Eros in the first century’s Christian theology. Pseudo-Dionysius the Areopagite

Directory of Open Access Journals (Sweden)

Mircea Adrian Marica

2015-11-01

Full Text Available For among most contemporaries, the concept of Eros seems to have nothing to do with Christianity. Sifting through the psychoanalysis of sexual fantasy, theologically it says nothing. Our study gives reasons showing that for theologians since the dawn of the Christian era, Eros-love plays a fundamental role.. The connotations of this concept, however, are different from those of today, when its sensory meaning is more restricted to sexuality. Greek theologians of the first centuries after Christ, taught the concept of Plato enshrined as a unifying enthusiasm, the attraction of inferior to superior states, as “hungry and thirsty” for something continuously higher, developing, and enriching the connotation. The work of Dionysius ((Pseudo Areopagite, the Idea of Good, leads us step by step up the ascent of the erotically chaste, and is identified with the One-God, who is the very source of love. Consequently, Eros-love originates from God, Eros- love being not only an ascending but firstly a descending love, which calls for a reciprocal communion.

Endoplasmic reticulum transport of glutathione by Sec61 is regulated by Ero1 and Bip

In the endoplasmic reticulum (ER), Ero1 catalyzes disulfide bond formation and promotes glutathione (GSH) oxidation to GSSG. Since GSSG cannot be reduced in the ER, maintenance of the ER glutathione redox state and levels likely depends on ER glutathione import and GSSG export. We used quantitative...... oxidation through Ero1 reductive activation, which inhibits glutathione import in a negative regulatory loop. During ER stress, transport is activated by UPR-dependent Ero1 induction, and cytosolic glutathione levels increase. Thus, the ER redox poise is tuned by reciprocal control of glutathione import...... by reduction, causing Bip oxidation and inhibition of glutathione transport. Coupling of glutathione ER import to Ero1 activation provides a basis for glutathione ER redox poise maintenance....

In the early secretory compartment (ESC), a network of chaperones and enzymes assists oxidative folding of nascent proteins. Ero1 flavoproteins oxidize protein disulfide isomerase (PDI), generating H2O2 as a byproduct. Peroxiredoxin 4 (Prx4) can utilize luminal H2O2 to oxidize PDI, thus favoring oxidative folding while limiting oxidative stress. Interestingly, neither ER oxidase contains known ER retention signal(s), raising the question of how cells prevent their secretion. Here we show that the two proteins share similar intracellular localization mechanisms. Their secretion is prevented by sequential interactions with PDI and ERp44, two resident proteins of the ESC-bearing KDEL-like motifs. PDI binds preferentially Ero1α, whereas ERp44 equally retains Ero1α and Prx4. The different binding properties of Ero1α and Prx4 increase the robustness of ER redox homeostasis. PMID:23979138

Full Text Available This paper analyzes the graphic design of the international art journal “Vešč’-Gegenstand-Objet”, published in Berlin in 1922 by the Russian architect, painter, photographer and designer Lazar’ Markovič Lisickij (1890-1941, better known as El’ Lisickij, together with the Russian writer Il’ja Grigor’evič Èrenburg (1891-1967.Although it lasted only three issues (issues one and two were combined in a single volume which appeared in March/April 1922, while the last number appeared in May 1922, “Vešč’” had a strong influence on contemporary art. It was published in German, French and Russian and was meant both as a bridge between Russia and Europe after the years of war and revolution and as a symbol of the beginning of a new creative era. Mainly focusing on new Suprematist and Constructivist works, the journal included essays on several fields of art such as literature, cinema, theatre, painting, sculpture, architecture and music.In this paper I focus on the innovative graphic design of the two volumes of “Vešč’” entirely realized by El’ Lisickij. Referring to his own theories about book design, Lisickij created a functional and innovative layout and a striking cover, challenging the traditional graphic design practice by using exclusively standard typographic elements such as punctuation marks, typographic lines, geometric forms and typesetting.

Energy Return on Energy Invested (ERoEI) for photovoltaic solar systems in regions of moderate insolation

International Nuclear Information System (INIS)

Ferroni, Ferruccio; Hopkirk, Robert J.

2016-01-01

Many people believe renewable energy sources to be capable of substituting fossil or nuclear energy. However there exist very few scientifically sound studies, which apply due diligence to substantiating this impression. In the present paper, the case of photovoltaic power sources in regions of moderate insolation is analysed critically by using the concept of Energy Return on Energy Invested (ERoEI, also called EROI). But the methodology for calculating the ERoEI differs greatly from author-to-author. The main differences between solar PV Systems are between the current ERoEI and what is called the extended ERoEI (ERoEI EXT ). The current methodology recommended by the International Energy Agency is not strictly applicable for comparing photovoltaic (PV) power generation with other systems. The main reasons are due to the fact that on one hand, solar electricity is very material-intensive, labour-intensive and capital-intensive and on the other hand the solar radiation exhibits a rather low power density. - Highlights: •Data are available from several years of photovoltaic energy experience in northern Europe. •These are used to show the way to calculate a full, extended ERoEI. •The viability and sustainability in these latitudes of photovoltaic energy is questioned. •Use of photovoltaic technology is shown to result in creation of an energy sink.

2012-01-01

Full Text Available RANK („Receptor Activator of NF-κB“ und sein Ligand RANKL sind Schlüsselmoleküle im Knochenmetabolismus und spielen eine essenzielle Rolle in der Entstehung von pathologischen Knochenveränderungen. Die Deregulation des RANK/RANKL-Systems ist zum Beispiel ein Hauptgrund für das Auftreten von postmenopausaler Osteoporose bei Frauen. Eine weitere wesentliche Funktion von RANK und RANKL liegt in der Entwicklung von milchsekretierenden Drüsen während der Schwangerschaft. Dabei regulieren Sexualhormone, wie zum Beispiel Progesteron, die Expression von RANKL und induzieren dadurch die Proliferation von epithelialen Zellen der Brust. Seit Längerem war schon bekannt, dass RANK und RANKL in der Metastasenbildung von Brustkrebszellen im Knochengewebe beteiligt sind. Wir konnten nun das RANK/RANKLSystem auch als essenziellen Mechanismus in der Entstehung von hormonellem Brustkrebs identifizieren. In diesem Beitrag werden wir daher den neuesten Erkenntnissen besondere Aufmerksamkeit schenken und diese kritisch in Bezug auf Brustkrebsentwicklung betrachten.

Aion, Eros e Hades nei frammenti caldaici

Directory of Open Access Journals (Sweden)

Silvia Lenzi

2006-01-01

Full Text Available The essay deals with some aspects of the knotty question concerning the presence of Aion, Eros and Hades in the variegated universe of the Chaldean Oracles, traditionally attributed to a collaboration between two “Hellenized Magi” of the second c. AD: Julian “the Chaldean” and his son Julian “the Theurgist” (even if the theurgical expertise of the elder Julian, the repository of a more ancient Chaldean tradition, might not involve a direct eastern origin but only his knowledge of “Chaldean” sciences such as astrology and divination”. Aion, who is examined here in terms of his relationship with Chronos, as a more or less autonomous divinity, is mentioned only in the context of some fragments, but his name never appears in the oracular verses. Eros (beloging also to the triad of fr. 46, along with “Faith” and “Truth” stands for an independent cosmological principle whose task is to preserve the universe and the armony of the cosmos. The Chaldean Oracles never make any explicit mention of Hades, who anyway is cited by the Byzantine scholar Psellos as an autonomous divinity of the Chaldeans.

The Danubian Eros and Thanatos in Mihail Sebastian’s Work

Directory of Open Access Journals (Sweden)

Alina Beatrice Chesca

2013-08-01

Full Text Available The present paper approaches two psychoanalytical concepts – the EROS and the THANATOS – which are extremely complex and, at the same time, fascinating due to their implications and the way they relate to the biography and work of Mihail Sebastian – the writer from the Danube. Art and biography meet in this danubian writer’s work, who tried to fight against his traumas and to heal himself through writing. The Eros and the Thanatos are omnipresent in the fiction of Sebastian’s obsessions and, when he faced destruction at an objective level, this fight resulted in anxiety and anguish. Along one’s life, there are two types of anxiety: the fear of life and the fear of death. The main theme of Sebastian’s work is that the human universe proves its strength only by suffering and that human beings can reach the ultimate dignity through their ability to endure. However, the instinct of death – the Thanatos – is always connected to the instinct of life – the Eros. We do not intend to reduce the latter one to the idea of love or passion, but we will interpret it in a broader sense – that of life, of creative energy, of light. Sebastian himself said: ”Life starts in darkness. There is a night for every day, there is a shadow for every light”.

THE FORMS OF EROS IN THE NOVEL “BARBARIUS” BY CONSTANTIN ȚOIU

Ionela-Viviana LUCA

2015-04-01

Full Text Available After a true initiatory journey, with dramatic sequences when it seemed that he lost his identity, Barbarius manages to return to his own self, the real man who can love and be loved. At the end of the novel, the protagonist achieves that much desired inner balance along with Dr. Zamfirita Micescu. However, we can not speak of eros without taking into account the desire, because the place where desire appears, also appears the needs to satisfy it. The feeling of fullness, inner balance, satisfaction manages to materialize through the harmonious fusion between the two forms of eros, namely sexuality and spiritual love. Therefore, we can state that along with Dr. Micescu, Caesar achieves a high hypostasis of eros. The narrator admirably manages to capture the reader's attention from the first chapter of the novel, which describes a passionate scene, of heartbreaking love that ends in a perverse cruelty and murder.

ASTER and USGS EROS disaster response: emergency imaging after Hurricane Katrina

Science.gov (United States)

Duda, Kenneth A.; Abrams, Michael

2005-01-01

The value of remotely sensed imagery during times of crisis is well established, and the increasing spatial and spectral resolution in newer systems provides ever greater utility and ability to discriminate features of interest (International Charter, Space and Major Disasters, 2005). The existing suite of sensors provides an abundance of data, and enables warning alerts to be broadcast for many situations in advance. In addition, imagery acquired soon after an event occurs can be used to assist response and remediation teams in identifying the extent of the affected area and the degree of damage. The data characteristics of the Advanced Spaceborne Thermal Emission and Refl ection Radiometer (ASTER) are well-suited for monitoring natural hazards and providing local and regional views after disaster strikes. For this reason, and because of the system fl exibility in scheduling high-priority observations, ASTER is often tasked to support emergency situations. The Emergency Response coordinators at the United States Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) work closely with staff at the National Aeronautics and Space Administration (NASA) Land Processes Distributed Active Archive Center (LP DAAC) at EROS and the ASTER Science Team as they fulfi ll their mission to acquire and distribute data during critical situations. This article summarizes the role of the USGS/EROS Emergency Response coordinators, and provides further discussion of ASTER data and the images portrayed on the cover of this issue

«Strong as Death is Love»: Eros and Education at the End of Time

Directory of Open Access Journals (Sweden)

Samuel D Rocha

2017-01-01

Full Text Available This essay is an extended reflection on the relationship between death and love expressed in a fragment from Song of Songs 8:6: «Strong as death is love». The passage will be analyzed through a Jewish, Orthodox, and Catholic exegesis and literary reflection. In particular, the essay describes the role of a particular form of love (eros within a particular form of education (education at the end of time. While eros has frequently been ignored or resigned to a purely sexualized role, we will look closely at Augustine’s eulogy of his mother, Monica, in the Confessions, suggesting that perhaps the most visceral expression of eros is to be found in the phenomenology of death. We will also draw on the phenomenological manifestation of death by looking to the rich description of dying provided by Leo Tolstoy in his novella, The Death of Ivan Ilych. Together these investigations of eros and education yield a «curriculum of death», which draws on the re-conceptualist notion of curriculum. Our claim is that this curriculum of death offers a sense of urgency and seriousness found lacking in schools today, where death abounds, but is rarely if ever addressed in a humanistic way. This final methodological emphasis on the humanities elucidates more directly and critically the role of research for a curriculum of death within the dominance of social science in the field of education.

