size exclusion chromatography (SEC), as well as on spectral properties of dissolved organic matter (DOM) analyzed with fluorescence spectroscopy. In order to account for differences in DOM composition and source we analyzed storage effects for three different sample types, including a lake water sample representing freshwater DOM, a leaf litter leachate of Phragmites australis representing a terrestrial, 'fresh' DOM source and peatland porewater samples. According to our findings one week of cold storage can bias DOC and DON determination. Overall, the determination of DOC and DON concentration with SEC analysis for all three sample types were little susceptible to alterations due to freezing. The findings derived for the sampling locations investigated here may not apply for other sampling locations and/or sample types. However, DOC size fractions and DON concentration of formerly frozen samples should be interpreted with caution when sample concentrations are high. Alteration of some optical properties (HIX and SUVA 254 ) due to freezing were evident, and therefore we recommend immediate analysis of samples for spectral analysis. Copyright © 2017 Elsevier Ltd.

Full Text Available Abstract Background Restoration of rooting competence is important for rejuvenation in Sequoia sempervirens (D. Don Endl and is achieved by repeatedly grafting Sequoia shoots after 16 and 30 years of cultivation in vitro. Results Mass spectrometry-based proteomic analysis revealed three proteins that differentially accumulated in different rejuvenation stages, including oxygen-evolving enhancer protein 2 (OEE2, glycine-rich RNA-binding protein (RNP, and a thaumatin-like protein. OEE2 was found to be phosphorylated and a phosphopeptide (YEDNFDGNSNVSVMVpTPpTDK was identified. Specifically, the protein levels of OEE2 increased as a result of grafting and displayed a higher abundance in plants during the juvenile and rejuvenated stages. Additionally, SsOEE2 displayed the highest expression levels in Sequoia shoots during the juvenile stage and less expression during the adult stage. The expression levels also steadily increased during grafting. Conclusion Our results indicate a positive correlation between the gene and protein expression patterns of SsOEE2 and the rejuvenation process, suggesting that this gene is involved in the rejuvenation of Sequoia sempervirens.

Full Text Available When examining the history of fairy tale iconography in advertising, folklore scholar Donald Haase’s fairy tale encyclopedia compared the Pied Piper of Hamelin to a symbol of advertising who could “play his pipe ever so sweetly and the consumers following him without resisting his charming and manipulative music.” In contrast, a 2012 episode of Mad Men, advertising luminary Don Draper shoots down a shoe commercial pitch featuring Cinderella, calling the idea “cliché”. The temptation for advertisers to rely on fairy tale figures and iconography continues today and many ignore Don’s aversion for cliché because it still gets the job done. However, there are some ads featuring fairy tales which avoid cliché and are truly innovative for their time. I’ll examine how, and for whom, these fairy tale figures have been adapted decade by decade in order to examine popular culture’s commercialized and hypnotic relationship with fairy tales in the most direct format available: television commercials.

Algae cells were the main sources of dissolved organic nitrogen (DON) in raw water with plenty of algae, and ultrasonic pretreatment was one of the algae-controlling methods through the damage of algae cells. However, the variation of DON concentration during the ultrasonic treatment process was not confirmed. Variation of DON concentration during the processes of low frequency ultrasound treatment of Microcystis aeruginosa was investigated. In addition, the effect of sonication on the metabolite concentration, algae cellar activity and the subsequent coagulation performance were discussed. The results showed that after a long duration of ultrasonic (60 s), nearly 90% of the algal cells were damaged and the maximum concentration of DON attained more than 3 mg/L. In order to control the leakage extent of DON, the sonication time should be less than 30 s with power intensity of more than 1.0 W/cm(3). In the mean time, ultrasonic treatment could inhibit the reactivation and the proliferation of algal, keep the algae cell wall integrity and enhance coagulation effectively under the same condition. However, ultrasound frequency had little effect on DON at the frequency range used in this study (20-150 kHz). Copyright © 2015 Elsevier B.V. All rights reserved.

Don't end up in the fields: identity construction among Mexican adolescent immigrants, their parents, and sociocontextual processes.

Science.gov (United States)

Maciel, Jose A; Knudson-Martin, Carmen

2014-10-01

This grounded theory study of 16 Mexican immigrant adolescents and 20 of their parents examines how they construct relational identities within their families, at school, with friends, and in the larger society. Results focus on a core identity bind faced by the adolescents: immigration messages from parents that say, "don't be like me" and the societal message, "you're not like us." Response to this bind was guided by two contrasting sets of identity narratives: Empowering narratives invited an intentional approach to school and life choices. Restricting narratives maintained an ambivalent approach to school and life choices. Resolution of the identity bind was a collective, ongoing process that has implications for Mexican immigrant families and the professionals who work with them. © 2013 American Association for Marriage and Family Therapy.

Nuclear power plant transient diagnostics using artificial neural networks that allow ''don't-know'' classifications

International Nuclear Information System (INIS)

Bartal, Y.; Lin, J.; Uhrig, R.E.

1995-01-01

A nuclear power plant's (NPP's) status is usually monitored by a human operator. Any classifier system used to enhance the operator's capability to diagnose a safety-critical system like an NPP should classify a novel transient as ''don't-know'' if it is not contained within its accumulated knowledge base. In particular, the classifier needs some kind of proximity measure between the new data and its training set. Artificial neural networks have been proposed as NPP classifiers, the most popular ones being the multilayered perceptron (MLP) type. However, MLPs do not have a proximity measure, while learning vector quantization, probabilistic neural networks (PNNs), and some others do. This proximity measure may also serve as an explanation to the classifier's decision in the way that case-based-reasoning expert systems do. The capability of a PNN network as a classifier is demonstrated using simulator data for the three-loop 436-MW(electric) Westinghouse San Onofre unit 1 pressurized water reactor. A transient's classification history is used in an ''evidence accumulation'' technique to enhance a classifier's accuracy as well as its consistency

What consumers don't know about genetically modified food, and how that affects beliefs.

2016-09-01

In the debates surrounding biotechnology and genetically modified (GM) food, data from consumer polls are often presented as evidence for precaution and labeling. But how much do consumers actually know about the issue? New data collected from a nationwide U.S. survey reveal low levels of knowledge and numerous misperceptions about GM food. Nearly equal numbers of consumers prefer mandatory labeling of foods containing DNA as do those preferring mandatory labeling of GM foods. When given the option, the majority of consumers prefer that decisions about GM food be taken out of their hands and be made by experts. After answering a list of questions testing objective knowledge of GM food, subjective, self-reported knowledge declines somewhat, and beliefs about GM food safety increase slightly. Results suggest that consumers think they know more than they actually do about GM food, and queries about GM facts cause respondents to reassess how much they know. The findings question the usefulness of results from opinion polls as a motivation for creating public policy surrounding GM food.-McFadden, B. R., Lusk, J. L.

[The haplomatch program for comparing Y-chromosome STR-haplotypes and its application to the analysis of the origin of Don Cossacks].

STR haplotypes of the Y chromosome are widely used as effective genetic markers in studies of human populations and in forensic DNA analysis. The task often arises to compare the spectrum of haplotypes in individuals or entire populations. Performing this task manually is too laborious and thus unrealistic. We propose an algorithm for counting similarity between STR haplotypes. This algorithm is suitable for massive analyses of samples. It is implemented in the computer program Haplomatch, which makes it possible to find haplotypes that differ from the target haplotype by 0, 1, 2, 3, or more mutational steps. The program may operate in two modes: comparison of individuals and comparison of populations. Flexibility of the program (the possibility of using any external database), its usability (MS Excel spreadsheets are used), and the capability of being applied to other chromosomes and other species could make this software a new useful tool in population genetics and forensic and genealogical studies. The Haplomatch software is freely available on our website www.genofond.ru. The program is applied to studying the gene pool of Cossacks. Experimental analysis of Y-chromosomal diversity in a representative set (N = 131) of Upper Don Cossacks is performed. Analysis of the STR haplotypes detects genetic proximity of Cossacks to East Slavic populations (in particular, to Southern and Central Russians, as well as to Ukrainians), which confirms the hypothesis of the origin of the Cossacks mainly due to immigration from Russia and Ukraine. Also, a small genetic influence of Turkicspeaking Nogais is found, probably caused by their occurrence in the Don Voisko as part of the Tatar layer. No similarities between haplotype spectra of Cossacks and Caucasus populations are found. This case study demonstrates the effectiveness of the Haplomatch software in analyzing large sets of STR haplotypes.

Living in a simulacrum: how TV and the supermarket redefines reality in Don DeLillo’s White Noise

Ghashmari, Ahmad

2010-07-01

Full Text Available This paper examines the impact of simulation, hyperreality, and consumerism on Don Delillo's novel "White Noise". It discusses how the novel pictures technology and mass media as an empire of signs and codes that erase or implode meaning. TV, radio reports and tidbits, and medical imaging devices are intertwined with many aspects of people's lives in this late capitalist culture. Futhermore, the paper will shed some light on the issue of hyperreality which is generated by simulations. We will see how this new type of reality becomes more real than reality itself. Then, the influence of the supermarket and the emergence of consumer culture will be discussed. We will see how production and consumption have gained a new different meaning in this new "superficial" society and how it reshapes people's undestanding and interaction with reality.

Consumption as Sign in Don DeLillo’s Cosmopolis

Full Text Available As one of the foremost American postmodern authors, Don DeLillo tends to focus on construction of postmodern subject’s consciousness through media, technology and consumption. Nevertheless, despite many affinities between Baudrillard and DeLillo, many researches which have been done on his works have failed to theoretically analyze them from Baudrillardian perspective. Although there is affinity between Baudrillard and DeLillo, there is dissimilarity as well. While Baudrillard believes that that there is no escape for individual from the ideology of the system, DeLillo claims that there is hope for change and revolution for the individuals by their action in society, particularly by the means of art, to be more  than a cog in the machine of ideology of system. Baudrillard, as one of the most influential postmodern theorists, defines consumption as organized control of sign and one of the many ways any subject is assimilated in any given society. For Baudrillard the logic of consumption is based on social differentiation. By the logic of social differentiation, individuals distinguish themselves and obtain social prestige and standing through the purchase and use of consumer goods. In his theorization about the concept of need and value, Baudrillard finds Marx’s logics of use value (utility and functionality and exchange value (economic value inadequate to include the whole function of an object and adds the logic of sign value. Baudrillard asserts that in consumption economic exchange value (money is transformed into sign exchange value (prestige, etc.; yet this functioning is maintained by the use value. The only way out of this dilemma, Baudrillard claims, is to return to symbolic exchange which is neither a conception nor an agency, but an act of exchange and a social relation and the only approach to real human communication and understanding. Therefore this research attempts to highlights those affinities in DeLillo’s first post-9

Shattering Man’s Fundamental Assumptions in Don DeLillo’s Falling Man

Full Text Available The present study addresses effects of traumatic events such as the September 11 attacks on victims’ fundamental assumptions. These beliefs or assumptions provide individuals with expectations about the world and their sense of self-worth. Thus, they ground people’s sense of security, stability, and orientation. The September 11 terrorist attacks in the U.S.A. were very tragic for Americans because this fundamentally changed their understandings about many aspects in life. The attacks led many individuals to build new kind of beliefs and assumptions about themselves and the world. Many writers have written about the human ordeals that followed this incident. Don DeLillo’s Falling Man reflects the traumatic repercussions of this disaster on Americans’ fundamental assumptions. The objective of this study is to examine the novel from the traumatic perspective that has afflicted the victims’ fundamental understandings of the world and the self. Individuals’ fundamental understandings could be changed or modified due to exposure to certain types of events like war, terrorism, political violence or even the sense of alienation. The Assumptive World theory of Ronnie Janoff-Bulman will be used as a framework to study the traumatic experience of the characters in Falling Man. The significance of the study lies in providing a new perception to the field of trauma that can help trauma victims to adopt alternative assumptions or reshape their previous ones to heal from traumatic effects.