Q’eros, peru: the regeneration of cosmological relationships and specific identities through Music

Holly Wissler

2010-12-01

Full Text Available One of the principal purposes of Q’eros music is to actively regenerate and re-create good relationships with the cosmos and the spirit world they believe in. In this paper, I explore how both the Q’eros’ indigenous songs as well as their newly-adopted music and dance for Peru’s largest pilgrimage, Qoyllurit’i, achieve efficacy of purpose through similar techniques of sound production and aesthetics. Even though the specific musical traits (structure, scale, and instrumentation of both musical styles are significantly different, I address how Q’eros’ musical production of both types share the same focus and serve the same end-goals, whether the ritual is an intimate one within the community or shared with thousands of other people from the greater region. In addition, the performance of both styles of music serve as specific identity markers for the Q’eros depending on their contextual use and the identity desired at the time. In other words, the Q’eros’ musical choices allow them to shift identities between traditional Q’eros in their home community and misti (mestizo in Qoyllurit’i.

The meaning of EROS/MACHO

International Nuclear Information System (INIS)

Turner, M.S.; Chicago Univ., IL

1993-01-01

Most of the mass density in the Universe and in the halo of our own galaxy -- exists in the form of dark matter. Overall, the contribution of luminous matter (in stars) to the mass density of the Universe is less than 1%; primordial nucleosynthesis indicates that baryons contribute between 1% and 10% of the critical density (0.01h -2 approx-lt Ω B approx-lt 0.02h -2 ; h = the Hubble constant in units of 100 kms -1 Mpc -1 ); and other evidence indicates that the total mass density is at least 10% of critical density, and likely much greater. If the universal density is as low as 10% of the critical density there may be but one kind of dark matter. More likely, the universal density is greater than 10%. and there are two kinds of dark matter, and thus two dark matter problems: In what form does the baryonic dark matter exist? and In what form does the nonbaryonic dark matter exist? The MACHO and EROS collaborations have presented evidence for the microlensing of stars in the LMC by 10 -1±1 M circle-dot dark objects in the halo of our own galaxy and may well have solved one of the dark matter puzzles by identifying the form of the baryonic dark matter. It is too early to make precise statements about the fraction of the mass density in the halo of our galaxy contributed by lensing objects (= f m ), though the EROS/MACHO data suggest that f m is probably 0.1 or larger. Taking our galaxy to be typical and taking account a fraction f m of the mass in the portion of the halo that contributes most significantly to microlensing (within 20 kpc of the galactic center), I estimate that lensing objects contribute a fraction 0.008f m /h of the critical density, and clearly cannot account for the bulk of the dark matter if Ω 0 much-gt 0.1

Improved ERO modelling for spectroscopy of physically and chemically assisted eroded beryllium from the JET-ILW

D. Borodin

2016-12-01

Full Text Available Physical and chemical assisted physical sputtering were characterised by the BeI and BeII line and BeD band emission in the observation chord measuring the sightline integrated emission in front of the inner beryllium limiter at the torus midplane. The 3D local transport and plasma-surface interaction Monte-Carlo modelling (ERO code [18] is a key for the interpretation of the observations in the vicinity of the shaped solid Be limiter. The plasma parameter variation (density scan in limiter regime has provided a useful material for the simulation benchmark. The improved background plasma parameters input, the new analytical expression for particle tracking in the sheath region and implementation of the BeD release into ERO has helped to clarify some deviations between modelling and experiments encountered in the previous studies [4,5]. Reproducing the observations provides additional confidence in our ‘ERO-min’ fit for the physical sputtering yields for the plasma-wetted areas based on simulated data.

Madigan, Michael E.; Weinheimer, Mary C.

1993-01-01

The vast amount of digital spatial data often required by a single user has created a demand for media alternatives to 1/2" magnetic tape. One such medium that has been recently adopted at the U.S. Geological Survey's EROS Data Center is the compact disc (CD). CD's are a versatile, dynamic, and low-cost method for providing a variety of data on a single media device and are compatible with various computer platforms. CD drives are available for personal computers, UNIX workstations, and mainframe systems, either directly connected, or through a network. This medium furnishes a quick method of reproducing and distributing large amounts of data on a single CD. Several data sets are already available on CD's, including collections of historical Landsat multispectral scanner data and biweekly composites of Advanced Very High Resolution Radiometer data for the conterminous United States. The EROS Data Center intends to provide even more data sets on CD's. Plans include specific data sets on a customized disc to fulfill individual requests, and mass production of unique data sets for large-scale distribution. Requests for a single compact disc-read only memory (CD-ROM) containing a large volume of data either for archiving or for one-time distribution can be addressed with a CD-write once (CD-WO) unit. Mass production and large-scale distribution will require CD-ROM replication and mastering.

Stereogrammetric measurement of the shape of Eros using images obtained by NEAR's Multispectral Imager provides a survey of the major topographic features and slope processes on this asteroid. This curved asteroid has radii ranging from 3.1 to 17.7 km and a volume of 2535 ?? 20 km3. The center of figure is within 52 m of the center of mass provided by the Navigation team; this minimal difference suggests that there are only modest variations in density or porosity within the asteroid. Three large depressions 10, 8, and 5.3 km across represent different stages of degradation of large impact craters. Slopes on horizontal scales of ???300 m are nearly all less than 35??, although locally scarps are much steeper. The area distribution of slopes is similar to those on Ida, Phobos, and Deimos. Regions that have slopes greater than 25?? have distinct brighter markings and have fewer large ejecta blocks than do flatter areas. The albedo patterns that suggest downslope transport of regolith have sharper boundaries than those on Phobos, Deimos, and Gaspra. The morphology of the albedo patterns, their lack of discrete sources, and their concentration on steeper slopes suggest transport mechanisms different from those on the previously well-observed small bodies, perhaps due to a reduced relative effectiveness of impact gardening on Eros. Regolith is also transported in talus cones and in connected, sinuous paths extending as much as 2 km, with some evident as relatively darker material. Talus material in at least one area is a discrete superposed unit, a feature not resolved on other small bodies. Flat-floored craters that apparently contain ponded material also suggest discrete units that are not well mixed by impacts. ?? 2002 Elsevier Science (USA).

Se a tradição cristã carregou esta palavra de forma negativa, outros Padres leram-na em sintonia com Ágape e com outros significados. A relação mística a interpreta como uma relação “erótica” entre homem e Deus. Esta intimidade procura explicar o aspecto do desejo de Deus e da relação mútua entre aquele que ama e o amado, que tem sua raiz na busca mais íntima da humanidade. Negar por preconceitos palavras carregadas de desejos não divinos e nem dignos da humanidade, como na Antigüidade, é reduzir demais seu campo semântico na história. Esta palavra reflete o amor da alma para com Deus numa perspectiva mística, assume variações significativas, dentre tantas, como o amor de Jesus Cristo, como sinônimas de Ágape, do amor de Deus para com os homens, como amor individual ligado a Deus, o Eros como virtude e como castidade. A compreensão das dimensões do amor se realiza na capacidade de ver que todas elas são positivas e importantes para obtermos o equilíbrio da vida humana, numa harmonia destas dimensões constitutivas e importantes para a vida.Palavras-chave: Eros; Patrística; Amor; Alma; Mística; Virtude; Castidade e Ágape.ABSTRACTThis article aims at demonstrating the semantics of the term Eros in Christian tradition, pointing out the limitations of the term in Portuguese.

Full Text Available La práctica del montañismo goza en la actualidad de una gran popularidad entre nuestros deportistas. Los montañeros que se mueven en grandes altitudes se ven expuestos frecuentemente a climatologías muy adversas y vías de gran dificultad física y técnica, pero posiblemente el enemigo más temible al que se tienen que enfrentar tiene que ver con los indeseables efectos de la hipoxia. La presente investigación se centra en constatar posibles deterioros en las habilidades del pensamiento de un grupo de montañeros expuesto a altitudes extremas (por encima de los 5.500 metros, sin ayuda de oxígeno suplementario. Para ello hemos contado con la participación de montañeros de tres expediciones a los “ochomiles” Manaslu, Makalu y Gasherbrum II a los que se aplicaron pruebas de aptitudes mentales antes, durante y después de cada expedición. La singularidad de nuestro estudio reside en haber incorporado resultados de pruebas realizadas en altitudes extremas, en concreto a 5.800, 6.200 y 6.000 metros respectivamente. Los resultados ponen de manifiesto que de todas las áreas y funciones cognitivas evaluadas, parece ser que las más afectadas por los efectos de la hipoxia han sido las relacionadas con la capacidad de razonamiento abstracto, espacial y verbal. Los deterioros más evidentes se observaron en altitud, persistiendo estos a la semana de regresar. Tras seis meses dichos déficits se recuperaron por completo.

Final Report on LDRD project 130784 : functional brain imaging by tunable multi-spectral Event-Related Optical Signal (EROS).

Functional brain imaging is of great interest for understanding correlations between specific cognitive processes and underlying neural activity. This understanding can provide the foundation for developing enhanced human-machine interfaces, decision aides, and enhanced cognition at the physiological level. The functional near infrared spectroscopy (fNIRS) based event-related optical signal (EROS) technique can provide direct, high-fidelity measures of temporal and spatial characteristics of neural networks underlying cognitive behavior. However, current EROS systems are hampered by poor signal-to-noise-ratio (SNR) and depth of measure, limiting areas of the brain and associated cognitive processes that can be investigated. We propose to investigate a flexible, tunable, multi-spectral fNIRS EROS system which will provide up to 10x greater SNR as well as improved spatial and temporal resolution through significant improvements in electronics, optoelectronics and optics, as well as contribute to the physiological foundation of higher-order cognitive processes and provide the technical foundation for miniaturized portable neuroimaging systems.

The study aims to explore the significance of event-related potentials (ERPs) and event-related brain oscillations (EROs) (delta, theta, alpha, beta, gamma power) in response to emotional (fear, happiness, sadness) when compared with neutral faces during 180-250 post-stimulus time interval. The ERP results demonstrated that the emotional face elicited a negative peak at approximately 230 ms (N2). Moreover, EEG measures showed that motivational significance of face (emotional vs. neutral) could modulate the amplitude of EROs, but only for some frequency bands (i.e. theta and gamma bands). In a second phase, we considered the resemblance of the two EEG measures by a regression analysis. It revealed that theta and gamma oscillations mainly effect as oscillation activity at the N2 latency. Finally, a posterior increased power of theta was found for emotional faces.

The Center for Earth Resources Observation Systems (EROS) is a field center of the geography discipline within the US geological survey (USGS) of the Department of the Interior. The EROS Data Center (EDC) was established in the early 1970s as the nation’s principal archive of remotely sensed data. Initially the EDC was responsible for the archive, reproduction, and distribution of black-and-white and color-infrared aerial photography acquired under numerous mapping programs conducted by various Federal agencies including the USGS, Department of Agriculture, Environmental Protection Agency, and NASA. The EDC was also designated the central archive for data acquired by the first satellite sensor designed for broad-scale earth observations in support of civilian agency needs for earth resource information. A four-band multispectral scanner (MSS) and a return-beam vidicon (RBV) camera were initially flown on the Earth Resources Technology Satellite-1, subsequently designated Landsat-1. The synoptic coverage, moderate spatial resolution, and multi-spectral view provided by these data stimulated scientists with an unprecedented perspective from which to study the Earth’s surface and to understand the relationships between human activity and natural systems.

A face pedagógica de Eros The pedagogical face of Eros

Como ponto de partida, está o fato de a figura do educador/professor ser comumente representado por alguém cuja ocupação não suscita desejos de qualquer espécie. Não raras vezes assistimos a representações literárias e imagens televisivas ou cinematográficas nas quais o professor aparece comicamente como uma caricatura que fala, de modo monótono e sem parar, a alunos cujos rostos oscilam entre o tédio e o escárnio. No entanto, o que é de fato assustador é que, cada vez mais, as imagens que aparecem no discurso das novas gerações, numa tentativa de oposição à caricatura supracitada, associam a figura do professor à de um animador de auditório, performático, divertido, especialista em dinâmicas grupais catárticas, sem conteúdo e igualmente caricatural. Procurando, então, desviar-se de ambas as caricaturas e refletir sobre o gênero específico de libido pedagógica - compreendido como força ou energia espiritual para o progresso moral, intelectual e sensível -, o texto recupera o poder ilustrativo do mito, pensa sobre a força do imaginário na constituição de parâmetros modelares para a Educação e para o exercício da mestria (para isso, propõe notas socráticas, sofísticas e escolásticas com ênfase na linguagem e aponta para a importância dessa discussão diante dos problemas que habitam os espaços educativos contemporâneos.The present work seeks to uncover the pedagogical face of Eros.

Searching gravitational microlensing events in the galaxy spiral arms by EROS II

1999-01-01

The EROS II experiment is searching for microlensing events due to compact massive objects passing through the line-of-sight of luminous stars. These objects are candidates to explain the baryonic component of Dark Matter in our Galaxy. EROS II was dedicated to different lines-of-sight: Small and Large Magellanic Clouds, Galactic Centre and 4 directions towards the Spiral Arms of the Galaxy. This thesis presents the first search for microlensing towards these last lines-of-sight (about 9 million stars). Simple criteria based on the search for significant fluctuations allowed one to discover a low noise sample of 7 candidates to the microlensing effect, with an average timescale of 50 days. A detailed analysis of the light curve of one candidate allows us to give a confidence interval on its mass 2.7 x 10 -3 0 0 = 50 ± 3 days. To improve the knowledge of the distance of the target stars, we have combined observations of EROS II with bibliographic sources on associations of stars linked with the spiral arm features, and we have developed a program to find variable stars. Ten cepheids have thus been found. Distances obtained with different methods are in rough agreement with each other. The average optical depth measured towards the four directions is τ-bar = 0.45 0.11 +0.23 x 10 -6 . It is compatible with expectations from simple galactic models. The long duration of most events favours interpretation of lensing by objects belonging to the disk instead of the halo. It also seems that some events due to bulge lenses have influenced measurements towards the line-of-sight which is closest to the Galactic Centre. Observation continue towards spiral arms. More accurate measurements should be obtained with increase of statistics, allowing one to estimate the disk contribution to the optical depth towards the bulge and the Magellanic Clouds. (author)

Bisphenol A (BPA) is an endocrine disruptor that may have adverse effects on human health. We recently isolated protein-disulfide isomerase (PDI) as a BPA-binding protein from rat brain homogenates and found that BPA markedly inhibited PDI activity. To elucidate mechanisms of this inhibition, detailed structural, biophysical, and functional analyses of PDI were performed in the presence of BPA. BPA binding to PDI induced significant rearrangement of the N-terminal thioredoxin domain of PDI, resulting in more compact overall structure. This conformational change led to closure of the substrate-binding pocket in b′ domain, preventing PDI from binding to unfolded proteins. The b′ domain also plays an essential role in the interplay between PDI and ER oxidoreduclin 1α (Ero1α), a flavoenzyme responsible for reoxidation of PDI. We show that BPA inhibited Ero1α-catalyzed PDI oxidation presumably by inhibiting the interaction between the b′ domain of PDI and Ero1α; the phenol groups of BPA probably compete with a highly conserved tryptophan residue, located in the protruding β-hairpin of Ero1α, for binding to PDI. Consistently, BPA slowed down the reoxidation of PDI and caused the reduction of PDI in HeLa cells, indicating that BPA has a great impact on the redox homeostasis of PDI within cells. However, BPA had no effect on the interaction between PDI and peroxiredoxin-4 (Prx4), another PDI family oxidase, suggesting that the interaction between Prx4 and PDI is different from that of Ero1α and PDI. These results indicate that BPA, a widely distributed and potentially harmful chemical, inhibits Ero1-PDI-mediated disulfide bond formation. PMID:25122773

The prediction of the first wall deterioration and possible plasma contamination by impurities is a high priority task for ITER. 3D Monte-Carlo code ERO is a tool for modeling of eroded impurity transport and spectroscopy in plasma devices useful for experiment interpretation. Chromium (Cr) is a fusion-relevant reactor wall element (e.g. component of RAFM steels expected for use in DEMO). Linear plasma devices including PSI-2 are effective tools for investigations of plasma-surface interaction effects, allowing continuous plasma operation and good control over irradiation parameters. Experiments on Cr sputtering were conducted at PSI-2. In these experiments the Cr erosion was measured by three techniques: mass loss of the sample, quartz micro-balance of deposited impurities at a distance from it and optical emission spectroscopy. Experiments were modeled with the 3D Monte-Carlo code ERO, previously validated by application to similar experiments with tungsten (W). The simulations are demonstrated to reproduce the main experimental outcomes proving the quality of the sputtering data used. A significant focuses of the paper is the usage and validation of atomic data (resent metastable-resolved dataset from ADAS) for interpretation of Cr spectroscopy. Initial population of quasi-metastable state was fitted by matching the modeling with the experimental line intensity profiles.

Full Text Available The Challenge of the Sexual Labyrinth Sensuality in the Work of Italo CalvinoIn this article, the novels, stories and essays of Italo Calvino are being studied from the perspective of sensuality and Eros. In literary criticism Calvino’s work is rarely being associated with sexuality, even though the subject did fuel the imagination of the writer himself. Calvino recognized the importance of the theme of sexuality in literature as well as the challenge inherent in trying to depict faithfully a similar ineffable subject, that has, moreover, been covered by society under a thick layer of clichés and repetitive language and therefore been emptied of meaning. The importance of a non-banal, renewing sexuality in literature inspired Calvino to experiment in a light, humorous, surprising way with a myriad of forms of literary sensuality. Calvino has searched Eros in space, as the prime mover in evolution, amongst animals and celestial bodies (instead of the usual heavenly bodies, in rituals and objects, in the heads of his characters, but seldom there where the reader would expect it to be. In a mild and often indirect way Calvino integrates his reflections on the subject in his short stories and comments on the role of sexuality in modern society and literature.

Eros and Thanatos: A Nondualistic Interpretation: The Dynamic of Drives in Personal and Civilizational Development From Freud to Marcuse.

Kli, Maria

2018-02-01

The Freudian theory of drives gave prominence to the idea that there is an inherent principle of entropy, a tendency for dissolution of life, referred to as the Death drive, or Thanatos. Freud recognized a counterbalancing tendency for sustaining life, known as the Life drive, or Eros. The psychoanalytical expounding of the struggle of Eros and Thanatos in the context of the civilizational process sparked the philosophical critique of civilization. Although Freud tended to consider repression an indispensable dimension of this process, the author proposes in this paper that Herbert Marcuse's political critique took Freud's metapsychology further philosophically, suggesting a nondualistic interpretation of Freud's position.

In den Ergebnissen aktueller Evaluationen zeigen sich Bestrebungen nach Qualität von Bildungs- und Lernprozessen. Empirische Forschung kommt die Aufgabe zu medienpädagogische Wirkungsgrade und Zielerreichung zu überprüfen und zu kontrollieren. Quantitative Forschungsmethoden ermöglichen es Mediennutzungsverhalten bestimmter Zielgruppen in Wechselwirkung mit Programmstrukturen und -inhalten zu ermitteln. Nutzungsmuster von Medienangeboten – vor allem bei Kindern und Jugendlichen – sind auch bei der Entwicklung medienpädagogischer Ansätze wichtig.

Full Text Available Aristophanes links Eros to peace in his comedies. In Acharnians, 425 BC, Dikaeopolis, an Athenian citizen, obtains private truce with the Spartans for himself and his family. He does not share his peace with anyone else, except with a bride, because she is  a woman and not is blamed for the war. It will have part of the fiance in their wedding. In Peace, 421 BC, Trigeu a grape-gatherer solves fly in a scarab beetle, who eats feces, to speak to the gods for peace, and ends up rescuing the Eirene goddess (Peace, contained in a cave by Polemos (War. Peace brings the goddess Opora (Autumnal or Harvest, with whom the protagonist marries, and the goddess Theoria (Feast, which is given to prytanes in the theater itself. In Lysistrata, in 411 BC, the women of Greece under the leadership of the Athenian Lysistrata make a sex strike to force their husbands to end up the war. The Myrrhine character and her husband, Kinesias, demonstrate how is the seduction and the refusal of women compared to men. We propose to link Eros to peace in the three pieces presented and Thesmoforiazusai (Demeterkoreazusai, the same year of Lysistrata and very close to it in some important ways, such as bringing a female choir, performing the separation of couples, making the apology of women and promote peace, because it is a religious festival of fertility, the Thesmophoria, parties in honor of the goddesses Demeter and Kore.

Full Text Available Apesar de haver significativa variabilidade espacial e temporal nas variáveis de modelos de predição de erosão, mesmo em áreas consideradas homogêneas, ela é raramente incorporada na análise e no planejamento conservacionista. As consequências dessa simplificação são predições incorretas de perda de solo, com implicações para a sustentabilidade agrícola e ambiental de glebas. Os objetivos deste trabalho foram: (a estimar o efeito da variabilidade espacial e temporal dos fatores da Equação Universal de Perdas de Solo - USLE na predição da erosão em uma área homogênea situada no Distrito Federal; (b incorporar a incerteza resultante no processo de tomada de decisão conservacionista; e (c propor medidas para sua mitigação. Os resultados indicam que, apesar do baixo coeficiente de variação médio dos fatores da USLE na área estudada, na faixa de 20 %, o coeficiente de variação da perda de solo (A estimada foi de 64 %, indicando significativa propagação de incerteza no modelo. A implicação disso é que, mesmo sendo o valor médio de A 19 % menor que o limite médio de tolerância à erosão na gleba (T, haveria ainda uma probabilidade de 43 % de que A fosse superior a T. Para reduzir esse risco, são sugeridas medidas que aumentem a margem de segurança do sistema, como a adoção de práticas conservacionistas. Com a introdução de terraços, a probabilidade de falha do sistema seria reduzida para 12 %. Os resultados reforçam a importância da incorporação das variabilidades e incertezas na estimativa da erosão e no planejamento conservacionista, por meio de análise estocástica.

ERO is a Monte-Carlo code for modeling plasma-wall interaction and 3D plasma impurity transport for applications in fusion research. The code has undergone a significant upgrade (ERO2.0) which allows increasing the simulation volume in order to cover the entire plasma edge of a fusion device, allowing a more self-consistent treatment of impurity transport and comparison with a larger number and variety of experimental diagnostics. In this contribution, the physics-relevant technical innovations of the new code version are described and discussed. The new capabilities of the code are demonstrated by modeling of beryllium (Be) erosion of the main wall during JET limiter discharges. Results for erosion patterns along the limiter surfaces and global Be transport including incident particle distributions are presented. A novel synthetic diagnostic, which mimics experimental wide-angle 2D camera images, is presented and used for validating various aspects of the code, including erosion, magnetic shadowing, non-local impurity transport, and light emission simulation.

Sylvia Plath - a woman between Eros and Thanatos

Barbara Galle

2005-12-01

Full Text Available The opposition between the Hughes family  and the radical feminists led to the emergence of two diametrically opposite Plath  myths: a mentally disturbed, manipulative woman, unstoppably driven towards suicide, or an innocent victim of a treacherous husband? Both sides interpret Plath's life and works in view of her untimely  death, neglecting the underlying life force that pervades her poetry and prose. Relying on the psychoanalytical theory of instincts, the author shows how Eros complements and even makes use of Thanatos on different levels of Plath's writing:  on the level of language asa meaningful structure, on the level of meaning, and in the function of language as therapy. The duality of instics is particulary evident in Sloveirian criticism; where the physicar  and temporal distance from political scandal enabled the development oftwo distinct critical currents: one following Hughes's morbid determinism, the other concentrating on Plath's intelligence and joyful observation of nature.