DOC and DON Dynamics along the Bagmati Drainage Network in Kathmandu Valley

Bhatt, M. P.; McDowell, W. H.

2005-05-01

We studied organic matter dynamics and inorganic chemistry of the Bagmati River in Kathmandu valley, Nepal, to understand the influence of human and geochemical processes on chemical loads along the drainage system. Population density appears to be the most fundamental control on the chemistry of surface waters within the Bagmati drainage system. DOC concentration increases 10-fold with distance downstream (from 2.38 to 23.95 mg/L) and shows a strong relationship with human population density. The composition of river water (nutrients, Cl) suggests that sewage effluent to the river has a major effect on water quality. Concentrations were highest during summer, and lowest during the winter monsoon season. In contrast to DOC, DON concentration shows surprisingly little variation, and tends to decrease in concentration with distance downstream. Ammonium contributes almost all nitrogen in the total dissolved nitrogen fraction and the concentration of nitrate is negligible, probably due to rapid denitrification within the stream channel under relatively low-oxygen conditions. Decreases in sulfate along the stream channel may also be due to the reduction of sulfate to sulfide due to the heavy organic matter loading. Water quality is unacceptable for any use and the whole ecosystem is severely affected within the urban areas. Based on a comparison of downstream and upstream water quality, it appears that human activities along the Bagmati, principally inputs of human sewage, are largely responsible for the changes in surface water chemistry within Kathmandu valley.

The biovariability of Helichrysum italicum (Roth) Don grown wild in Calabria and Sardinia (Italy) was reported. This species has been characterized through the detection, isolation and quantitative evaluation of chemical markers (alpha-terpinolene, trans-cariophyllene and neryl acetate) by GC and GC-MS. Antioxidant activity of the methanolic H. italicum extracts using DPPH and beta-carotene bleaching test showed that the Calabrian samples were more active than those from Sardinia. The antibacterial activity of all extracts evidenced the best performance on the Gram positive bacteria particularly on Micrococcus luteus. Moreover, antifungal activity of all extracts was also tested evidencing important results particularly on the phytopathogene fungus Pythium ultimum. In general, as regards the antifungal activity, the extracts from Sardinia were more active than those from Calabria. The phytochemical analysis and the biological activity data suggested a possible use of these plant matrices in alimentary, cosmetic and pharmaceutical fields.

In the future, toward death: Finance capitalism and security in Don DeLillo’s ‘Cosmopolis’

Directory of Open Access Journals (Sweden)

Johannes Voelz

2018-05-01

Full Text Available This article develops a reading of Don DeLillo’s novel Cosmopolis that differentiates between two thematic and poetological axes running through the text. On the one hand, Cosmopolis explores the future-fixation of the risk regime of finance capitalism; on the other, it stages scenes of insecurity that physically threaten the protagonist and his world. Insecurity, the article argues, is a condition that throughout the text increasingly gains in appeal because it promises to offer an alternative to a world of managed risk. The concern with security emphasizes finitude and mortality, thus enabling a turn to existential matters that the virtual abstractions of finance have seemingly made inaccessible. While proposing an opposition between a logic of risk based on virtuality and a logic of (insecurity based on authenticity, DeLillo’s novel also suggests that it is impossible to break out of the logic of risk management pervading late modernity. The appeal of (insecurity articulated in Cosmopolis rather lies in the promise to existentially revitalize life within the confines of financialized capitalism.

vitreous ripening, also the accumulation of significant quantities of DON-3-glucoside (DON-3G, a product of DON glycosylation, was detected, with decreasing levels in straw, crown, stems and kernels. The presence of DON and DON-3G in heads and kernels without the occurrence of F. graminearum may be explained by their water solubility that could facilitate their translocation from stem to heads and kernels. The presence of DON-3G at levels 23 times higher than DON in the heads at milk stage without the occurrence of F. graminearum may indicate that an active glycosylation of DON also occurs in the head tissues. Finally, the high levels of DON accumulated in straws are worrisome since they represent additional sources of mycotoxin for livestock.

The results indicated that for the production of seedlings of this species, the substrate soil + vermiculite showed the best development of the seedlings in 120 cm3 containers.

Use of 15N-labelled nitrogen deposition to quantify the source of nitrogen in runoff at a coniferous-forested catchment at Gardsjoen, Sweden

To determine the source of dissolved inorganic nitrogen (N) in runoff, approx. 35 kg N enriched with the stable isotope 15 N (2110 per mille δ 15 N) was added to a mature coniferous forested catchment for one whole year. The total N input was approx. 50 kg ha -1 year -1 . The enrichment study was part of a long-term whole-catchment ammonium nitrate addition experiment at Gardsjoen, Sweden. The 15 N concentrations in precipitation, throughfall, runoff and upper forest floor were measured prior to, during, and 3-9 years following the 15 N addition. During the year of the 15 N addition the δ 15 N level in runoff largely reflected the level in incoming N, indicating that the leached NO 3 - came predominantly from precipitation. Only 1.1% of the incoming N was lost during the year of the tracer addition. The cumulative loss of tracer N over a 10-year period was only 3.9% as DIN and 1.1% as DON. - 15 N tracer addition showed that initially the main source of NO 3 - in runoff was N from atmospheric deposition

This study compared the use of ultrasound-assisted supercritical CO 2 (USC-CO 2 ) extraction to obtain apigenin-rich extracts from Scutellaria barbata D. Don with that of conventional supercritical CO 2 (SC-CO 2 ) extraction and heat-reflux extraction (HRE), conducted in parallel. This green procedure yielded 20.1% and 31.6% more apigenin than conventional SC-CO 2 extraction and HRE, respectively. Moreover, the extraction time required by the USC-CO 2 procedure, which used milder conditions, was approximately 1.9 times and 2.4 times shorter than that required by conventional SC-CO 2 extraction and HRE, respectively. Furthermore, the theoretical solubility of apigenin in the supercritical fluid system was obtained from the USC-CO 2 dynamic extraction curves and was in good agreement with the calculated values for the three empirical density-based models. The second-order kinetics model was further applied to evaluate the kinetics of USC-CO 2 extraction. The results demonstrated that the selected model allowed the evaluation of the extraction rate and extent of USC-CO 2 extraction. Copyright © 2017 Elsevier Ltd. All rights reserved.

The radial growth of conifer trees proceeds from the dynamics of a merismatic tissue called vascular cambium or cambium. Cambium is a thin layer of active proliferating cells. The purpose of this paper was to model the main characteristics of cambial activity and its consecutive radial growth. Cell growth is under the control of the auxin hormone indole-3-acetic. The model is composed of a discrete part, which accounts for cellular proliferation, and a continuous part involving the transport of auxin. Cambium is modeled in a two-dimensional cross-section by a cellular automaton that describes the set of all its constitutive cells. Proliferation is defined as growth and division of cambial cells under neighbouring constraints, which can eliminate some cells from the cambium. The cell-growth rate is determined from auxin concentration, calculated with the continuous model. We studied the integration of each elementary cambial cell activity into the global coherent movement of macroscopic morphogenesis. Cases of normal and abnormal growth of Pinus radiata (D. Don) are modelled. Abnormal growth includes deformed trees where gravity influences auxin transport, producing heterogeneous radial growth. Cross-sectional microscopic views are also provided to validate the model's hypothesis and results.

"Don't know" answers concerning somatic disease status should not be regarded as "no" responses

Baumeister, Harald

2008-06-01

Full Text Available Background: With regard to patients' self-reported somatic diseases some researchers transformed “don't know (DK” responses into “no” responses. The present study examines the appropriateness of this procedure. Methods: Analyses were based on the nationally representative German National Health Interview and Examination Survey (GHS, which assessed both self-reported diseases and physician-diagnosed diseases (N = 7124. Prevalence rates of persons’ DK responses and the corresponding prevalences of physicians’ diagnoses were calculated for persons with hypertension, coronary heart disease (CHD, heart failure, asthma, chronic bronchitis, thyroid disease, diabetes, cancer, gout, arthrosis, arthritis and osteoporosis. Correlates of physicians' diagnosed diseases of DK cases are reported. Results: Between 1.6% and 9.8% of the participants responded with DK to the question of whether they have the disease. In 3.7% to 29.5% of DK cases, the physicians did regard the respective disease as being present. With regard to persons who responded with DK, the probability of a physicians' diagnosis was increased in the case of increased age and a higher number of somatic comorbidities. Conclusion: The procedure of transforming DK responses into “no” answers does not appear to be recommendable.

As we all know too well, building up a collaborative community around a software infrastructure is not easy. Besides recruiting enthusiasts to work as part of it, mostly for free, to succeed you also need to overcome a number of technical, sociological, and, to our surprise, some political hurdles. The ALMA Common Software (ACS) was developed at ESO and partner institutions over the course of more than 10 years. While it was mainly intended for the ALMA Observatory, it was early on thought as a generic distributed control framework. ACS has been periodically released to the public through an LGPL license, which encouraged around a dozen non-ALMA institutions to make use of ACS for both industrial and educational applications. In recent years, the Cherenkov Telescope Array and the LLAMA Observatory have also decided to adopt the framework for their own control systems. The aim of the "ACS Community" is to support independent initiatives in making use of the ACS framework and to further contribute to its development. The Community provides access to a growing network of volunteers eager to develop ACS in areas that are not necessarily in ALMA's interests, and/or were not within the original system scope. Current examples are: support for additional OS platforms, extension of supported hardware interfaces, a public code repository and a build farm. The ACS Community makes use of existing collaborations with Chilean and Brazilian universities, reaching out to promising engineers in the making. At the same time, projects actively using ACS have committed valuable resources to assist the Community's work. Well established training programs like the ACS Workshops are also being continued through the Community's work. This paper aims to give a detailed account of the ongoing (second) journey towards establishing a world-wide open source collaboration around ACS. The ACS Community is growing into a horizontal partnership across a decentralized and diversified group of

Full Text Available The mycotoxins associated with specific Fusarium fungal infections of grains are a threat to global food and feed security. These fungal infestations are referred to as Fusarium Head Blight (FHB and lead to Fusarium Damaged Kernels (FDK. Incidence of FDK >0.25% will lower the grade, with a tolerance of 5% FDK for export feed grain. During infestation, the fungi can produce a variety of mycotoxins, the most common being deoxynivalenol (DON. Fusarium Damaged Kernels have been associated with reduced crude protein (CP, lowering nutritional, functional and grade value. New technology has been developed using Near Infrared Transmittance (NIT spectra that estimate CP of individual kernels of wheat, barley and durum. Our objective is to evaluate the technology's capability to reduce FDK and DON of downgraded wheat and ability to salvage high quality safe kernels. In five FDK downgraded sources of wheat, the lowest 20% CP kernels had significantly increased FDK and DON with the high CP fractions having decreased FDK and DON, thousand kernel weights (TKW and bushel weight (Bu. Strong positive correlations were observed between FDK and DON (r = 0.90; FDK and grade (r = 0.62 and DON and grade (r = 0.62. Negative correlations were observed between FDK and DON with CP (r = −0.27 and −0.32; TKW (r = −0.45 and −0.54 and Bu (r = −0.79 and −0.74. Results show improved quality and value of Fusarium downgraded grain using this technology.