Ziel der vorliegenden retrospektiven Untersuchung war die Erfassung genetischer Aberrationen an paraffineigebettetem Material primärer Prostatakarzinom-Biopsien und die Korrelation der Daten zum klinischen Verlauf. In 28 karzinomtragenden primären Prostatabiopsien wurden die Tumorareale gekennzeichnet. Nach Dissektion der Tumorzellen wurden die Proben mittels "comparative genomic hybridization" (CGH analysiert. Daten zum klinischen Verlauf der Patienten wurden erfaßt. Die mittlere Nachbeobachtungszeit betrug 36 Monate, alle Patienten wurden hormonablativ behandelt. 11 Patienten (39 % wiesen unter laufender Therapie einen Tumorprogreß auf. In 25 (88 % der 28 untersuchten Tumorareale konnten genetische Aberrationen detektiert werden, im Mittel fanden wir 4,8 Aberrationen je Tumor. Das Verhältnis Verlust / Zugewinn betrug 1,3 / 1. Folgende chromosomale Veränderungen wurden häufig festgestellt: Verluste von 6q in 40 %; von 8p in 32 %; von 16q in 21 %; von 18q in 21 %; Zugewinne von 8q in 32 %; von 17 in 43 %. In Korrelation zum klinischen Verlauf fand sich ein Zugewinn von 8q signifikant häufiger bei Patienten, welche im Beobachtungszeitraum einen Tumorprogreß entwickelten (64 % vs. 12 %; p = 0,0001. In der primären Tumorbiopsie waren bei progredienten Patienten im Mittel 5,3, bei Patienten ohne Tumorprogreß 3,8 Aberrationen je Tumor nachzuweisen. Unsere Ergebnisse zeigen, daß Veränderungen der Chromosomen 6q, 8, 16q, 17 und 18q regelmäßig beim Prostatakarzinom auftreten. Karzinome mit klinisch ungünstigem Verlauf weisen bereits in der primären Biopsie eine hohe genetische Instabilität auf.

Experiments at JET showed locally enhanced, asymmetric beryllium (Be) erosion at outer wall limiters when magnetically connected ICRH antennas were in operation. A first modeling effort using the 3D erosion and scrape-off layer impurity transport modeling code ERO reproduced qualitatively the experimental outcome. However, local plasma parameters—in particular when 3D distributions are of interest—can be difficult to determine from available diagnostics and so erosion / impurity transport modeling input relies on output from other codes and simplified models, increasing uncertainties in the outcome. In the present contribution, we introduce and evaluate the impact of improved models and parameters with largest uncertainties of processes that impact impurity production and transport across the scrape-off layer, when simulated in ERO: (i) the magnetic geometry has been revised, for affecting the separatrix position (located 50-60 mm away from limiter surface) and thus the background plasma profiles; (ii) connection lengths between components, which lead to shadowing of ion fluxes, are also affected by the magnetic configuration; (iii) anomalous transport of ionized impurities, defined by the perpendicular diffusion coefficient, has been revisited; (iv) erosion yields that account for energy and angular distributions of background plasma ions under the present enhanced sheath potential and oblique magnetic field, have been introduced; (v) the effect of additional erosion sources, such as charge-exchange neutral fluxes, which are dominant in recessed areas like antennas, has been evaluated; (vi) chemically assisted release of Be in molecular form has been included. Sensitivity analysis highlights a qualitative effect (i.e. change in emission patterns) of magnetic shadowing, anomalous diffusion, and inclusion of neutral fluxes and molecular release of Be. The separatrix location, and energy and angular distribution of background plasma fluxes impact erosion

Nesse domínio as marcas são utilizadas pelas empresas como estratégia para criar valor e diferenciação, para que possam se distanciar dessa concorrência. Marcas fortes tendem a criar uma vantagem competitiva duradoura (Tavares, 1998; Bedbury, 2002; Keller & Machado, 2006; Aaker, 2007; Scharf, 2007. Porém, mesmo consolidadas no mercado, marcas sólidas estão vulneráveis aos fatores que causam sua erosão. Nesse contexto, este artigo pretendeu estabelecer a percepção dos fatores de erosão no processo de construção de marcas sólidas, analisando as ações estratégicas incorporadas e trabalhadas pela marca Samsung no Brasil. Para responder as indagações ostentadas, foram utilizados dados primários instaurados nas entrevistas realizadas com executivos estrategistas da marca, e informações advindas também de dados secundários com análise documental de artigos publicados sobre a marca investigada. Quanto aos fatores de erosão estabelecidos, alguns foram percebidos integralmente como erosivo pelos executivos, como é o caso da Proliferação de concorrentes e Pressão por resultados a curto prazo. Com a análise das informações se abarcou o estabelecimento de outros fatores que causam erosão na perspectiva de marca no contexto brasileiro.

The following statements were added or modified: The procedure guideline discusses the pros and cons of a single measurement or of repeated measurements of the iodine-131 uptake and their optimal timing. Different formulas are described when one, two or three values of the radioiodine kinetic are available. The probe with a sodium iodide crystal, alternative or additionally the gamma-camera using the ROI-technique are instrumentations for the measurement of iodine-131 uptake. A possible source of error is an inappropriate measurement (sonography) of the target volume. The patients' preparation includes the withdrawal of antithyroid drugs 2-3 days before radioiodine administration. The patient has to avoid iodine-containing medication and the possibility of additives of iodide in vitamin- or electrolyte-supplementation has to be considered. (orig.)

Beides, Nähe und Distanz, wird dabei nicht als innere Haltung von Forschenden oder als rigoros nationaler Stil verstanden, sondern als Produkte konkreter Arbeitspraktiken, die in Zusammenhang mit nationalen Forschungskonventionen, Rahmenbedingungen und Epistemologien stehen. Gemeinsam ist beiden Interaktionsmustern die zentrale Fundierung im amerikanischen Pragmatismus, wobei die These einer auffallend unterschiedlichen Bezugnahme auf den amerikanischen Pragmatismus in den beiden Länderkontexten diskutiert wird: Stehen in Deutschland vorwiegend dessen erkenntnistheoretische Prämissen im Mittelpunkt, sieht sich die gegenwärtige US-amerikanische Methodenlandschaft eher dessen gesellschaftspolitischen Traditionen verpflichtet.

Dadas las diferencias entre ambas plataformas, en este artículo nos centramos en el curso de la plataforma Miríada X, cuyo planteamiento se basó principalmente en una serie de actividades de lengua interculturales que buscaban la interacción y el feedback entre compañeros, con el objeto de fomentar la comunicación en línea en la lengua de destino y desviar el enorme desequilibrio en la proporción entre estudiantes (cerca de 30.000 y profesores (5: 2 curadores y 3 facilitadores y el elevado índice de abandono característico de este tipo de cursos. La información sobre el nivel de interacción alcanzado y el feedback proporcionado por los estudiantes se registró mediante la observación del seguimiento del curso y las opiniones de los estudiantes recogidas en un cuestionario final. El análisis realizado revela la necesidad de matizar algunos de los actuales criterios de calidad de estos cursos y de mejorar sustancialmente la percepción de los estudiantes de lenguas sobre la interacción con compañeros.

The TESIS Project: Are Type 2 QSO Hidden in X-Ray Emitting EROs?

X-ray selected EROs are, on average, the hardest X-ray sources in medium and deep X-ray fields. This coupled with their extremely red colors (R-K > 5) suggest that they represent one of the most promising population where looking for high-luminosity (LX > 1044 erg s-1) and X-ray obscured (NH > 1022 cm-2) type2 AGNs, the so called QSO2 (e.g., [5]; [4]; Mignoli et al. submitted to A&A). These latter are predicted in large density by the synthesis model of the Cosmic X-ray background [9] even if only few observational evidences have been found so far (e.g., [1] and references therein; Caccianiga et al. A&A accepted).

Full Text Available A inexistência de planejamento no que se refere à expansão urbana é uma realidade enfrentada por várias cidades brasileiras. A ocupação desordenada pode acarretar diversos problemas, a exemplo da erosão, que nas cidades tem se tornado um acontecimento cada vez mais frequente e intenso. A identificação das áreas que apresentam susceptibilidade à ocorrência de algum desastre é considerada um importante procedimento na gestão de riscos ambientais e, consequentemente, vem a colaborar de maneira relevante nas questões do planejamento urbano. É neste sentido que o presente trabalho teve como objetivo determinar as diretrizes iniciais de crescimento da área urbana do município de Ubá, Minas Gerais, a partir da vulnerabilidade à erosão do seu perímetro urbano. Foi realizado o cruzamento de mapas de uso e ocupação do solo, geomorfologia, solos e declividade para obtenção do mapa de susceptibilidade à erosão da área de estudo. A partir deste mapa foram estabelecidas as diretrizes iniciais para o crescimento do município estudado. Os eixos norte, sul e oeste, em relação ao perímetro urbano, foram considerados inadequados para o crescimento da cidade. O eixo leste foi aquele mais adequado para o crescimento urbano desse município.

Networking of power plant computer systems is becoming increasingly common. Furthermore, instrumentation and control systems are being connected with general power plant networks to make process information available to administrative personnel. This increases the risk of accidental or intentional access from outside the system (e.g. by hackers). Firewall systems are used to prevent such outside access.

2009-10-01

Full Text Available Thus, in this paper I would like to explore the idea of spiritual longing in otaku culture, firstly, by elucidating Plato’s eros and Otto’s numinous, and then, secondly, by examining a few examples from anime and manga which have instilled in me, or others I know, a deep desire for something that can only be described as mysterious, irreducible and spiritual. Used examples are drawn from the family-orientated anime My Neighbor Totoro, the shōnen anime Gundam, and the shōjo manga Sailor Moon.

Full Text Available The beryllium erosion by helium plasma irradiation is studied at the PISCES-B linear plasma device and interpreted using the accompanying simulations by the ERO code. The influence of plasma conditions and varying negative biasing of the Be plasma target on BeI and BeII absolute line intensities are reproduced in detail by the simulations. The synthetic axial line intensity shapes and line ratios match with experiment. This indicates that atomic data are quite accurate. The initial population state of quasi-metastable 3P level in BeI is found to be MS:GS= 0.33:1 for all conditions. The yields determined by the modeling interpretation are compared to the SDTrimSP code simulations in the binary collision approximation.

Full Text Available In Deutschland zeichnet sich bereits vor Schuleintritt im Bereich der literarischen und medialen Sozialisation eine Bildungsbenachteiligung ab. Vor allem Kinder aus bildungsfernen Milieus und mit Migrationshintergrund sind hiervon betroffen (vgl. Becker/Lauterbach 2004; Diefenbach 2007; Rabe-Kleberg 2010. An dieser Einsicht knüpft das Forschungs- und Interventionsprojekt KidSmart – Medienkompetent zum Schulübergang an. Medienpädagogische Arbeit steht hier im Kontext der Vorbereitung auf den Schulübergang. Durch kreative Medienarbeit soll ein Gegengewicht zur eher passiven Mediennutzung geschaffen werden. Ziel ist es Bildungsunterschiede von Kindern bereits vor Schulbeginn auszugleichen.Already before starting school educational disadvantages in the part of reading and media socialization can be identified within Germany. Generally affected are children of less educated families and children with migration background (Becker/Lauterbach 2004; Diefenbach 2007; Rabe-Kleberg 2010. Therefore, an exceptional intervention and research project KidSmart – media competence by entering school was initiated in the area of early childhood education. Within this project media-pedagogical work is corresponding with preparation of entering school. The intention is to create a counterbalance to passive media use by creative media work. The scope of the project is to fight against early educational disadvantages.

Os fatores de erosão locais, como erosividade (R, erodibilidade (K, relevo (LS, perda de solo (A, potencial natural de erosão (PNE, risco de erosão (RE e expectativa de erosão (EE, foram avaliados. A variabilidade do solo medida pelo coeficiente de variação registrou-se média para K, alta para o RE e EE e muito alta para A, LS e PNE. As variáveis estudadas apresentaram estrutura de dependência espacial com grau moderado para as variáveis K, A, PNE e RE, e forte para o LS e EE. Mapas obtidos por krigagem foram apresentados para descrição dos padrões de distribuição dos fatores de erosão na paisagem.The objective of this work was to evaluate the spatial variability of soil erosion factors on a Dark Red Oxisol under sugarcane conventional tillage. Soil samples were collected in 206 points, in a depth of 0.0-0.2 m, located in a 50 m regular grid for obtaining the soil texture and organic matter content. The local erosion factors were determined: erosivity (R, erodibility (K, relief (LS, soil erosion (A, natural potential of erosion (PNE, erosion risk (RE and erosion expectation (EE. Geostatistical analysis was performed to measure and model the spatial variability of soil erosion factors. The soil variability was moderate with K, A, and PNE while the soil variability was higher with LS, RE, and EE. K, A, and PNE exhibited moderate spatial dependence, but spatial dependence of LS, RE and EE was strong. Kriging maps were presented for understanding of soil erosion factors distribution patterns within the landscape.