The objective of this study was to investigate the effects of breathing frequency and flow rate on the total inward leakage (TIL) of an elastomeric half-mask donned on an advanced manikin headform and challenged with combustion aerosols. An elastomeric half-mask respirator equipped with P100 filters was donned on an advanced manikin headform covered with life-like soft skin and challenged with aerosols originated by burning three materials: wood, paper, and plastic (polyethylene). TIL was determined as the ratio of aerosol concentrations inside (C in) and outside (C out) of the respirator (C in/C out) measured with a nanoparticle spectrometer operating in the particle size range of 20-200nm. The testing was performed under three cyclic breathing flows [mean inspiratory flow (MIF) of 30, 55, and 85 l/min] and five breathing frequencies (10, 15, 20, 25, and 30 breaths/min). A completely randomized factorial study design was chosen with four replicates for each combination of breathing flow rate and frequency. Particle size, MIF, and combustion material had significant (P plastic aerosol produced higher mean TIL values than wood and paper aerosols. The effect of the breathing frequency was complex. When analyzed using all combustion aerosols and MIFs (pooled data), breathing frequency did not significantly (P = 0.08) affect TIL. However, once the data were stratified according to combustion aerosol and MIF, the effect of breathing frequency became significant (P plastic combustion aerosol. The effect of breathing frequency on TIL is less significant than the effects of combustion aerosol and breathing flow rate for the tested elastomeric half-mask respirator. The greatest TIL occurred when challenged with plastic aerosol at 30 l/min and at a breathing frequency of 30 breaths/min.

Full Text Available Among the early medieval antiquities of the Lower Don basin, two funerary complexes are of interest. One was accidentally discovered in 1914 in the Cossack village Nazarov, and the other – near the settlement Bolshaya Orlovka in 1972. Based upon the Byzantine solidities, found in their inventory, they date from the first half of the 8th century. Two iron lamps in the form of bowls on a high leg were found in these funerary complexes along with a diverse and prestigious inventory. In addition to them, two iron composite altars of different sizes were found in the Bolshaya Orlovka. In the early medieval burial mound near the Brusyana village in the Volga region a solidcast iron lamp-altar was found, consisting of a bowl in the form of a concave disc on a long leg, which was welded in the center of a hexagonal bowl with low straight sides and a flat bottom. Short legs are located at its three corners. Typologically Brusian discovery was later then those of the Nazarov and the Bolshaya Orlovka. It unites the altar, consisting of threebowls with low straight bows and a flat bottom, with a lamp. Short legs are located at its three corners of the bowls. These were specific bowls that were used to carry fire during rituals of steppe nomads who had close cultural contacts with the fire worshipers of Sasanid Iran, whose population professed Zoroastrianism.

Full Text Available The objectives of this study were to determine the variety and amount of various functional components in Scutellaria barbata D. Don as well as study their anti-inflammatory activity on RAW 264.7 cells. Both ethanol and ethyl acetate extracts were shown to contain the functional components including phenolics, flavonoids, chlorophylls, and carotenoids, with the former mainly composed of phenolics and flavonoids, and the latter of carotenoids and chlorophylls. Both extracts could significantly inhibit (p < 0.05 the production of lipopolysaccharide-induced nitric oxide, prostaglandin E2, interlukin-6, and interlukin-1β, as well as the expressions of phosphor extracellular signal-regulated kinase and phosphor-c-Jun N-terminal kinase (p-JNK, but failed to retard tumor necrosis factor-α expression. Both ethanol and ethyl acetate extracts had a dose-dependent anti-inflammatory activity on RAW 264.7 cells. Furthermore, the anti-inflammatory efficiency can be varied for both ethanol and ethyl acetate extracts, which can be attributed to the presence of different varieties and amounts of functional components, as mentioned above. This finding suggested that S. Barbata extract may be used as an anti-inflammatory agent for possible future biomedical application.

Full Text Available The Acacia genus has presented various secondary metabolites, such as tannins, flavonoids, alkaloids and gums. Preparations from different species have been applied for diabetes, gastrointestinal disorders and inflammatory diseases in the traditional medicine and have demonstrated cytotoxic, antimicrobial and antiparasitic activities. Acacia podalyriifolia A. Cunn. ex G. Don (Fabaceae is a small wood, indigenous to Australia and cultivated worldwide for its ornamental feature. This work aimed to characterize the anatomy of the phyllode and stem, in order to contribute to the species identification. The botanical material was fixed, sectioned and prepared according to usual light and scanning microtechniques. The epidermal cells, in surface view, are polygonal and coated with striate and thick cuticle, and filaments of epicuticular wax. Paracytic stomata and unicellular non-glandular trichomes are seen. Palisade and ground parenchymas, and minor collateral bundles with xylem directed alternately to upper and lower sides occur in the blade. The midrib shows two collateral bundles facing each other. The stem, in incipient secondary growth, exhibits epidermis, annular collenchyma, sclerenchymatic sheath and collateral vascular organization. Cells containing phenolic compounds and prisms of calcium oxalate are observed.

'Don't save her'- Sigmund Freud meets Project Pat: the rescue motif in hip-hop.

Science.gov (United States)

Fulmer, Richard H

2008-08-01

Freud originally explicated the dynamics of rescue wishes by describing men who fell in love with prostitutes. He saw this attempt at attachment as driven by the man's wish to repay his parents for giving him life. Many subsequent writers shift this emphasis, seeing rescue wishes as motivated by aggressive oedipal competition with the father. This article highlights the attachment aspects of Freud's original conception and traces how writers in the last three decades use the family romance rather than Oedipus as a model to view rescue wishes as having a more tender aspect. Rescue wishes are especially characteristic of the developmental stage of young adulthood. They at once attempt to repay the parental debt the young adult feels and serve as practice for the vicissitudes of the couple bond and the benign sacrifices of parenthood. Popular culture contains many vivid examples of Freud 's original description of the rescue-motif. A detailed examination of the rap song, Don't save her, demonstrates all the elements of Freud's original conception and the interpersonal risks of the rescue relationship. Three additional rap songs by other artists are briefly analyzed to show the extensive occurrence of the wish to rescue and its psychic and interpersonal dangers.

Full Text Available Abstract Salacia crassifolia (Mart. Ex. Schult. G. Don. is a bush which belongs to Celastraceae family and occurs specially in Brazilian Cerrado. Its leaves, stem, seeds and fruits are popularly used for several medicinal purposes, such as antitumoral, antirheumatic, anti-inflammatory and antimicrobial. In this study, the mutagenic and antimutagenic activities of S. crassifolia stem bark fractions (hexane, ethyl acetate and hydroalcoholic were evaluated by the Ames mutagenicity assay in Salmonella typhimurium TA98 and TA100 strains. By the obtained results, all S. crassifolia fractions did not significantly increase the number of prototrophic revertants for histidine (His+ in both S. typhimurium strains tested (p > 0.05, suggesting absence of mutagenicity. Regarding antimutagenicity, the fractions ethyl acetate and hydroalcoholic significantly decreased the number of His+ revertants colonies induced by positive control for strain TA98 (p < 0.05, demonstrating protection against mutagenicity induced by 4-nitroquinolile1-oxide, whereas the hexane fraction did not show antimutagenic effect in this strain. In the TA100 strain, all fractions of S. crassifolia protected DNA against the harmful action of sodium azide, and the hexane fraction exhibited the greatest protection in this work. Thus, it’s possible conclude that the fractions of S. crassifolia tested in this study could be used in chemoprevention.

Full Text Available Aim The present paper aims at highlithing the new dynamics of comparison and exchange between literature and arts. It assumes the idea of a literature centred on the relations between text and context, bent on exhalting its "social" disposition. Then it deals with the subject of the work's originality in terms of identitary pact constantly renegotiated with works belonging to other semiologic themes. In this perspective, this article briefly investigates the complex relation between Don De Lillo's and Jean-Luc Godard's works. Methodology The analytic approach moves between comparative literature and cultural criticism, in a very well-known field in the area of traditional literary studies and a very important sector in the structuration of contemporary imaginary: the relation between literature and cinema. The methodology adopted employs the comparative dynamics typical of text semiotcs, to underline exchange categories, among different languages and codes, which prove to be flowing, open and constantly changing. Results The article highlights and explores new possibilities in the relation between cinema and literature, investigating them on the basis of the present observations on the notion of text; it also explains the urgency of a semantic reassessment of the concept of "work's originality" in the contemporary semiosphere.

While surface gravity can be measured from asteroseismology, asteroseismology cannot be applied to every star. Surface gravity is a critical stellar parameter because it can be used to calculate the radii of stars, which is important in the characterization of host stars of exoplanets. Here we present spectroscopic observations from ESPaDOnS on the Canada-France-Hawaii Telescope of 172 benchmark “gold standard” stars observed by the NASA Kepler Mission for which densities and surface gravities have been precisely measured using asteroseismology. The goal is to discover an empirical correlation between the equivalent width of the spectral lines in the infrared Ca II triplet region (from 8470 to 8710 angstroms) against surface gravity and other stellar parameters, such as effective temperature and metallicity. The Mg I line at 8736 angstroms has the best potential to be an indicator of surface gravity so far out of the spectral lines in this region with equivalent width increasing slightly as a function of surface gravity; however, degeneracies with effective temperature and metallicity need to be explored further. If a true indicator for surface gravity can be found, then it can to be applied to the R~11000 Gaia radial velocity spectra, which will be released for millions of stars over the coming years.

Alzheimer's disease is a severe neurodegenerative disease affecting elder worldwide and closely related to the neurotoxicity induced by amyloid β. To find efficient therapeutics, we have investigated the protective effects of cedrin from Cedrus deodara (Roxb.) G. Don on PC12 cells against the neurotoxicity induced by amyloid β 1-42 . The results have shown the viability of PC12 cells injured by amyloid β 1-42 can be improved by cedrin. Cedrin can reduce reacrive oxygen species overproduction, increase the activity of superoxide dismutase and decrease malondialdehyde content. Meanwhile, the loss of mitochondrial membrane potential and mitochondrial permeability transition pore opening in PC12 cells, and elevated Caspase-3 activity, downregulated Bcl-2 and upregulated Bax are meliorated. These results demonstrate the protective effect of cedrin is related to the inhibition of oxidative stress, improvement of mitochondrial dysfunction and suppression of apoptosis. This investigation gives evidences for the application of cedrin in practice and further investigation in vivo.

Investigation of a superthermal ultracold neutron source based on a solid deuterium converter for the TRIGA Mainz reactor

Research in fundamental physics with the free neutron is one of the key tools for testing the Standard Model at low energies. Most prominent goals in this field are the search for a neutron electric dipole moment (EDM) and the measurement of the neutron lifetime. Significant improvements of the experimental performance using ultracold neutrons (UCN) require reduction of both systematic and statistical errors.The development and construction of new UCN sources based on the superthermal concept is therefore an important step for the success of future fundamental physics with ultracold neutrons. Significant enhancement of today available UCN densities strongly correlates with an efficient use of an UCN converter material. The UCN converter here is to be understood as a medium which reduces the velocity of cold neutrons (CN, velocity of about 600 m/s) to the velocity of UCN (velocity of about 6 m/s).Several big research centers around the world are presently planning or constructing new superthermal UCN sources, which are mainly based on the use of either solid deuterium or superfluid helium as UCN converter.Thanks to the idea of Yu.Pokotilovsky, there exists the opportunity to build competitive UCN sources also at small research reactors of the TRIGA type. Of course these smaller facilities don't promise high UCN densities of several 1000 UCN/cm 3 , but they are able to provide densities around 100 UCN/cm 3 for experiments.In the context of this thesis, it was possible to demonstrate succesfully the feasibility of a superthermal UCN source at the tangential beamport C of the research reactor TRIGA Mainz. Based on a prototype for the future UCN source at the Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRMII) in Munich, which was planned and built in collaboration with the Technical University of Munich, further investigations and improvements were done and are presented in this thesis.

Climate as possible reproductive barrier in Pinus radiata (D. Don interspecific hybridisation

2017-12-01

Full Text Available Historically, interspecific hybridisation with Pinus radiata D. Don had limited success. The effect of environmental conditions and position of pollination bags in the tree were investigated as possible hybridisation barriers. The study was conducted in a P. radiata seed orchard in the Southern Cape (South Africa. Field data were compared to the climatic conditions at natural and commercial provenances of seven Mesoamerican Pinus species identified as possible hybrid partners. In vitro pollen studies were used to confirm whether interspecific crosses with P. radiata might be feasible within predefined climatic parameters. The temperature ranges for both top and northern side of P. radiata pine trees in the seed orchard was similar to the natural distribution of P. radiata, P. elliottii Engelm. and P. taeda L. in the USA. Results suggested that pollen of P. elliottii and P. taeda might be more suited to result in the successful pollination of P. radiata than the other Mesoamerican pine species tested in this study.  Furthermore, the combination of minimum temperature and precipitation also showed a closer correlation to successful hybridisation with P. radiata for both P. elliotii and P. taeda. However, pollen tube elongation studies did not support these results, suggesting that mean temperature might not be the only determining factor of hybridisation success. Three circadian temperature models that mimic natural conditions were developed for Karatara and Sabie (Tweefontein, Witklip and Spitskop.  These models will be tested in future in vitro studies to further evaluate temperature fluctuations between day and night regimes as a possible reproductive barrier limiting hybridisation success between P. radiata and other Mesoamerican pine species.

A new trend in research funding has emerged: directed philanthropy, in which the donor plays an active, hands-on role in managing the research by applying a "business model." Although such efforts now represent only a small portion of foundation funding, they have potentially far-reaching implications because (1) the approach of using a business model is being applied more broadly and (2) the success or failure of these efforts may portend the fate of larger translational efforts. The author conducted interviews with Scott Johnson of the Myelin Repair Foundation and Don Listwin of the Canary Foundation in the fall of 2006.

Yandan, H.; Jun, L.; Jin, X.; Tianyun, W.

2017-12-01

Geological disasters occur with the stress changes of subsurface medium. Since the stress changes slowly in the deep earth where only seismic wave can reach, monitoring the changes with repeatable seismic sources, ambient seismic noise and artificial sources has become a hot topic in seismology. The Fujian Earthquake Agency successfully constructed the Air-gun artificial source system and carried out over 6000 shots in six reservoirs. The correlation coefficient of signals can reach up to 0.99. Besides an excellent source, high recognition ability of seismic wave changes is required. It is common to use time delay estimation method based on cross-correlation to recognize the velocity changes. We investigate the accuracy of time delay detection of Air-gun source signals. Suppose that the medium does not change in a short time, we changed the explosion conditions of the air-gun array and recognized the subtle changes of signals by the time delay estimation method: (1) we changed the excitation depth from 8m to 30m, and found that the arriving time of bubble pulses advanced nearly 90ms. The results are quite consistent with the records of the OBS on the bottom of reservoir; (2) we changed the firing pressure from 800Psi to 2000Psi, and found that the bubble pulses were quite different but now we don't have any suitable numerical model to fit the changes; (3) we changed the excitation position of the air-gun, and divided the changed distance between the Air-gun and the near-shore seismograph by the corresponding changed travelling time. Then we got a velocity of 1.5km/s, which equals to the sound speed in water; (4) we controlled the microsecond of explosion moment from 0ms to 9ms, and counted the time delays of waveforms. Results are quite consistent with the theoretical value; (5) we changed the explosion mode, and quantitatively recognized the 0.1ms changes of the signal travel time. Our experiments show that the method is of high precision that can recognize the

Don Quijote et Dulcinea, ou quand l’univers fictionnel interroge la réalité de l’amour

2009-02-01

Full Text Available Vaste mise en miroir d’une fiction qui n’en finit pas d’interroger son rapport ambigu au réel, le chef d’œuvre de Cervantès place le mouvement dialectique entre univers fictionnel et réalité au cœur même de son écriture. Au sein de cette dialectique, l’amour multiplement fictionnel de don Quichotte pour Dulcinée joue cependant un rôle majeur que ce travail se propose d’examiner. Lieu d’épanouissement privilégié d’un questionnement du rapport entre fiction et réalité, la mise en écriture de cet amour participe en effet de la vaste entreprise de révision des concepts menée par la pensée humaniste : c’est une exploration de la notion même d’amour, de sa réalité, de sa vérité, que permet le voyage au pays de l’amour auquel le Quichotte de Cervantès invite le lecteur.

Periwinkle (Catharanthus roseus (L.) G. Don) is a medicinal plant containing about 130 types of alkaloids that have important pharmacological effects. Ajmalicine in periwinkle root is an antihypertensive drug used in treatment of high blood pressure. Adventitious roots obtained from periwinkle leaves of in vitro shoots grew well in quarter-strength MS medium supplemented with 0.3 mg/l IBA and 20 g/l sucrose. Dark condition was more suitable for root growth than light. However, callus formation also took place in addition to the growth of adventitious roots. Temporary immersion system was applied in the culture of adventitious roots in order to reduce the callus growth rate formed in shake flask cultures. The highest growth index of roots was achieved using the system with 5-min immersion every 45 min (1.676 ± 0.041). The roots cultured in this system grew well without callus formation. Ajmalicine content was highest in the roots cultured with 5-min immersion every 180 min (950 μg/g dry weight).

Full Text Available ABSTRACT The phytochemical study of the extract leaves from Maytenus distichophylla Mart. and Salacia crassifolia (Mart. ex Schult. G. Don, Celastraceae, resulted in the isolation of 3-oxofriedelane, 3β-hydroxyfriedelane, 3β,24-dihydroxyfriedelane, 3-oxo-28,29-dihydroxyfriedelane, two mixtures of pentacyclic triterpenes (α-amyrin with β-amyrin and 3β-stearyloxy-urs-12-ene with 3β-stearyloxy-olean-12-ene, 3β-palmityloxy-urs-12-ene, the steroid β-sitosterol and its glycosylated derivative β-glucosyl-β-sitosterol, tritriacontanoic acid and the natural polymer gutta percha. The chemical structures of these constituents were established by IR, 1H and 13C NMR spectral data. Crude extracts, the mixtures of triterpenes and the isolated constituents were subjected to in vitro acetylcholinesterase inhibitory evaluation. Acetylcholinesterase inhibitory effect was observed for crude chloroform extract leaves from M. distichophylla (100% and S. crassifolia (97.93 ± 5.63% and for the triterpenes 3β,24-dihydroxyfriedelane (99.05 ± 1.12%, 3-oxo-28,29-dihydroxyfriedelane (90.59 ± 3.76% and 3β-palmityloxy-urs-12-ene (97.93 ± 1.47%. The percent inhibitions induced by these natural products were very similar to those produced by physostigmine (93.94 ± 2.10% a standard acetylcholinesterase inhibitor. Therefore, these results open perspectives for the use of these species as source of compounds with similar physostigmine pharmacological effect.

The material balance of carbonization products (wood-gas, wood-vinegar, wood-tar and charcoal) prepared from the sapwood and the heartwood of Sugi (Cryptomeria japonica D. Don) at various temperatures was determined. The evolution of both carbon monoxide and carbon dioxide mainly occurred at the carbonization temperature below 600 degree C and that of hydrogen and methane at 600-800 degree C. Total yield of the wood-vinegar and the wood-tar was almost constant at 500-800 degree C. On the other hand, the yield of the charcoal decreased because of the evolution of the wood gas with an increase in carbonization temperature. The wood-vinegars prepared at the temperature over 400 degree C were found to consist of carboxylic acids such as acetic acid and propionic acid, methanol, acetone, furans, alkylphenols, guaiacols, cyclotene and maltol by capillary gas chromatography. Since the constituent varieties and contents of the wood-vinegars prepared at both 400 degree C and 800 degree C were very similar each other, the wood-vinegar of Sugi wood chiefly produced below 400 degree C. FT-IR spectra of the charcoals showed the generation of carbonyl and olefin groups at 300-400 degree C and then the formation of aromatic rings along with the disappearance of carbonyl groups over 600 degree C. The production of radical species in the charcoals carbonized at 300-600 degree C was observed by ESR, on the contrary, the charcoals carbonized over 700 degree C were inactive. The specific surface area and the pore volume of the charcoal of Sugi sapwood increased with an increase in carbonization temperature. The pH of charcoal-dispersed aqueous solution increased with an increase in carbonization temperature. The high adsorptive activity of the charcoal carbonized at 400 degree C for ammonia gas and that at 800 degree C for hydrogen sulfide gas seemed to be dependent on acidic and basic properties of the charcoals, respectively.