Full Text Available Embora existam vários estudos ligados às questões ambientais voltadas para a poluição atmosférica, ao uso crescente da biotecnologia e à mecanização do processo de colheita da cana-de-açúcar, a mesma atenção não tem sido dada aos impactos ambientais negativos promovidos pela erosão laminar. O presente trabalho teve como objetivo avaliar a concentração de matéria orgânica (MO e nutrientes (P, K, Ca e Mg em sedimentos e na água da enxurrada proveniente de erosão entre sulcos em diferentes sistemas de manejo na colheita da cana-de-açúcar utilizados no Estado de Mato Grosso do Sul (cana crua e queimada, sob um Latossolo Vermelho distrófico de textura média. Os tratamentos estudados foram colheita manual de cana queimada, colheita mecanizada de cana crua e colheita mecanizada de cana queimada. Aplicou-se chuva simulada com intensidade de 60 mm h-1, durante 50 min. As concentrações de sedimentos na enxurrada resultantes da erosão entre sulcos, bem como de MO, P, K, Ca e Mg, foram maiores no sistema com colheita mecanizada de cana queimada e menores no sistema com colheita mecanizada de cana crua. A qualidade física do solo sofre influência negativa do sistema de manejo com colheita mecânica de cana queimada, devido ao efeito da pressão exercida pelo tráfego de máquinas na colheita. No entanto, os resíduos vegetais de colheita distribuídos na superfície do solo pela colheita mecânica de cana crua reduzem as perdas de nutrientes e de MO no sedimento, além de aumentarem a capacidade do solo em resistir à degradação física ocasionada pelo tráfego de máquinas na colheita mecanizada de cana.

Search for type Ia supernovae within the EROS2 collaboration. Photometric study of nearby SNIa and measurement of H_0

International Nuclear Information System (INIS)

Regnault, Nicolas

2000-01-01

Type Ia supernovae (SNIa) are powerful distance indicators. The comparison of nearby (z ∼ 0:1) and distant (z ∼ 1) SNIa apparent magnitudes leads to the determination of the large scale geometry of the universe. Cosmological parameters such as the Hubble constant H_0, the matter density Ω_m and the cosmological constant Ω_Λ can thus be determined. The EROS2 experiment devotes about 10% of its observing time to the detection of nearby SNIa. In the spring of 1999, EROS2 participated in a worldwide search conducted by the Supernova Cosmology Project. This campaign resulted in the discovery of 50 supernovae. Among these, 20 turned out to be SNIa discovered within 10 days from maximum. The thesis work is divided into 3 parts. First, we present a quick overview of the standard cosmological model and the main techniques used for measuring the cosmological parameters (SNIa, rich clusters properties, and anisotropies of the cosmological background radiation). We then describe the physics and observational properties of SNIa. In particular, we show that the peak absolute luminosity of these objects is uniform (within 30%), and correlates with other observables. Using these correlations, we can construct a corrected peak luminosity, which exhibits a lower dispersion (∼10%). The second part is devoted to the description of the EROS2 setup, and our SNe search techniques. In the last part, we present the analysis of the spring 1999 SNIa's photometric follow-up data. We describe the photometry software developed for this analysis as well as the complex intercalibration process of the follow-up images taken with 10 different telescopes. In the last chapter, we show how the peak luminosity and the decline rate of each SN can be reconstructed. Using these quantities, we study the correlations between the peak luminosity the decline rate and the color of SNIa, which leads to a value of H_0: H_0 = 67.4 ± 2(int)"+"5"."8_-_6_._4(ext.).

O delineamento experimental foi inteiramente casualizado com seis repetições. Os tratamentos constaram de: preparo convencional recente (CR, preparo convencional consolidado (consolidação de dois meses (CC, plantio direto sem palha (PDS e plantio direto com palha (PDC, 94% de cobertura. Usou-se chuva simulada de intensidade constante (65 mm h-1 até escoamento aproximadamente constante de água no solo. Em seguida, na extremidade superior do sulco, foram adicionadas descargas líquidas (Q crescentes de 0,0002 m³ s-1 até 0,0010 m³ s-1, para os tratamentos CR e CC, e de 0,0004 m³ s-1 até 0,0020 m³ s-1, para os tratamentos PDS e PDC, sendo as amostras coletadas na parte inferior de cada sulco. As parcelas foram delimitadas por chapas metálicas cravadas no solo no sentido do declive (0,20 m de largura por 6,00 m de comprimento. O valor de Kr determinado foi de 0,012 kg N-1 s-1 e o τc foi de 2,61 N m-2. A desagregação, as perdas de solo e o diâmetro mediano dos sedimentos apresentaram a seguinte seqüência em magnitude: CR, CC, PDS e PDC, particularmente nas maiores Q. O regime de escoamento foi turbulento supercrítico, com exceção da primeira Q aplicada, onde o regime foi laminar subcrítico, para o PDC, graças à presença de resíduos culturais, e laminar supercrítico, para os demais tratamentos. A consolidação e a cobertura do solo alteram o regime do escoamento e reduzem a erosão em sulcos e seus efeitos são complementares.

A trend towards increasingly new forms of dental practice has been observed in the FDI World Dental Federation. Elementary foundations such as the free dentist and therapy choice, and independent, free, self-responsible professional practice may be undermined. The current study is aimed at analyzing the general training framework, organization, and professional types of dental practice in the European Regional Organization (ERO) zone and at critically discussing selected aspects of changes in the dental profession. A questionnaire was developed by the ERO Working-Group "Liberal Dental Practice." Information about dental schools, professional organizations, dental practice regulations, and ambulatory healthcare centers was analyzed. Self-employed dental practice is the most common type of practice (51.7%). Dentists are allowed to work independently immediately after graduation (72.7%). Approximately one-third are organized as compulsory members in chambers/corporations. The density of dentists has a mean of 1,570 inhabitants per dentist. In most countries, there are no special rules for founding dental ambulatory healthcare centers. In a total of 353 universities of the ERO countries surveyed, 16,619 dentists per year were trained, with a trend toward a higher percentage of female students (63%). Despite modern forms of dental practice, the charter of the individual liberal dental profession (CED et al, 2013) should be respected and taken into account on the basis of ethical principles. The commercialization of the dental profession can be neutralized only by establishing and following well-defined ethical principles; oral healthcare quality can thus be ensured without the influence of third parties.

Os tratamentos, aplicados antes da semeadura de trigo e de soja, cultivados em sucessão, foram: (i escarificação + gradagem niveladora (ES, (ii gradagens pesada + niveladora (GP, (iii plantio direto (PD e (iv aração com arado de discos + duas gradagens niveladoras, sem cobertura vegetal (DE. O preparo de solo e a semeadura foram realizados no sentido do declive. O PD foi o tratamento mais eficiente, tanto no controle de perdas de solo e de água quanto em rendimentos de grãos de soja e de trigo. As perdas médias de solo e de água por erosão, relativas aos sistemas PD, ES, GP e DE, foram, respectivamente, de: 0,8; 2,8; 5,3 e 7,3 t ha-1 ano-1 e 27, 80, 112 e 149 mm ano-1. O PD, quando comparado ao DE, controlou 89% das perdas de solo e 82% das de água. O PD mostrou rendimentos médios de grãos, tanto de soja como de trigo, 17% superiores aos do GP. O ES apresentou rendimentos médios 5% superiores em soja e 12% superiores em trigo, quando comparados aos do GP. Este último, dos tratamentos cultivados, foi o menos eficaz, seja no controle à erosão, seja nos rendimentos de soja e trigo. O fator erosividade, R, foi estimado em 6.411 MJ mm ha-1 h-1 ano-1, e a erodibilidade, K, foi de 0,0045 t h MJ-1 mm-1. Entre junho/94 e maio/95, o período de maior intensidade de perdas por erosão por unidade de tempo foi do preparo de solo à semeadura da soja, e o de maiores perdas absolutas foi o de 30 a 60 dias após a semeadura dessa cultura. Isso demonstra a importância de adequada cobertura do solo, entre novembro e março, e reforça a recomendação do Sistema de Plantio Direto para a região de Dourados (MS.

Eigentliches Ziel der Arbeit ist es, Foucaults Beitrag zur Rechtsgeschichte und –soziologie zu beleuchten. Diese Thematik ist im deutschen Sprachraum bis jetzt kaum systematisch untersucht worden, und dementsprechend gebührt Schauers Studie besondere Beachtung. Der Autor betont Foucaults Ausführungen zum Verhältnis zwischen Recht und Psychiatrie. Dessen Diagnose hebt die “Kolonisierung” des Rechts durch forensisch psychiatrische Diskurse hervor, und Schauer gelingt es, die problematische Dimension dieser Tendenz mit Hinweis auf die schweizerische Rechtspraxis plausibel zu machen. Fluchtpunkt dieser Entwicklung wäre ein bis zum Extrem “vorbeugendes” Recht, das Gefahrenprävention und Risikoregulierung durch präemptive Verhaltensregulierung den Vorzug vor dem Legalitätsprinzip gewährt.

Full Text Available Há poucos estudos sobre a história da ciência do solo e, no Brasil, essa matéria ainda não recebeu maior atenção por parte de sua comunidade científica. Este trabalho focaliza a formação histórica da pesquisa brasileira em erosão acelerada do solo a partir de uma análise bibliométrica e geográfica, com base numa ampla compilação de artigos científicos publicados sobre o tema por autores vinculados a instituições brasileiras. A metodologia envolveu o armazenamento, em um banco de dados dimensional, estruturado especificamente para esse objetivo, de informações espaciais e bibliométricas. Indicadores quantitativos foram calculados, e a geografia da pesquisa foi mapeada por meio de consultas SQL e ferramentas de geoprocessamento. Os resultados apontaram para gênese recente da pesquisa brasileira em erosão acelerada do solo e centralização da produção científica e formação de linhas em instituições e autores do Sul e Sudeste do Brasil. Ainda, a análise dos dados temáticos indicou predominância do enfoque da erosão a partir de uma perspectiva agrícola e grande ênfase na pesquisa dos fatores do modelo USLE de estimativa de erosão.Soil science history studies are rare and the Brazilian scientific community has not given substantial attention to this subject yet. The present study focused on the formation of research on accelerated soil erosion in the Brazil from a bibliometric perspective.

These data were used to calculate quantitative indicators and spatial distribution patterns. Results indicate a recent development of research on accelerated soil erosion in Brazil by few institutions and authors in the South and Southeast regions. Moreover, a thematic analysis indicated the agricultural perspective as the main focus of erosion studies, with a great emphasis on the USLE

Full Text Available Dentre as formas de erosão hídrica do solo, a erosão em entressulcos é uma das que causam maiores danos no processo produtivo dos solos utilizados na agricultura, por provocar perdas de solo, água e nutrientes. Frente a isso, o presente trabalho visou avaliar a proteção ambiental promovida pela cobertura vegetal da caatinga, do feijão-guandu (Cajanus cajan e da batata-doce (Ipomoea batatas Lam em relação ao solo descoberto, bem como o efeito das práticas de cultivos dessas culturas, por meio das taxas da erosão em entressulcos e das características hidráulicas do escoamento superficial vinculado à erosão em entressulcos, em um Luvissolo. Para isso, foi implementada uma série de 20 chuvas simuladas em Serra Talhada, município do semi-árido do Estado de Pernambuco, sob os seguintes tratamentos: (1 solo descoberto; (2 solo coberto pela cultura do feijão-guandu (Cajanus cajan; (3 solo coberto pela cultura da batata-doce (Ipomoea batatas Lam.; (4 solo coberto por Caatinga semi-arbustiva. Todos os regimes de escoamento superficial obtidos foram laminar lento. As coberturas vegetais proporcionadas pela Caatinga e pelo guandu, que deram origem aos maiores valores de cobertura do solo, responderam pelas menores taxas de concentração de sedimentos e desagregação do solo na erosão em entressulcos, em decorrência da maior rugosidade hidráulica da superfície do solo promovida por essas vegetações. As taxas de concentração de sedimentos no cultivo da batata-doce foram iguais às do solo descoberto, por conta do revolvimento do solo na preparação das leiras de plantio, e determinou as maiores taxas de desagregação do solo entre as coberturas vegetais; em contrapartida, as leiras permitiram retenção do escoamento superficial. As coberturas vegetais Caatinga, guandu e batata-doce e as respectivas rugosidades hidráulicas impostas ao escoamento superficial determinaram reduções exponenciais das perdas de solo. A cobertura

La historiografía ha considerado este texto como una obra de historia de la literatura; también como un trabajo "liberal". Carácter de la literatura sería en realidad una obra de filosofía social positivista. Pero sería además una versión peruana del positivismo monarquista royaliste. Riva-Agüero habría tenido un referente oculto: el libro de filosofía social positivista de Javier Prado, Estado social del Perú durante la dominación española (1894, que habría puesto de cabeza. Tres temas básicos eran el eje de una oculta polémica político-conceptual: la religión, la monarquía y la tradición. Una oculta teoría de psicología colectiva le serviría de sustento: los peruanos tendrían un carácter pragmatista y un sentimiento social empático con el pasado, más apropiado para reivindicar la tradición que para condenarla. La Guerra del Pacífico y un baile social de la aristocracia de la Lima de 1904 serán el escenario de la controversia.

Full Text Available Das vorliegende Heft der Zeitschrift MedienPädagogik umfasst vor allem Beiträge, die aus der Sicht der qualitativen Forschung geschrieben wurden. Das war nicht unbedingt die Absicht des Herausgebers. Doch alle Beiträge, die uns auf Grund unseres «calls for paper» erreichten, bezogen sich auf Thematiken im Rahmen der Begründung und Diskussion qualitativer Forschungsverfahren. Wir sehen darin einen Ausdruck der Tatsache, dass in den letzten Jahren die Methoden einer qualitative Forschungsmethodologie zunehmend salonfähig geworden sind. Gerade wenn man Medienereignisse unter dem Gesichtspunkt aktiver Rezipienten betrachtet, die nicht einfach Opfer von externen Reizen sind, dann bietet es sich an, diese Interaktivität mit qualitativer Mitteln zu untersuchen. Möglich sind z. B. teilnehmende Beobachtung, Tiefen- oder Gruppeninterviews. All diesen Verfahren ist gemeinsam, dass die Forschenden in eine intensive Beziehung zu ihrem Gegenstand eingetreten, wie sie über die objektivierenden Verfahren der klassischen Empirie kaum möglich ist. Eine zweites Merkmal qualitativer Forschung ist es, dass es in solchen Untersuchungen oft weniger um die Überprüfung von Theorien geht, sondern um deren Entwicklung. Kleine Gruppen eignen sich besonders, um im Kontakt mit den Daten theoriegenerierende Arbeit zu leisten. Das Konzept der «grounded theory» betont z. B. explizit, dass damit ein Weg verbunden sei, um Theorien aus den untersuchten Fällen heraus zu entwickeln. Was drittens besonders zur einer medienpädagogischen Zeitschrift passt, ist der Umstand, dass in dieser Nummer auch Möglichkeiten eines Einbezug von visuellen Verfahren in qualitative Forschungsaktivitäten diskutiert wird. Damit wird signalisiert, dass Medien nicht nur Gegenstand dieser Zeitschrift sind, sondern - wie im Rahmen von Videoanalysen - auch ein Instrument in der Hand von Forscher/innen sein können, um den «Untersuchungsgegenstand» nicht allein über schriftliche Texte

The project's objective was the optimization of a novel process for high efficient combined heat and power production from solid biomass. The processed air blown wood gasification in a pilot scale circulating fluidized bed was added by a catalytic tar reformer which would yield a tar-free gas quality suitable for IC-engine operation. Major efforts were taken for technical improvement of the tar reformer, especially concerning temperature control and cleaning devices which is important for keeping constantly a high activity. Pure natural timber did not yield chemical deactivation at the catalyst whereas the gasification of waste wood yielded decreasing activity which could be partly reversed by special measures taken. Further optimization of the process considered a better automation and improvement of the engine's flue gas emissions. Also a detailed economic consideration and evaluation of the entire process has been carried out. As a result the novel process should have economic advantages compared with conventional technology. (orig.) [German] Gegenstand des Vorhabens war die Weiterentwicklung eines Verfahrens zur effizienteren Strom- und Waermegewinnung aus festen Biobrennstoffen. Durch luftgeblasene Vergasung von Holz im Pilotmassstab in einer zirkulierenden Wirbelschicht und anschliessender katalytischer Teerspaltung konnte ein niederkalorisches Brenngas erzeugt werden, welches zum Betrieb eines Motoren-Blockheizkraftwerks geeignet war. Im Rahmen der Verfahrensoptimierung wurde der katalytische Teer-Reformer, insbesondere in Bezug auf Temperaturfuehrung und die zum Aktivitaetserhalt wichtige Abreinigungsvorrichtung, verbessert. Bei der Vergasung von Naturholz wurde keine chemische Desaktivierung festgestellt. Beim Altholzeinsatz wurde ein ueberwiegend reversibler Aktivitaetsverlust verzeichnet und begruendet. Geeignete Gegenmassnahmen wurden untersucht und beschrieben. Weitere Optimierungen betrafen die Anlagensteuerungstechnik im Hinblick auf die

Full Text Available Os resíduos vegetais na superfície do solo são muito efetivos em dissipar a energia de impacto das gotas de chuva, além de constituírem barreira física ao livre escoamento superficial da água. A presença desses resíduos em contato direto com a superfície do solo pode influenciar, decisivamente, a erosão em entressulcos. Este estudo objetivou avaliar as relações da erosão em entressulcos com a quantidade de resíduo vegetal em cobertura e verificar as diferenças nessas relações para palha de milho e palha de trigo. Um experimento de campo foi instalado no Centro de Pesquisa de Florestas e Conservação do Solo da FEPAGRO, em Santa Maria, RS, em Podzólico Vermelho-Escuro franco-arenoso. As parcelas experimentais mediam 0,50 x 0,75 m, com a maior dimensão no sentido do declive do terreno, que era de 0,17 m m-1, arranjadas em quatro blocos completos ao acaso. Palhas de milho e de trigo, picadas em fragmentos de 7,5 cm, foram distribuídas, nas parcelas, sobre solo recentemente preparado, em quantidades de 0,00, 0,05, 0,10, 0,20, 0,40 e 0,80 kg m-2. Em seguida, foi aplicada uma chuva simulada de intensidade média de 67 mm h-1 e duração de 90 min. As taxas de perdas de solo e água por erosão em entressulcos variaram ao longo da chuva, dependendo da quantidade de resíduo vegetal existente na superfície do solo, porém não foram observadas variações significativas em relação ao tipo de palha. A relação da erosão em entressulcos com a fração do solo coberto (dada em função da quantidade de palha pode ser expressa por meio de uma equação exponencial. Por ser um modelo simples, com medidas de fácil obtenção, sugere-se esse modelo para estimar o subfator cobertura do solo em entressulcos por resíduos em contato direto com a superfície.

This replication study investigated whether the {sup 137}caesium ({sup 137}Cs) contamination of wild boars could be relevantly reduced under field conditions by adding ammonium-iron-hexa-cyanoferrate (AFCF; Prussian blue) to the food. In 285 wild boars that had been shot in six Bavarian hunting territories during the season (November until May) between 01 November 2010 and 10 December 2011 {sup 137}Cs contamination was analysed. Thirty-five animals originated from two hunting territories in which offered food had been supplemented with 1250 mg AFCF per kilogram food. The control animals showed a mean {sup 137}Cs contamination of 522 Bq/kg lean skeletal muscle meat. Direct (univariable) comparisons of the two experimental territories with the four control territories yielded a mean reduction in {sup 137}Cs contamination due to Prussian bluefeeding by -211 Bq/kg (p < 0.001). Multivariable mo dels that took potential confounders into account (age, weight, sex, hunting date, territory) estimated the effect to be -344 Bq/kg (p < 0.05). This replication study confirmed the finding of Kienzle et al. (12) who described a statistically significant reduction in {sup 137}Cs contamination by -380 Bq/kg due to the feeding of Prussian blue in other territories.

We present relative elemental abundances for six elements (Mg, Al, Si, S, Ca, Fe) in the surface layer of 433 Eros, derived from a new analysis of the solar induced fluorescence measured by the NEARShoemaker X ray Spectrometer (XRS).XRS derived elemental abundances have been presented before. However, calibration of XRS data depends critically on knowledge of the incident solar spectrum, which varies greatly on time scales of seconds to minutes. Unfortunately, the gas solar monitor carried by NEAR was inadequately calibrated prior to launch. The previously published XRS results were based partly on broadband measurements by the Earthorbiting GOES8 (Geostationary Operational Environmental Satellites) Xray detectors and partly on a preliminary solar monitor calibration carried out by the present authors. The new solar monitor calibration is based on a more recent set of physical models of the solar spectrum at various temperatures, an improved fitting procedure, analysis of a large number of flight spectra, and comparison with concurrent data from the GOES Xray detectors. In addition, the new analysis includes data from three solar flares not considered in earlier papers.

Chuvas simuladas na intensidade de 64 mm h-1 e duração de 60 a 105 min foram aplicadas em quatro épocas: logo após a semeadura, 30 e 60 dias após a emergência e logo após a colheita do milho. A cobertura do solo propiciada pela cultura de inverno foi reduzida em 90% após o preparo convencional, independentemente da forma de tração. As perdas de solo e água medidas durante o desenvolvimento do milho foram sempre maiores sob preparo convencional do que sob plantio direto, independentemente da forma de tração, exceto logo após a colheita, quando a resteva estava uniformemente distribuída na superfície do solo. No preparo convencional, a erosão na cultura do milho foi, na média das formas de tração, 45% menor, quando antecedida de aveia preta no inverno do que quando antecedida de pousio descoberto. Por sua vez, a cultura do milho, por si só, reduziu a erosão em 60%, na média das formas de tração, comparada à do solo descoberto. A forma de tração influenciou a erosão somente no preparo convencional, com a animal apresentando perdas totais de solo 55 e 15% inferiores à tratorizada, respectivamente na cultura do milho e em solo descoberto. A perda de água por enxurrada foi mais afetada pela forma de tração no preparo convencional, totalizando, em média, 44% na animal e 57% na tratorizada, em relação ao volume total de chuva aplicado.

Full Text Available Accelerated soil erosion is, at present, one of the most widespread environmental problems in the world. Geographic Information Systems (GIS have become an essential tool in soil erosion studies and consequently in the development of appropriate soil conservation strategies. The objective of this paper was to assess the degree of soil erosion associated with land cover dynamics through GIS analysis and to validate the modeling with indicators of soil erosion. Universal Soil Loss Equation (USLE model, GIS technology and ground-truth dataset (erosion indicators were employed to elaborate the soil loss maps for four dates at Sorocaba Municipality (SP, Brazil. It was verified that, although the predicted soil loss rate is normally small along the study area, such rate is significantly greater than the soil formation rate. This shows a non-sustainable situation of soil and land cover management. Unplanned urban expansion seems be the main driving force that acts in increasing the erosion risk/occurrence along the study area.A erosão acelerada é um dos maiores problemas ambientais ocorrentes em larga escala na atualidade. Por sua vez, Sistemas de Informação Geográfica (SIG tornou-se uma ferramenta essencial em estudos de erosão e conseqüentemente no desenvolvimento de estratégias apropriadas para a conservação do solo. O objetivo deste trabalho foi avaliar o grau de erosão do solo associada com a dinâmica da cobertura do solo através de uma análise geoespacial e validar a modelagem com indicadores de erosão. Utilizou-se a Equação Universal de Perda de Solo (EUPS, recursos de SIG e dados de campo (indicadores de erosão para elaborar os mapas de perda de solo para quatro datas para o município de Sorocaba (SP, Brasil. Verificou-se que, embora a taxa de perda de solo ao longo da área de estudo é normalmente baixa, esta taxa é expressivamente maior que as taxas de formação do solo. Isto mostra uma situação não sustentável de

Full Text Available The constant increasing of eucalyptus forest areas in Brazil requires an accurate monitoring of water erosion. The present study aimed to evaluate soil, nutrients and organic carbon losses occasioned by water erosion in eucalyptus planted forests (EPF at different development stages (2, 3 and 7 years old. Soil erosion sediments were measured and sampled from standard erosion plots installed on Red Argisol-RA (Ultisol and Haplic Cambisol-HC (Inceptisol. Soil loss decreased as the age of plants increased; at the beginning of plant development, the canopy barely covered the soil surface, exposing the soil to higher erosion at young EPF plantations. Furrow planting system was used in the Red Argisol area and caused higher soil losses (1.1 to 6.2 Mg ha-1 year-1 as compared to pit planting system that was used in the Cambisol area (1.1 Mg ha-1 year-1. It is known that Cambisol is less resistant to erosion than Argisol. However, using pit system in this EPF, resulted in lower erosion and, therefore, nutrients and carbon losses than the traditional furrow system used in Argisol. Concerning the soil loss, this work points to the need of improving soil conservation practices to prevent soil erosion at the earlier stages of eucalyptus plantation. The amount of calcium and potassium were higher than magnesium in the soil sediment.The relatively high amount of carbon found in the erosion sediments raises additional concerns about the environmental sustainability and deserves future research.O aumento constante das áreas de florestas de eucalipto no Brasil impõe um monitoramento acurado da erosão hídrica.