A phytochemical study was performed on Arundina graminifolia (D.Don) Hochr. by silica gel column and semi-preparative HPLC, and ten stilbenoids were obtained. Their structures were elucidated by NMR and MS spectra and identified as 7-hydroxy-2,4-dimethoxy-9,10-dihydrophenanthrene (1), 4,7-dihydroxy-2-methoxy-9,10-dihydrophenanthrene (2), 2,7-dihydroxy-4-methoxy-9,10-dihydrophenanthrene (3), 3,3’-dihydroxy-5-methoxy-bibenzyl (4), 7-hydroxy-2,8-dimethoxy-phenanthrene-1,4-dione (5), 7-hydroxy-2,10-dimethoxy-phenanthre-ne-1,4-dione (6), 7-dihydroxy-2-methoxy-9,10-dihydrophenanthrene-1,4-dione (7), 7-hydroxy-2-methoxy-phenanthrene-1,4-dione (8), 7-hydroxy-1-(p-hydroxybenzyl)-2,4-dimethoxy-9,10-dihydroxy-phenanthrene (9), 2,7-dihydroxy-1-(p-hydroxybenzyl)-4-methoxy-9,10-dihydroxy-phenanthrene (10). Compounds 5 and 6 were isolated from this plant for the first time. The isolated compounds were examined for their anti-hepatic fibrosis activity against HSC-T6 cells in vitro. The results showed that compounds 4 and 5 exhibited moderate growth inhibitory effects with IC50 61.9 μg/mL and 52.7 μg/mL, respectively.

Full Text Available This study presents a detailed analysis of two hitherto ignored or poorly understood paintings inspired by Cervantes’ Don Quijote de la Mancha: Dorothea (1823, by the New Yorker John Quidor, and Dance Scene (1656-1658, attributed to the Flemish Baroque master Joos van Craesbeeck. Dorothea is housed in the Brooklyn Museum of Art, and Dance Scene in Philadelphia’s The Rosenbach Museum and Gallery. The novelty of these two works is that Quidor’s is an ingenious and colourful improvement of a widely circulating black and white print, and van Craesbeeck’s miniature captures not only multiple don Quijotes and Sancho Panzas at a masquerade ball, but also the Dukes of Alba, for at the time the Duke was Governor General of the Spanish Netherlands.

Streams are important sources of carbon to the atmosphere, though knowing whether they merely outgas terrestrially derived carbon dioxide or mineralize terrestrial inputs of dissolved organic matter (DOM) is still a big challenge in ecology. The objective of this study was to investigate the influence of riparian groundwater (GW) and in-stream processes on the temporal pattern of stream DOM concentrations and quality in a forested headwater stream, and whether this influence differed between the leaf litter fall (LLF) period and the remaining part of the year (non-LLF). The spectroscopic indexes (fluorescence index, biological index, humification index, and parallel factor analysis components) indicated that DOM had an eminently protein-like character and was most likely originated from microbial sources and recent biological activity in both stream water and riparian GW. However, paired samples of stream water and riparian GW showed that dissolved organic carbon (DOC) and nitrogen (DON) concentrations as well as the spectroscopic character of DOM differed between the two compartments throughout the year. A simple mass balance approach indicated that in-stream processes along the reach contributed to reducing DOC and DON fluxes by 50 and 30 %, respectively. Further, in-stream DOC and DON uptakes were unrelated to each other, suggesting that these two compounds underwent different biogeochemical pathways. During the LLF period, stream DOC and DOC : DON ratios were higher than during the non-LLF period, and spectroscopic indexes suggested a major influence of terrestrial vegetation on stream DOM. Our study highlights that stream DOM is not merely a reflection of riparian GW entering the stream and that headwater streams have the capacity to internally produce, transform, and consume DOM.

Worldwide, barley is the main source of carbohydrate in the brewing process. However, corn is often used as an adjunct to improve and accelerate the fermentation process. Considering that, these two substrates are susceptible to fungal contamination as well as mycotoxins. The objective of the current study is to determine the incidence of the mycotoxins deoxynivalenol (DON) and fumonisin B 1 (FB 1 ) in industrial beers. The method applied for mycotoxin analyses included high performance liquid chromatography . The mean levels for recovery experiments were 89.6% for DON and 93.3% for FB 1 . DON was not detected in any of the analyzed samples whereas FB 1 was found in 49% of the 114 samples. The current survey demonstrated levels of FB 1 contamination in industrial beer, possibly due to the addition of contaminated adjuncts. It is necessary to establish maximum levels of mycotoxins in beer in Brazil and other countries in order to reduce health risks. Copyright © 2016 Elsevier Ltd. All rights reserved.

Un curioso coleccionista del siglo XVII: don Manuel de Porras

Full Text Available Art collecting - an avocation almost exclusive to royalty in Spain - has not had representatives among those who did not belong to the high nobility, not even among artists themselves. In many cases, the word "collection" has been applied to what in reality were mere lists of patrimonial properties. For all of the above, it is especially noteworthy to encounter someone who neither belonged to an elevated class nor was a painter, but who managed to unite, at great personal sacrifice, an important art collection. Manuel de Porras owned interesting and a relatively large number of paintings, sculptures and prints, some of them extremely valuable. As a good collector, in order to avoid the dispersion of these works, he donated them to the Shod Trinitarians in Madrid and the Oratory of Saint Philip Neri in Alcalá, but unfortunately, in spite of his good intentions, nothing has survived.

El coleccionismo —afición casi exclusiva de Reyes en España— no ha tenido representantes entre personas que no pertenecieran a la alta nobleza, ni entre los propios artistas. En muchos casos lo que se ha venido llamando colecciones son sólo relación de bienes patrimoniales.

Desgraciadamente, aunque lo donó —como buen coleccionista, para evitar su dispersión— a los Trinitarios calzados de Madrid y al Oratorio de San Felipe Neri de Alcalá, nada de ello ha llegado a nuestros días.

Full Text Available This essay focuses on the figure of D. Teotónio de Bragança, the Archbishop of Évora between 1578 and 1602, showing the importance of his building projects and artistic decorations, under the sign of Tridentine values. He adapted the principles of ‘restauro storico’ and the revitalization of ‘imagine sacrae’ in the Early Christian sanctuaries of his archdiocese. He promoted a new type of sacred architecture using artists formed in Rome, such as the architect and sculptor Pero Vaz Pereira. The art born in Évora in the late-16th century, under the sign of the Contra-Maniera, achieves a quality that rivals with that of the reign of King John III and the humanist André de Resende. Old cults and new iconographic themes emerge with D. Teotónio, such as SS. Manços, Jordão, Comba and other martyrs considered Évora-born. He ordered several works for Madrid, Rome and Florence to enrich the Cathedral and the Carthusian Monastery founded by him. Thus this period forms one of the most remarkable chapters in Portuguese Tridentine art and deserves to be properly analyzed.En este ensayo se aborda la figura de don Teotonio de Braganza (arzobispo de Évora entre 1578 y 1602 y su legado en los programas de decoración artística y en el modo como adaptó los principios tridentinos del restauro storico y la revitalización de las sacra imagines en lugares de culto paleocristiano de su archidiócesis.

The original brick is of low quality and its mineralogical paragenesis shows firing temperatures of 750-850º C. Its high water absorption capacity and porosity are responsible for its characteristic alteration and disgregation. Restoration brick is of better quality, fired at higher temperatures (~900º C. In relation to the original mortar, it is a lime one, with a relation close to 1:2; aggregates are plurimineral and an average grain size of 1,50 mm. Mortars from following restorations are different from the original ones, not in composition, practically the same with the exception of the most modern mortar which is cementbased, but in their dosification and in the aggregates grain size, as well as in the finishing of the joint. Repointing of the original brickwork, together with the presence of water (dampness, and the low quality of brick due to an insuficient and heterogeneous firing, are resposible of the deterioration the brick undergoes.

’Freud is finished, Einstein’s next’: Don DeLillo’s Cosmopolis, Chaos Theory, and Quantum Entanglement

Crystal Alberts

2016-05-01

Full Text Available This essay argues that, in 'Cosmopolis', DeLillo returns to mathematical topics and formal structures, like those presented in Ratner's Star, and expands them to reflect more recent developments in science and technology to contemplate time—the subject that permeates many of his twenty first century novels—and to highlight, variously, the unpredictable, uncertain, interconnected, and illusory nature of the contemporary world. Written in between the dot-com bubble burst and the aftermath of September 11, 2001, this essay asserts that 'Cosmopolis' is liminal: it offers a glimpse of the ruins of the future, and as one of its rejected titles suggests, it approaches an omega point. Drawing heavily on archival research in the 'Don DeLillo Papers' at University of Texas, Austin's Harry Ransom Center, this essay contends that 'Cosmopolis' is a thought experiment, of sorts, in which DeLillo incorporates his substantial and ongoing research on strange attractors, quantum entanglement, and the physics of time to consider the "[t]wo forces in this world, past and future." In doing so, this essay suggests that DeLillo calls for a reassessment of the time in which this text is set and proposes an alternate way of perceiving the post-9/11 world.

Dendroecological studies of rhododendron campanulatum d. don along the elevational gradient of manaslu conservation area, nepal himalaya

The increase in temperature due to global warming is affecting forest ecosystems worldwide. At the treeline ecotone growth is usually restricted by low temperatures. Recently, the impacts of climate change have been visible with the upward shift of the Himalaya fir (Abies spectabilis) in Nepal. Rhododendron campanulatum D. Don grows at the treeline ecotone and subalpine forest. Hardly any studies have been carried on this species in Nepal. The local people have reported that this species has been seen colonizing upper altitude in recent years, however, these needs to be verified with dendroecological studies. The study aims to assess the response of R. campanulatum to climatic variability and to evaluate the relationship of its basal diameter (Groundline) and age using dendroecological methods. Results reveal that the basal diameter was found to be significantly correlated with age (r2= 0.824, p<0.00001). Using the basal diameter age equations, attempts were made to study the age distribution along the altitudinal gradient. The species limit was observed at 4090 m asl. The age structure differed along the altitudinal gradient with multi age cohorts below the treeline and younger cohorts above the treeline. Results show that this species is migrating up at a rate of 24.7m per decade. (author)

Full Text Available The article deals with the language means of modality in the texts of military charters of the mid 18th cent. from the "Mikhailovsky stanitza hetman" archive (State Achieve of Volgograd Region. Military charters used to be major documents of legislation within Don Cossack Host, as being at that time an administrative unit in the territory of Russian Empire. The results of the contextual analysis verify the following facts: the charter texts are mainly characterized by an imperative tone of regulation that is caused by coordination between dominant meanings of a propositional (situational modality of necessity and pragmatic modality of volition, that are thought to be interrelated in utterances. The modal meaning of necessity is marked by the verbal construction with an independent infinitive or the combinations of modal verbs (imet' / possess; nadlezhat' / be to, modal predicatives with a dependent infinitive (dolzhen, nadobno, etc. / must (have to. Modality of volition is presented with a set of lexical units that possess the meanings of ordering, permission, offers, verbal forms that are used as performatives, or point to the status of a subject, etc. The texts under study represent some other modal meanings: possibility (with the words moch' / be able to; mozhno / could / may combined with an infinitive, in subordinate clauses with a particle li (if / wether, etc. in an interrogative clauses. In complex sentences with subordination combinations of various modal meanings are observed.

In this study, a total of nine different biotransformation products of the Fusarium mycotoxin deoxynivalenol (DON) formed in wheat during detoxification of the toxin are characterized by liquid chromatography—high resolution mass spectrometry (LC-HRMS). The detected metabolites suggest that DON is conjugated to endogenous metabolites via two major metabolism routes, namely 1) glucosylation (DON-3-glucoside, DON-di-hexoside, 15-acetyl-DON-3-glucoside, DON-malonylglucoside) and 2) glutathione conjugation (DON-S-glutathione, “DON-2H”-S-glutathione, DON-S-cysteinyl-glycine and DON-S-cysteine). Furthermore, conjugation of DON to a putative sugar alcohol (hexitol) was found. A molar mass balance for the cultivar ‘Remus’ treated with 1 mg DON revealed that under the test conditions approximately 15% of the added DON were transformed into DON-3-glucoside and another 19% were transformed to the remaining eight biotransformation products or irreversibly bound to the plant matrix. Additionally, metabolite abundance was monitored as a function of time for each DON derivative and was established for six DON treated wheat lines (1 mg/ear) differing in resistance quantitative trait loci (QTL) Fhb1 and/or Qfhs.ifa-5A. All cultivars carrying QTL Fhb1 showed similar metabolism kinetics: Formation of DON-Glc was faster, while DON-GSH production was less efficient compared to cultivars which lacked the resistance QTL Fhb1. Moreover, all wheat lines harboring Fhb1 showed significantly elevated D3G/DON abundance ratios. PMID:25775425

2016-09-01

We investigate dementia patients' use of "I don't know" (IDK) in Mini-Mental State Exams (MMSEs) using objective linguistic indicators to differentiate IDK signalling lack of knowledge (LOK) from IDK used to hedge responses, affect exam progression etc. We hypothesize that increased proportional use of LOK-IDK correlates with worsening dementia severity. 189 IDK tokens were extracted from 72 MMSE interactions and coded for linguistic/social characteristics. A data-driven, discourse position/relation-based functional taxonomy for IDK in MMSE was developed and the resulting functional distribution was subjected to multiple logistic regression. Use of LOK-IDK (vs. non-LOK-IDK) is significantly correlated (p=0.01) with clinicians' subjective ratings of patients' dementia as 'severe' vs. 'mild'/'moderate', indicating that objective sociolinguistic criteria approximate physician judgments. 92% of 'severe' patients' IDKs signalled LOK, compared to only 68% of 'mild' patients', suggesting that uncritical interpretation of IDK as signalling LOK would result in 8-32% of IDK responses being mis-scored. LOK and non-LOK uses distinguished on the basis of reliable, objective usage patterns are differentially distributed among dementia severity groups. LOK-IDK serves as a supplemental indicator of dementia severity. Correct interpretation may improve diagnostic accuracy and allow clinicians to respond supportively during cognitive assessment.

Full Text Available Deoxynivalenol (DON, the mycotoxin produced mainly by Fusarium graminearum and found in contaminated cereal-based foodstuff, has been consistently detected in body fluids in adults. Available data in children and adolescents are scarce. This study assessed urinary DON concentrations in children aged 3–9 years (n = 40 and adolescents aged 10–17 years (n = 39 in the UK. Morning urine samples were collected over two consecutive days and analysed for free DON (un-metabolised form, DON-glucuronides (DON-GlcA, deepoxy deoxynivalenol (DOM-1, and total DON (sum of free DON, DON-GlcA, and DOM-1. Total DON was detected in the urine of >95% of children and adolescents on both days. Mean total DON concentrations (ng/mg creatinine were 41.6 and 21.0 for children and adolescents, respectively. The greatest total DON levels were obtained in female children on both days (214 and 219 ng/mg creatinine on days 1 and 2, respectively. Free DON and DON-GlcA were detected in most urine specimens, whereas DOM-1 was not present in any sample. Estimation of dietary DON exposure suggested that 33–63% of children and 5–46% of adolescents exceeded current guidance regarding the maximum provisional tolerable daily intake (PMTDI for DON. Although moderate mean urinary DON concentrations were shown, the high detection frequency of urinary DON, the maximum biomarker concentrations, and estimated dietary DON exposure are concerning.

Sources of error in etched-track radon measurements and a review of passive detectors using results from a series of radon intercomparisons

Etched-track passive radon detectors are a well established and apparently simple technology. As with any measurement system, there are multiple sources of uncertainty and potential for error. The authors discuss these as well as good quality assurance practices. Identification and assessment of sources of error is crucial to maintain high quality standards by a measurement laboratory. These sources can be found both within and outside the radon measurement laboratory itself. They can lead to changes in track characteristics and ultimately detector response to radon exposure. Changes don't just happen during etching, but can happen during the recording or counting of etched-tracks (for example ageing and fading effects on track sensitivity, or focus and image acquisition variables). Track overlap means the linearity of response of detectors will vary as exposure increases. The laboratory needs to correct the calibration curve due to this effect if it wishes to offer detectors that cover a range of exposures likely to be observed in the field. Extrapolation of results to estimate annual average concentrations also has uncertainty associated with it. Measurement systems need to be robust, reliable and stable. If a laboratory is not actively and constantly monitoring for anomalies via internal testing, the laboratory may not become aware of a problem until some form of external testing occurs, eg an accreditation process, performance test, interlaboratory comparison exercise or when a customer has cause to query results. Benchmark standards of accuracy and precision achievable with passive detectors are discussed drawing on trends from the series of intercomparison exercises for passive radon detectors which began in 1982, organised by the National Radiological Protection Board (NRPB), subsequently the Health Protection Agency (HPA).

Full Text Available RESUMEN: D. Lorenzo Galíndez de Carvajal fue un personaje destacado en la Corte de los Reyes Católicos y Carlos V, además de cronista real. Sin embargo, para alcanzar esta posición tuvo que manipular sus orígenes familiares, siendo como era hijo de un arcediano de Coria y de una moza de servicio en una posada. Las manipulaciones de don Lorenzo tuvieron el éxito apetecido, sin embargo, treinta años después de su muerte, las informaciones realizadas sobre un nieto suyo que quería ingresar en el Colegio Mayor de Oviedo, en Salamanca, sacaron a la luz toda la estrategia familiar que tuvo que poner en marcha su ilustre abuelo para alcanzar la posición a la que llegó.ABSTRACT: D. Lorenzo Galíndez de Carvajal was one of the most influential courtiers at the Catholic King's court. He, too, was one of their chroniclers, but he had to forge his familiar origins in order to hold his job. He was an illegitimate son; his father was an archdeacon in Coria and his mother a maidservant. D. Lorenzo Galíndez de Carvajal succeeded in hiding his origins and his descendants became related to nobility by marriage. Howeyer all his grandfather's impostures and the ways followed by aristocracy to manipulate its origins were discovered when one of his grandsons tried to be admitted to the Oviedo College about the middle of the XVIth century.

Biotransformation of mycotoxins in animals comprises phase I and phase II metabolisation reactions. For the trichothecene deoxynivalenol (DON), several phase II biotransformation reactions have been described resulting in DON-glutathiones, DON-glucuronides and DON-sulfates made by glutathione-S-transferases, uridine-diphosphoglucuronyl transferases and sulfotransferases, respectively. These metabolites can be easily excreted and are less toxic than their free compounds. Here, we demonstrate for the first time in the animal kingdom the conversion of DON to DON-3-glucoside (DON-3G) via a model system with plant pathogenic aphids. This phase II biotransformation mechanism has only been reported in plants. As the DON-3G metabolite was less toxic for aphids than DON, this conversion is considered a detoxification reaction. Remarkably, English grain aphids (Sitobion avenae) which co-occur with the DON producer Fusarium graminearum on wheat during the development of fusarium symptoms, tolerate DON much better and convert DON to DON-3G more efficiently than pea aphids (Acyrthosiphon pisum), the latter being known to feed on legumes which are no host for F. graminearum. Using a non-targeted high resolution mass spectrometric approach, we detected DON-diglucosides in aphids probably as a result of sequential glucosylation reactions. Data are discussed in the light of an eventual co-evolutionary adaptation of S. avenae to DON.

Chandra Source Catalog (CSC) master source pipeline processing seeks to automatically detect sources and compute their properties. Since Chandra is a pointed mission and not a sky survey, different sky regions are observed for a different number of times at varying orientations, resolutions, and other heterogeneous conditions. While this provides an opportunity to collect data from a potentially large number of observing passes, it also creates challenges in determining the best way to combine different detection results for the most accurate characterization of the detected sources. The CSC master source pipeline correlates data from multiple observations by updating existing cataloged source information with new data from the same sky region as they become available. This process sometimes leads to relatively straightforward conclusions, such as when single sources from two observations are similar in size and position. Other observation results require more logic to combine, such as one observation finding a single, large source and another identifying multiple, smaller sources at the same position. We present examples of different overlapping source detections processed in the current version of the CSC master source pipeline. We explain how they are resolved into entries in the master source database, and examine the challenges of computing source properties for the same source detected multiple times. Future enhancements are also discussed. This work is supported by NASA contract NAS8-03060 (CXC).

Polyflavonoids from Pinus radiata (D. Don.) are an abundant natural oligomers highly desirable as renewable chemicals. However, structural modification of polyflavonoids is a viable strategy in order to use such polyphenols as macrobuilding-blocks for biomaterial design. Polyflavonoids were esterified with three five-member cyclic anhydrides (maleic, itaconic, and citraconic) at 20 °C during 24 h in order to diversify physicochemical-, and biological-properties for agricultural, and food-packaging applications. In addition, the influence of the chemical modification, as well as the chemical structure of the grafting on toxicological features was evaluated. Structural features of derivatives were analyzed by spectroscopy (FT-IR and 1 H-NMR), and the degree of substitution was calculated. Toxicological profile was assessed by using three target species in a wide range of concentration (0.01-100 mgL - 1 ). Effect of polyflavonoids on the growth rate (Selenastrum capricornutum), mortality (Daphnia magna), and germination and radicle length (Lactuca sativa) was determined. Chemical modification affects the toxicological profile on the derivatives in a high extent. Results described remarkable differences in function of the target specie. The bioassays indicate differences of the polyflavonoids toxicological profile associated to the chemical structure of the grafting. Results allowed conclude that polyflavonoids from pine bark show slight toxic properties. Copyright © 2017 Elsevier Ltd. All rights reserved.