Full Text Available En este artículo claramente divulgativo pretendemos recopilar unas cuantas menciones a Afrodita y Eros (junto con sus correspondientes nombres latinos, Venus y Cupido en la música de nuestro tiempo. Fijamos nuestra atención, más concretamente, en el género musical que se conoce con el nombre de rock, un género que nace en Norteamérica a finales de los años 50 como consecuencia de la fusión de otros muchos géneros musicales como el jazz, el country & western o el rhythm & blues. En un principio y por su misma naturaleza, las letras de rock eran poco profundas, basando toda su fuerza en el ritmo. Pero poco a poco, con la consolidación del género y su legitimación como música apta para cualquier público, los letristas buscaron argumentos en campos tan a priori alejados de la música popular de nuestro tiempo como puede ser la mitología clásica, con su acervo de imágenes, temas y personajes que han terminado convirtiéndose en recurrentes; y qué duda cabe de que en las canciones de tema amoroso –de las más comunes que aparecen en el rock-, Cupido y Venus junto con todos sus atributos afloran con bastante asiduidad.

Self-transcendence and Eros: The human condition between desire and the infinite

Directory of Open Access Journals (Sweden)

Cornel W. du Toit

2011-07-01

Full Text Available This article treats self-transcendence – like all transcendence – as a fact of human life. Inter alia this means that the human mind perforce operates in terms of binary concepts such as finitude–infinity, inner world–outside world, self–other, desire–fulfilment, separation–union and the like. We find these concepts in most myths of origin. The concept of desire (Eros, combining unfulfilment and the infinite, particularly epitomises self-transcendence. Ralph Waldo Emerson is cited as a precursor of the mid-19th century transcendentalists, whose ideas are resurfacing in present-day secular spirituality. In this article, we examined desire in the Christian conception of the Fall as envisioned by the Jewish philosopher Martin Buber and by Hegel, who integrates mind and nature in his philosophy of Spirit. The works of Emmanuel Levinas and Paul Ricoeur are used as points of reference to help us understand self and other in a framework of self-transcendence. The impact of these ideas on a postmetaphysical epistemology was also explored. Affectivity is a neglected area in Western thought and displays the same infinitude as rationality. The article concluded with present-day strategies of self-construction in a techno-scientific consumer culture.

Full Text Available A mudança no tipo de uso da terra, se não devidamente planejada e conduzida, poderá resultar em solos com capacidade produtiva diminuída e com propensão à erosão aumentada, o que irá diminuir o rendimento das culturas e prejudicar a conservação do solo e da água. Esta pesquisa teve como objetivo avaliar a erosão hídrica pluvial do solo em área originalmente de campo nativo, nos seus segundo e terceiro anos de cultivo com culturas anuais em fileira (respectivamente, feijão-miúdo - Vigna unguiculata - e sorgo - Sorghum bicolor, nos métodos de preparo do solo reduzido (escarificação e sem preparo (semeadura direta e nos tipos de adubação mineral (fertilizante NPK e orgânica (cama de aviário, além de uma condição sem adubação (tratamento testemunha. O estudo foi desenvolvido em campo, na EEA/UFRGS, em Eldorado do Sul (RS, nos verões de 2007/2008 e 2008/ 2009. Usou-se chuva simulada e um Argissolo Vermelho distrófico típico com textura franco-arenosa na camada superficial e declividade média de 0,13 m m- 1. Realizaram-se dois testes de erosão em cada ciclo cultural: o primeiro, logo após o preparo do solo e a semeadura das culturas; e o segundo, cerca de 90 dias mais tarde (estádio fenológico de enchimento de legumes, no caso do feijão-miúdo, e de maturação, no do sorgo. As chuvas foram aplicadas com o simulador de braços rotativos, na intensidade planejada de 64 mm h-1 e com duração de 1,5 h cada uma. Os resultados evidenciaram que a mudança no tipo de uso da terra, excluída a condição sem adubação, não ocasionou perdas relevantes de solo e água por erosão hídrica. A mobilização do solo pela escarificação, na maior parte dos casos, favoreceu a infiltração e a retenção superficial da água da chuva e, em decorrência, reduziu a enxurrada, ao mesmo tempo em que satisfatoriamente controlou a erosão. Por sua vez, a ausência de mobilização do solo na semeadura direta, também na maior parte

Full Text Available Perdas de nutrientes e matéria orgânica por erosão hídrica são fortemente influenciadas pelo manejo do solo. O uso de sistema de manejo inadequado pode causar poluição e eutroficação de mananciais, aumentar os custos com adubação e provocar a degradação de agroecossistemas. As perdas de cálcio, magnésio e potássio trocáveis e solúveis, fósforo disponível e matéria orgânica por erosão foram avaliadas, entre 1988 e 1994, em Latossolo Roxo álico epieutrófico muito argiloso, com 0,03 m m-1 de declividade, em Dourados (MS, sob condições de chuva natural, em diferentes sistemas de manejo do solo. Os tratamentos, aplicados na sucessão trigo-soja, foram: (a escarificação + gradagem niveladora, (b gradagem pesada + niveladora; (c plantio direto, e (d aração com arado de discos + duas gradagens niveladoras, sem cobertura vegetal. A enxurrada foi coletada diariamente e, em laboratório, separou-se o sobrenadante (solução do sedimento. O Ca2+, o Mg2+, o K+ e o P disponível foram determinados tanto na solução quanto no sedimento, e a matéria orgânica apenas no sedimento. Concentrações de Ca2+ e Mg2+ foram mais elevadas na solução, enquanto as de P e K+ foram maiores no sedimento. O plantio direto proporcionou a maior concentração média de P no sedimento entre os sistemas estudados; além disso, também resultou em maiores concentrações de Ca2+ em solução e taxa de enriquecimento em P no sedimento, em relação aos sistemas que envolveram preparo e cultivo de trigo-soja. Entretanto, o plantio direto foi o sistema mais eficaz no controle da erosão, perdendo as menores quantidades totais de nutrientes e de matéria orgânica. Dos sistemas que envolveram o cultivo da sucessão trigo-soja, o de gradagens (pesada + niveladora foi o menos eficaz, ficando o sistema de escarificação + gradagem niveladora em posição intermediária. Comparado ao plantio direto, o tratamento com gradagens perdeu cerca de 6,5 vezes

A study has been made of the influence of temperature of the second annealing that promotes formation of optically and electrically active centers o the erbium ion electroluminescence at lambda approx = 1.54 mu m wavelength in (111) Si : (Er,O) diodes. Doping has been performed by implantation of erbium and oxygen ions at 2.0, 1.6 MeV and 0.28, 0.22 MeV energies and 3 x 10 sup 1 sup 4 cm sup - sup 2 and 3 x 10 sup 1 sup 5 cm sup - sup 2 doses, respectively. The room temperature electroluminescence intensity under the breakdown regime increases with increasing annealing temperature from 700 to 950 deg C. After annealing in the range of 975-1100 deg C, erbium electroluminescence under the breakdown regime is not observed due to appearance of microplasmas. The injection electroluminescence intensity at 80 K decreases with increasing temperature from 700 to 1100 deg C

Es wird ein statistisches Modell zum Einfluß der thermischen Bewegung auf die NMR-Linienform vorgestellt, das die Verschmälerung von Festkörper-Spektren bei wachsender Temperatur beschreibt. Das Modell geht von der Annahme aus, daß nach einer Ortsveränderung eines Kerns infolge thermischer Bewegung jede beliebige Kernresonanzfrequenz mit der durch das Festkörperspektrum vorgegebenen Wahrscheinlichkeit angenommen werden kann. Am Beispiel der Festkörper-Gaußlinie wird der Unterschied zu dem bekannten Modell von ANDERSON und WEISS verdeutlicht.Translated AbstractA Statistical Model for the Influence of Thermal Motion on N. M. R. Spectra in SolidsA theory is proposed which allows to describe the narrowing of n. m. r.-line width in the presence of thermal motions of the spins. The model is based on the assumption, that the local resonance frequency of a given spin immediately after the jump is distributed according to the n. m. r.-line shape of the rigid lattice. The difference to the well-known ANDERSON-WEISS-model of spectral narrowing is demonstrated for a gaussian line shape.

Full Text Available A erosão entressulcos acontece pela desagregação originada do impacto das gotas de chuva e pelo transporte do escoamento superficial, por arraste e suspensão das partículas superficiais do solo desagregadas, onde se encontram a matéria orgânica e os nutrientes fundamentais para a produção agrícola. O trabalho objetivou avaliar o efeito de diferentes coberturas do solo em área de cultivo de cana-de-açúcar sob o escoamento superficial na erosão entressulcos. As condições avaliadas foram: solo descoberto; resíduo em contato direto com o solo; dossel da cana-de-açúcar e efeito somado do dossel da cana-de-açúcar e do resíduo em contato com o solo, para três e 12 meses após o corte da cana-planta. Os regimes de escoamento na erosão entressulcos foram laminar lento, e a erodibilidade para o Argissolo Vermelho-Amarelo foi de 1,87 x 10(6 kg s m-4, por conta da presença de mica e caulinita. O resíduo da cana em contato direto com o solo destacou-se no aumento da rugosidade hidráulica, e o dossel pela interceptação da chuva que retardou o início do escoamento superficial, possibilitando maiores taxas de infiltração de água no solo e menores taxas da erosão entressulcos.Interrill erosion occurs as a result of detachment of soil surface particles caused by raindrop impact and their transportation by overland flow (drag and suspension, which contain the organic matter and nutrients that are essential for agricultural production. An experiment was carried out to evaluate the effect of different soil cover types on the overland flow in interrill erosion in an area of sugarcane cultivation. The following situations were evaluated: bare soil; sugarcane straw mulch; sugarcane canopy cover; sugarcane canopy cover + sugarcane straw mulch three and 12 months after sugarcane harvest. The laminar flow regimes were slow and interrill soil erodibility of the Red-Yellow Argisol was 1.87 x 10(6 kg s m-4 due to the occurrence of kaolinite

Full Text Available Grande parte da costa noroeste de Portugal Continental compreende várias áreas em erosão acentuada, fato que tem vindo a contribuir para um agravamento da vulnerabilidade do território. Entendendo a faixa costeira uma área de interface entre os subsistemas terra-mar, constitui uma área dotada de grande mutabilidade, que se encontra em conflito com o atual cariz permanente da presença humana, pelo que a fragilidade tem a sua maior expressão na erosão e no recuo da linha de costa, fenómeno que tem vindo a resultar na perda de áreas de valor ecológico-ambiental e económico. Esta situação resulta de diversos fatores naturais que se relacionam com a subida do nível médio das águas do mar, mas também da atuação do homem sobre o território. A atuação antrópica nas áreas litorais nem sempre obedece a princípios de sustentabilidade ambiental e económica, fato explicado pela inexistência de uma estratégia bem definida de ordenamento do território. Apresentando-se como áreas de forte sensibilidade à ação antrópica, em especial relacionado com a pressão urbanística e, à implantação de infraestruturas relacionadas com o turismo e lazer, para além de estarem sujeitas a uma forte suscetibilidade de erosão provocada pelo avanço do mar, a forma de mitigação dos riscos seria a existência de planos de ordenamento que definissem uma estratégia de desenvolvimento não agressiva para as zonas de litoral em Portugal.