The quantitative real-time polymerase chain reaction (qRT-PCR) approach has become a widely used method to analyze expression patterns of target genes. The selection of an optimal reference gene is a prerequisite for the accurate normalization of gene expression in qRT-PCR. The present study constitutes the first systematic evaluation of potential reference genes in Rhododendron molle G. Don. Eleven candidate reference genes in different tissues and flowers at different developmental stages of R. molle were assessed using the following three software packages: GeNorm, NormFinder, and BestKeeper. The results showed that EF1- α (elongation factor 1-alpha), 18S (18s ribosomal RNA), and RPL3 (ribosomal protein L3) were the most stable reference genes in developing rhododendron flowers and, thus, in all of the tested samples, while tublin ( TUB ) was the least stable. ACT5 (actin), RPL3 , 18S , and EF1- α were found to be the top four choices for different tissues, whereas TUB was not found to favor qRT-PCR normalization in these tissues. Three stable reference genes are recommended for the normalization of qRT-PCR data in R. molle . Furthermore, the expression profiles of RmPSY (phytoene synthase) and RmPDS (phytoene dehydrogenase) were assessed using EF1- α, 18S , ACT5 , RPL3 , and their combination as internals. Similar trends were found, but these trends varied when the least stable reference gene TUB was used. The results further prove that it is necessary to validate the stability of reference genes prior to their use for normalization under different experimental conditions. This study provides useful information for reliable qRT-PCR data normalization in gene studies of R. molle .

1986-01-01

With the availability of antibody against deoxynivalenol triacetate (DON-triacetate), a radioimmunoassay (RIA) for DON in wheat was developed. DON is extracted from the sample with acetonitrile-water defatted with hexane, and then reacted with acetic anhydride to form DON-triacetate. The reaction mixture is loaded onto a C-18 cartridge to remove excess reagents and impurities. Acetylated DON is eluted from the cartridge with 50% methanol in water, and then analyzed by radioimmunoassay utilizing antiserum against DON-triacetate and tritiated DON-triacetate. Overall recovery for DON added to wheat between 50 and 5000 ppb was 86% with a standard deviation of 7% and coefficient of variation of 8%. The limit of detection for DON was about 20 ppb. Analysis of 12 naturally contaminated wheat, corn, and mixed feed samples for DON revealed that RIA results agreed well with thin layer chromatographic analyses performed by other laboratories

Source-space ICA for MEG source imaging.

Jonmohamadi, Yaqub; Jones, Richard D

2016-02-01

One of the most widely used approaches in electroencephalography/magnetoencephalography (MEG) source imaging is application of an inverse technique (such as dipole modelling or sLORETA) on the component extracted by independent component analysis (ICA) (sensor-space ICA + inverse technique). The advantage of this approach over an inverse technique alone is that it can identify and localize multiple concurrent sources. Among inverse techniques, the minimum-variance beamformers offer a high spatial resolution. However, in order to have both high spatial resolution of beamformer and be able to take on multiple concurrent sources, sensor-space ICA + beamformer is not an ideal combination. We propose source-space ICA for MEG as a powerful alternative approach which can provide the high spatial resolution of the beamformer and handle multiple concurrent sources. The concept of source-space ICA for MEG is to apply the beamformer first and then singular value decomposition + ICA. In this paper we have compared source-space ICA with sensor-space ICA both in simulation and real MEG. The simulations included two challenging scenarios of correlated/concurrent cluster sources. Source-space ICA provided superior performance in spatial reconstruction of source maps, even though both techniques performed equally from a temporal perspective. Real MEG from two healthy subjects with visual stimuli were also used to compare performance of sensor-space ICA and source-space ICA. We have also proposed a new variant of minimum-variance beamformer called weight-normalized linearly-constrained minimum-variance with orthonormal lead-field. As sensor-space ICA-based source reconstruction is popular in EEG and MEG imaging, and given that source-space ICA has superior spatial performance, it is expected that source-space ICA will supersede its predecessor in many applications.

Recently, deoxynivalenol-3-sulfate (DON-3-sulfate) was proposed as a major DON metabolite in poultry. In the present work, the first LC-MS/MS based method for determination of DON-3-sulfate, deepoxy-DON-3-sulfate (DOM-3-sulfate), DON, DOM, DON sulfonates 1, 2, 3, and DOM sulfonate 2 in excreta samples of chickens and turkeys was developed and validated. To this end, DOM-3-sulfate was chemically synthesized and characterized by NMR and LC-HR-MS/MS measurements. Application of the method to excreta and chyme samples of four feeding trials with turkeys, chickens, pullets, and roosters confirmed DON-3-sulfate as the major DON metabolite in all poultry species studied. Analogously to DON-3-sulfate, DOM-3-sulfate was formed after oral administration of DOM both in turkeys and in chickens. In addition, pullets and roosters metabolized DON into DOM-3-sulfate. In vitro transcription/translation assays revealed DOM-3-sulfate to be 2000 times less toxic on the ribosome than DON. Biological recoveries of DON and DOM orally administered to broiler chickens, turkeys, and pullets were 74%-106% (chickens), 51%-72% (roosters), and 131%-151% (pullets). In pullets, DON-3-sulfate concentrations increased from jejunum chyme samples to excreta samples by a factor of 60. This result, put into context with earlier studies, indicates fast and efficient absorption of DON between crop and jejunum, conversion to DON-3-sulfate in intestinal mucosa, liver, and possibly kidney, and rapid elimination into excreta via bile and urine.

Deoxynivalenol (DON), the most commonly occurring trichothecene in nature, may affect animal and human health through causing diarrhea, vomiting, gastrointestinal inflammation, and immunomodulation. DON-3-glucoside (DON-3G) as a major plant metabolite of the mycotoxin is another "emerging" food safety issue in recent years. Humans may experience potential health risks by consuming DON-contaminated food products. Thus, it is crucial for human and animal health to study also the degradation of DON and DON-3G during thermal food processing. Baking, boiling, steaming, frying, and extrusion cooking are commonly used during thermal food processing and have promising effects on the reduction of mycotoxins in food. For DON, however, the observed effects of these methods, as reported in numerous studies, are ambiguous and do not present a clear picture with regard to reduction or transformation. This review summarized the influence of thermal processing on the stability of DON and the formation of degradation/conversion products. Besides this, also a release of DON and DON-3G from food matrix as well as the release of DON from DON-3G during processing is discussed. In addition, some conflicting findings as reported from the studies on thermal processing as well as cause-effect relationships of the different thermal procedures are explored. Finally, the potential toxic profiles of DON degradation products are discussed as well when data are available.

Full Text Available The aim of this paper is to analyse the linguistic factors constraining the use of personal clitics lo(s, la(s, le(s in XVth Century Middle-Age Castilian, as revealed in the Relación de los Hechos de Don Miguel Lucas de Iranzo (1458. A multivariate analysis of data from this text shows that internal (morphological, syntactic, lexical and textual factors interact and allows us to imagine the simplest and original context where leísmo could start. A nearly categorical tendency to employ le for male referents as direct objects is developed with human antecedents and where Latin used dative case or alternated between dative and accusative case. If Latin used accusative case, occurrence of le (leísmo depends on a set of linguistic constraints whose effect is systematic and predictable, as shows a logistic regression analysis carried out in this paper. Use of le (leísmo for human antecedents is constrained by the following internal factors: etymology, the number and the clitic's position within the sentence, type of syntactic structure and the verb's tense.

Full Text Available Post-translational modifications of chromatin structure by histone acetyltransferase (HATs play a central role in the regulation of gene expression and various biological processes in eukaryotes. Although HAT genes have been studied in many fungi, few of them have been functionally characterized. In this study, we identified and characterized four putative HATs (FgGCN5, FgRTT109, FgSAS2, FgSAS3 in the plant pathogenic ascomycete Fusarium graminearum, the causal agent of Fusarium head blight of wheat and barley. We replaced the genes and all mutant strains showed reduced growth of F. graminearum. The ΔFgSAS3 and ΔFgGCN5 mutant increased sensitivity to oxidative and osmotic stresses. Additionally, ΔFgSAS3 showed reduced conidia sporulation and perithecium formation. Mutant ΔFgGCN5 was unable to generate any conidia and lost its ability to form perithecia. Our data showed also that FgSAS3 and FgGCN5 are pathogenicity factors required for infecting wheat heads as well as tomato fruits. Importantly, almost no Deoxynivalenol (DON was produced either in ΔFgSAS3 or ΔFgGCN5 mutants, which was consistent with a significant downregulation of TRI genes expression. Furthermore, we discovered for the first time that FgSAS3 is indispensable for the acetylation of histone site H3K4, while FgGCN5 is essential for the acetylation of H3K9, H3K18, and H3K27. H3K14 can be completely acetylated when FgSAS3 and FgGCN5 were both present. The RNA-seq analyses of the two mutant strains provide insight into their functions in development and metabolism. Results from this study clarify the functional divergence of HATs in F. graminearum, and may provide novel targeted strategies to control secondary metabolite expression and infections of F. graminearum.

This paper discusses the sources of radiation in the narrow perspective of radioactivity and the even narrow perspective of those sources that concern environmental management and restoration activities at DOE facilities, as well as a few related sources. Sources of irritation, Sources of inflammatory jingoism, and Sources of information. First, the sources of irritation fall into three categories: No reliable scientific ombudsman to speak without bias and prejudice for the public good, Technical jargon with unclear definitions exists within the radioactive nomenclature, and Scientific community keeps a low-profile with regard to public information. The next area of personal concern are the sources of inflammation. This include such things as: Plutonium being described as the most dangerous substance known to man, The amount of plutonium required to make a bomb, Talk of transuranic waste containing plutonium and its health affects, TMI-2 and Chernobyl being described as Siamese twins, Inadequate information on low-level disposal sites and current regulatory requirements under 10 CFR 61, Enhanced engineered waste disposal not being presented to the public accurately. Numerous sources of disinformation regarding low level radiation high-level radiation, Elusive nature of the scientific community, The Federal and State Health Agencies resources to address comparative risk, and Regulatory agencies speaking out without the support of the scientific community

Mineral analysis of seven Pinus species grown in different regions of New Zealand; Armand pine ( Pinus armandii Franch), Swiss stone pine ( Pinus cembra L.), Mexican pinyon ( Pinus cembroides Zucc. var. bicolor Little), Coulter pine ( Pinus coulteri D. Don), Johann's pine ( Pinus johannis M.F. Robert), Italian stone pine ( Pinus pinea L.) and Torrey pine ( Pinus torreyana Parry ex Carrière), was carried out using an inductively coupled plasma optical emission spectrophotometer (ICP-OES) analysis. Fourteen different minerals (Al, B, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, S and Zn) were identified in all seven varieties, except that no Al or Na was found in Pinus coulteri D. Don. New Zealand grown pine nuts are a good source of Cu, Mg, Mn, P and Zn, meeting or exceeding the recommended RDI for these minerals (based on an intake of 50 g nuts/day) while they supplied between 39%-89% of the New Zealand RDI for Fe. Compared to other commonly eaten tree-nuts New Zealand grown pine nuts are an excellent source of essential minerals.

Full Text Available Purpose: The late Don R. Swanson was well appreciated during his lifetime as Dean of the Graduate Library School at University of Chicago, as winner of the American Society for Information Science Award of Merit for 2000, and as author of many seminal articles. In this informal essay, I will give my personal perspective on Don’s contributions to science, and outline some current and future directions in literature-based discovery that are rooted in concepts that he developed. Design/methodology/approach: Personal recollections and literature review. Findings: The Swanson A-B-C model of literature-based discovery has been successfully used by laboratory investigators analyzing their findings and hypotheses. It continues to be a fertile area of research in a wide range of application areas including text mining, drug repurposing, studies of scientific innovation, knowledge discovery in databases, and bioinformatics. Recently, additional modes of discovery that do not follow the A-B-C model have also been proposed and explored (e.g. so-called storytelling, gaps, analogies, link prediction, negative consensus, outliers, and revival of neglected or discarded research questions. Research limitations: This paper reflects the opinions of the author and is not a comprehensive nor technically based review of literature-based discovery. Practical implications: The general scientific public is still not aware of the availability of tools for literature-based discovery. Our Arrowsmith project site maintains a suite of discovery tools that are free and open to the public (http://arrowsmith.psych.uic.edu, as does BITOLA which is maintained by Dmitar Hristovski (http:// http://ibmi.mf.uni-lj.si/bitola, and Epiphanet which is maintained by Trevor Cohen (http://epiphanet.uth.tmc.edu/. Bringing user-friendly tools to the public should be a high priority, since even more than advancing basic research in informatics, it is vital that we ensure that scientists

Effects of Milling and Cooking Processes on the Deoxynivalenol Content in Wheat

Full Text Available Deoxynivalenol (DON, vomitoxin is a natural-occuring mycotoxin mainly produced by Fusarium graminearum, a food-borne fungi widely distributed in crops and it is one of the most important mycotoxins in wheat and wheat-based foods and feeds. DON affects animal and human health causing diarrhea, vomiting, gastro-intestinal inflammation, and immunomodulation. Since the rate of the occurrence of DON in wheat is high, effective procedures to remove or eliminate DON from food products is essential to minimize exposures in those who consume large amounts of wheat. Cleaning prior to milling reduced to some extent the concentration of DON in final products. Since DON is distributed throughout the kernels, with higher content in the outer skin, milling is also effective in reducing the DON levels of wheat-based foods if bran and shorts are removed before thermal cooking. DON is water-soluble and cooking with larger amounts of water lowers DON content in products such as spaghetti and noodles. During baking or heating, DON is partially degraded to DON-related chemicals, whose toxicological effects are not studied well. This paper reviews the researches on the effects of milling and cooking on the DON level and discusses the perspectives of further studies.

Full Text Available In the present article the question of the folklore phenomenon in the folk art of the Lower Volga Region in the first third of the 20th century is considered. In the course of research high emphasis was placed on the Cossack subject matter. The role of B.S. Laschilin and A.M. Listopadov in collecting and publishing folk art, the folklore of the Don Cossacks, is revealed. Boris Stepanovitch Laschilin’s work left a great impact in the artistic life of our region. In B.S. Laschilin’s books, that were published in Rostov-on-Don, Saratov, Stalingrad-Volgograd, contained tales, fairy tales, bylinas, legends, songs, ditties, proverbs, sayings, ancient dramas of the first Russian folk theatres, exorcisms. Boris Stepanovitch kept selecting songs and ditties, chastooshkas for Voronezh Folk Choir “Voronezh girls”, which are still in the repertoire of the Pyatnitsky Russian Folk Chorus. Folklorist and musician Alexander Mikhailovich Listopadov, who collected and studied folk songs from his youth up, and recorded them in the Don Region hamlets and Cossack villages, spent more than 50 years of his life on the research of the Don Cossack’s musical culture. Alexander Mikhailovich Listopadov’s heritage made an important contribution to the native musical folklore study. Folklore compositions is a unique source of knowledge of history, way of life, moral and other national concepts, which allows us to reconstitute a linguistic personality of a definite historical epoch.

The Chandra Source Catalog (CSC) contains fields of view that have been studied with individual, uninterrupted observations that span integration times ranging from 1 ksec to 160 ksec, and a large number of which have received (multiple) repeat observations days to years later. The CSC thus offers an unprecedented look at the variability of the X-ray sky over a broad range of time scales, and across a wide diversity of variable X-ray sources: stars in the local galactic neighborhood, galactic and extragalactic X-ray binaries, Active Galactic Nuclei, etc. Here we describe the methods used to identify and quantify source variability within a single observation, and the methods used to assess the variability of a source when detected in multiple, individual observations. Three tests are used to detect source variability within a single observation: the Kolmogorov-Smirnov test and its variant, the Kuiper test, and a Bayesian approach originally suggested by Gregory and Loredo. The latter test not only provides an indicator of variability, but is also used to create a best estimate of the variable lightcurve shape. We assess the performance of these tests via simulation of statistically stationary, variable processes with arbitrary input power spectral densities (here we concentrate on results of red noise simulations) at variety of mean count rates and fractional root mean square variabilities relevant to CSC sources. We also assess the false positive rate via simulations of constant sources whose sole source of fluctuation is Poisson noise. We compare these simulations to an assessment of the variability found in real CSC sources, and estimate the variability sensitivities of the CSC.

Probabilistic Inference of Nuclear Power plant Transients (SPRINT), the SPRINT tool takes, as input, observations and trends in key instrument readings from the Nuclear Power Plant (NPP). lt uses these observations to interrogate a database of precalculated source terms, typically compiled from existing NPP analyses performed as Part of a Level 2 PSA study. The basis for this interrogation is a probabilistic logic model, or belief network, of plant behaviour developed by plant experts (using, as a platform, the Netica Bayesian network Software). This is included in the application as a data file. The end points of this logic model are then mapped onto the database of pre-calculated source terms. This process is very rapid (taking only as long as is required to input the responses to a series of questions about the NPP status) and can overcome 'don't know' responses in the question set by resorting to prior probabilities determined by the plant experts who set up the model. The SPRINT application is the combination of the main SPRINT interface containing the user input/output screens and the logic model (dne file) loaded in the Netica application. The conditional probability tables. Beside the network structure itself, the key data in the model are the conditional probabilities that define the strength of influence of a parent node an a daughter node. These values are stored in the model file as network tables, one table per, node, called Conditional Probability Tables (CPTs). However, as detailed documentation of the CPT values is vital during development of reactor specific models, the Net2SS pro.gram was written to take any dne file and output the CPT data as an Excel spreadsheet which can be modified, annotated and loaded back into the dne file via the SPRINT interface. The repository file. The parameters defining the source term data stored in the Excel repository file is determined by the requirement that SPRINT be capable of generating input files for Decision Support

Characterization of a source of carbon particles produced by laser ablation and used for the calibration of erosion measurement made by spectroscopy in a tokamak

In a tokamak, plasma-wall interactions lead to the erosion of plasma facing components, which can be detrimental to plasma operation and to the safety of the tokamak. In order to fulfill the safety requirements imposed to the ITER project, it is necessary to monitor the amount of eroded material. Optical emission spectroscopy in the visible range is traditionally used to measure particle fluxes from the wall to the plasma. These measurements are done thanks to a collisional radiative model based on atomic physics data. However, these data don't take into account the observation geometry of the spectroscopic diagnostic, and suffer from relatively large uncertainties. Furthermore, transport, deposition and re-erosion phenomena, as well as the evolution of the transmission or the reflection of optical components can lead to an incorrect estimation of the amount of effectively eroded material. An in situ calibration technique, which consists in injecting by laser a known carbon particle source in the line of sight of the spectroscopic diagnostic during plasma operation, is proposed. The experimental study of laser ablation of carbon allowed to determine the optimal conditions for the constitution of this source, and to characterise the ablated species. These experiments are completed by a modelling of the emission spectrum of the laser induced plasma, in order to obtain information on its ionisation degree. Finally, results of the first validation experiments realised in the German TEXTOR tokamak are presented and discussed. (author)

Atmospheric deposition of total dissolved nitrogen (TDN) is an important source of nitrogen for ocean primary productivity that has increased since the industrial revolution. Thus, understanding its role in the ocean nitrogen cycle will help assess recent changes in ocean biogeochemistry. In the anoxic Cariaco basin, the place of the CARIACO Ocean Time-Series Program, the influence of atmospherically-deposited TDN on marine biogeochemistry is unknown. In this study, we measured atmospheric TDN concentrations as dissolved organic (DON) and inorganic (DIN) nitrogen (TDN = DIN + DON) in atmospheric suspended particles and wet deposition samples at the northeast of the basin during periods of the wet (August-September 2008) and dry (March-April 2009) seasons. We evaluated the potential anthropogenic N influences by measuring wind velocity and direction, size-fractionated suspended particles, chemical traces and by performing back trajectories. We found DIN and DON concentration values that ranged between 0.11 and 0.58 μg-N m-3 and 0.11-0.56 μg-N m-3 in total suspended particles samples and between 0.08 and 0.54 mg-N l-1 and 0.02-1.3 mg-N l-1 in wet deposition samples, respectively. Continental air masses increased DON and DIN concentrations in atmospheric suspended particles during the wet season. We estimate an annual TDN atmospheric deposition (wet + particles) of 3.6 × 103 ton-N year-1 and concluded that: 1) Atmospheric supply of TDN plays a key role in the C and N budget of the basin because replaces a fraction of the C (20% by induced primary production) and N (40%) removed by sediment burial, 2) present anthropogenic N could contribute to 30% of TDN atmospheric deposition in the basin, and 3) reduced DON (gas + particles) should be a significant component of bulk N deposition.

A total of 50 samples of poultry feed mixtures of Slovakian origin were analyzed for eight toxicologically significant Fusarium mycotoxins, namely zearalenone (ZON), A-trichothecenes: diacetoxyscirpenol (DAS), T-2 toxin (T-2) and HT-2 toxin (HT-2) and B-trichothecenes: deoxynivalenol (DON), 3-acetyl-deoxynivalenol (3-ADON), 15-acetyl-deoxynivalenol (15-ADON) and nivalenol (NIV). The A-trichothecenes and the B-trichothecenes were detected by means of high pressure liquid chromatography with tandem mass spectrometry detection (HPLC-MS/MS) and gas chromatography electron capture detection (GC-ECD), respectively. Reversed phase-high performance liquid chromatography with a fluorescence detector (RP-HPLC-FLD) was used for ZON detection. The most frequent mycotoxin detected was T-2, which was found in 45 samples (90%) in relatively low concentrations ranging from 1 to 130 microg kg(-1) (average 13 microg kg(-1)), followed by ZON that was found in 44 samples (88%) in concentrations ranging from 3 to 86 microg kg(-1) (average 21 microg kg(-1)). HT-2 and DON were detected in 38 (76%) and 28 (56%) samples, respectively, in concentrations of 2 to 173 (average 18 microg kg(-1)) for HT-2 and 64 to 1230 microg kg(-1) sample (average 303 microg kg(-1)) for DON. The acetyl-derivatives of DON were in just four samples, while NIV was not detected in any of the samples investigated. In as many as 22 samples (44%), a combination of four simultaneously co-occurring mycotoxins, i.e. T-2, HT-2, ZON and DON, was revealed. Despite the limited number of samples investigated during this study poultry feed mixtures may represent a risk from a toxicological point of view and should be regarded as a potential source of the Fusarium mycotoxins in Central Europe. This is the first reported study dealing with zearalenone and trichothecene contamination of poultry mixed feeds from Slovakia.