Foram utilizadas cartas de: solos, uso e ocupação das terras, redes de drenagem, declividade e dados pluviográficos, utilizando-se de um Sistema de Informação Geográfica (SIG -IDRISI. A espacialização do potencial de erosão só foi possível a partir da estimativa da tolerância às perdas laminares para cada tipo de solo da bacia, e da profundidade dos solos, por entender que as perdas são mais significativas em solos mais rasos do que em solos muito profundos. Na análise dos resultados, verificou-se que 37% da área total da bacia do Rio Uberaba (905,24 km² sofrem perdas de solos acima do limite de tolerância, sendo 12% em solos profundos e 25% em muito profundos, e a espacialização deste evento favorece a adoção de ações efetivas quanto à conservação dos solos da bacia.This work aimed to identify qualitatively the areas susceptive to laminar erosion in Uberaba river watershed, located in Uberaba-MG, Brazil, based on the mathematical model of the Universal Soil Loss Equation (USLE. The following maps had been used: soil, land use, drainage net, slope and rainfall data, using a Geographic Information System (GIS - IDRISI to analyze and manage the data that are linked to the location. The spatiality of the potential of erosion was possible from the estimative of the tolerance to laminar losses for each kind of soil in the watershed and soil depth, to understand that the losses are more significant in flatter soil than in very deep ones. In the analysis of the results, it was verified that 37% of the total area of the watershed of the Uberaba river (905,24 km² showed losses above the tolerance limit, being 12% in deep soil and 25% in very deeply ones, and the spatiality of this event, regards to

Full Text Available Este trabalho tem como objetivo principal o estudo e a análise da eficiência de dois diferentes tipos de recobrimentos usados na proteção contra o processo de desgaste por erosão em substratos fabricados em materiais compósitos poliméricos de uso aeronáutico, dando ênfase às peças fabricadas em fibras de vidro / kevlar impregnadas com resina epóxi. Revestimentos protetores baseados em um determinado tipo de tinta de poliuretano e um filme incolor de poliuretano foram utilizados para a avaliação da resistência à erosão, quando submetidos ao jateamento com microesferas de vidro. Para a realização dos ensaios de erosão foi projetado e construído um dispositivo específico para esse fim. Nos ensaios alguns fatores foram considerados, tais como: a natureza física das partículas abrasivas de microesferas de vidro, a distância, a velocidade e o ângulo de ataque das partículas durante o processo de jateamento. Os corpos-de-prova foram analisados quanto à sua variação de massa. Foram, também, utilizadas técnicas metalográficas na preparação de corpos-de-prova que foram analisados por microscopias óptica e eletrônica de varredura, assistida pela técnica de EDS, caracterizando o processo de erosão. Os resultados mostraram que os corpos-de-prova de compósitos poliméricos revestidos somente com a tinta de poliuretano apresentaram baixa resistência no ensaio de erosão. Entretanto, esta tinta quando protegida pelo filme incolor de poliuretano teve sua resistência à erosão aumentada na ordem de 5 vezes, aumentando, conseqüentemente, a vida útil do componente aeronáutico em sua aplicação final. Devido à facilidade de aplicação do filme de poliuretano no componente a ser protegido, os resultados deste estudo já estão sendo utilizados pelos fabricantes de aeronaves e operadores.The main goal of the present work is to evaluate the efficiency of two different coatings used as protection against the erosion wear

Full Text Available ResumoEm baixa encosta, a margem direita do rio das Pombas em Guarapuava (Paraná, foram identificados processos de erosão em túneis (pipes. Tratam-se de processos subsuperficiais de erosão que apresentam feições típicas, tais como, subsidência do teto do túnel e estruturas de abatimento, que tendem a evoluir para feições superficiais. Procurou-se com o presente trabalho reconhecer as propriedades físicas e químicas da encosta que apresenta o processo de erosão em túneis, com ênfase à textura, macroporosidade, densidade, porosidade e mineralogia de argilas. Foram realizadas análises granulométricas, de densidade aparente, real e porosidade total e análises químicas de difração de raios-X. Os resultados indicaram que o material que recobre o setor de baixa encosta, onde aparecem os túneis, apresenta textura arenosa devido às propriedades de microagregação gerada pelo argilomineral gibbsita, deixando o material com porosidade alta, favorecendo assim a circulação de água em subsuperfície. Os fluxos gerados tendem a ser exfiltrados para uma superfície de exposição, o que provoca a remoção de pequenas partículas de material (erosão por vazamento. Com a abertura de pequenos canais em subsuperfície, os fluxos tendem a se concentrar (escoamento por túnel e consequentemente ampliar os canais subsuperficiais pela ação mecânica da água. As características físicas e químicas encontradas na baixa encosta demonstram que a cobertura superficial é determinante para a instalação da erosão subsuperficial em túneis na área.AbstractIn lower hillslope, on the right bank of rio das Pombas, Paraná state, processes of tunnel erosion (pipes were identified. These are subsuperficial erosion processes with typical features, such as subsidence of the tunnel roof and rebate structures, which tend to evolve to superficial features.

Um único exemplar de cada fruta madura foi processado puro de modo a ser liquefeito e o pH foi medido utilizando-se um pH-metro, imediatamente e depois de 30 minutos. Posteriormente, a amostra de suco foi diluída em água na proporção de 1:2 e novas medidas foram tomadas. Para as bebidas industrializadas, as medidas de pH foram realizadas imediatamente após a abertura do frasco e depois de 30 minutos. As bebidas e sucos analisados mostraram valores abaixo do pH crítico de dissolução da estrutura dental, sugerindo a possibilidade de favorecerem a desmineralização. A orientação quanto à dieta ácida parece ser um fator importante no tratamento e prevenção das lesões de erosão dental.The aim of this paper was to evaluate the importance of the liquid diet pH in the etiology and prevention of dental erosion, so as to give dietary orientation to patients who present with these lesions, as well as to know the pH of the most consumed Brazilian fruit juices and industrialized beverages, which are supposably acid.

Entre elas encontram-se as falésias, que, por sua beleza, atraem a exploração turística o que, muitas vezes, compromete seu equilíbrio. Com a finalidade de proteger o meio ambiente das ações antrópicas, o poder público vem criando áreas para preservar e/ou conservar o meio ambiente, entre elas existem as APA e as APP. O objetivo do presente trabalho foi analisar a variabilidade espaço-temporal da linha de ruptura do relevo, na borda das falésias da APA Tambaba, entre os anos de 1985 e 2012; e identificar a existência de edificações dentro da APP no ano de 2012. Para tanto, foram utilizadas imagens do satélite Quickbird de 2012, do satélite IKONOS II de 2005 e fotos aéreas de 1985 para delimitação das linhas das falésias; o DSAS, que é uma extensão gratuita do ArcGIS, para obtenção de taxas de variação da linha de ruptura do relevo; e o software ArcGIS para delimitação e análise das APP. Como resultados, foram identificadas variações no movimento das linhas estudadas, tanto para erosão como para deposição nas falésias da APA Tambaba. No maior trecho da APA obteve-se uma média de -0,17m/ano para erosão e de 0,49m/ano para deposição, já no menor trecho a média de erosão foi -0,38m/ano e de deposição 0,14m/ano. Foi comprovada a existência de edificações irregulares correspondente a 22.818,91 m², o que equivale a aproximadamente 3% da área total da APP.

extreme soil degradation risk of the Ceveiro watershed in an integral and reliable form.Por definição, a tolerância de perda de terra por erosão deve considerar a preservação do solo como um recurso natural essencial para a produção das culturas. Taxas de erosão do solo superiores a sua renovação ocasionam diminuição da sua espessura. Uma espessura mínima foi definida como sendo a espessura abaixo da qual os insumos (fertilizantes, resíduos de culturas e a tecnologia de manejo (irrigação, culturas geneticamente melhoradas são insuficientes para manter economicamente a produtividade. Assim, taxas de erosão maiores do que a formação podem ser aceitas somente durante o tempo no qual não foi atingida a espessura mínima. Este período foi definido como tempo-de-vida. O conceito de tempo-de-vida foi aplicado na bacia do Ceveiro (1.945 ha, localizada em Piracicaba no sudeste do Brasil. O cálculo do tempo de vida foi realizado usando Sistema de Informações Geográficas. Para isto foram utilizadas estimativas das taxas de erosão pela Equação Universal de Perda de Solo e das profundidades do solo obtidas em levantamento de campo. Foram consideradas ainda uma taxa de formação de 0,2 mm ano-1, uma profundidade mínima do solo de 1,0m, e o cenário atual de uso da terra.

Os tratamentos com quatro repetições foram: com e sem cobertura de pastagem em quatro classes de declive: The water erosion is one of the main forms of soil degradation and it is highly affected by the soil cover and landscape slope. The objective of this work was to quantify the detachment rate and the soil loss due to water erosion under simulated rains in pastures, as well as to study the effect of land cover and the slope classes (< 9, 10-15, 25-30 and 35-40% on soil loss in the Ribeirão Salomea wathershed. The treatments with four repetitions were: with and without pasture covering in four slope classes: < 9, 10-15, 25-30 and 35-40%. Thirty-two simulated rains were applied in plots delimited by galvanized metallic foils fixed in the soil and having a gutter at their lower part for runoff sampling. The results showed that the land cover influenced soil loss only within each slope classes. Soil losses increased with increasing slope classes. This phenomenon was higher in uncovered land than in the covered ones. The erodibility was 1.48 x 105 kg s m-4 for the evaluated Mollisol.

The paragraph 2 of the German law on Environmental Impact Assessment (law on EIA) requires to determine, to record and to assess the effects which proposed major projects in the areas of industry, local government and transport have on man, animals, plants, soil, water, air, climate, landspace, assets and cultural heritage including the interactions between different media. For this purpose, bioindication is an effective tool. Up to now, the different methods of bioindication were not applied sufficiently although some of the methods have already been standardised in guidelines (VDI, DIN). Users and authorities might feel insecure which bioindication method should be applied when assessing the impacts of a given project. This paper gives recommendations which bioindication method should be applied for the different major projects listed in the law on EIA. A widespread set of data obtained by the use of bioindicators is necessary to meet the demands of paragraph 2. (orig.)

In this study, input variables for chemical transport models were compared from different meteorological drivers each with other and with the measured friction velocities in one place. Friction velocities are used as a measure of the mechanical turbulence, but are made available neither by numerical weather models nor routinely available observations: so they must either recalculate or estimated. In this study, friction velocities (u{sup *}), which is measured for years by the DWD in Lindenberg near Berlin, averaged over 30 minutes and have been made available to FU Berlin, compared with modeled values. The considered models are firstly the diagnostic interpolation model TRAMPER, on the other the prognostic models of the DWD COSMO-EU and the EZMWF. The boundary layer relevant parameters from the NWM were recalculated from the involved groups, which has been made for the COSMO-EU the one from the FU Berlin, the other from IfT in Leipzig. The boundary layer variables in the EZMWF model, however, were determined by TNO Netherlands. The measurements have shown that u{sup *} in the forest twice as high as above the meadow.

Based on a comparison of the discussion in German and French print media, she illustrates (in Foucauldian terms how a discoursive controversy on PGD happens. The study impresses with its clearly structured empirical section, which draws a geological map of the PGD-discourse. This also underlines the current pertinence of the term biopower.

Full Text Available No contexto semi-árido do Nordeste do Brasil os processos superficiais são comandados pela magnitude dos inputs pluviais, sua recorrência espaço-temporal e interação direta com as formações superficiais peculiares a este domínio e as práticas de uso da terra. De fato, na escala das micro-bacias a erosão hídrica representa a forma mais importante de ocorrência e constitui um problema ambiental nos espaços agrários tradicionais do semi-árido nordestino. Na bacia do riacho Mulungu, o panorama social da comunidade denota o baixo nível de desenvolvimento humano, enquanto o panorama ambiental reflete a pressão que esta exerce sobre o seu suporte natural, sendo observada erosão linear em sulcos e ravinas, formação de leques de dejeção assoreando o leito do rio, crostas salinas na superfície do solo e baixa densidade da cobertura vegetal nativa. O objetivo deste trabalho foi determinar um índice de vulnerabilidade à erosão para a bacia do riacho Mulungu, utilizando os princípios da Ecodinâmica de Tricart e técnicas de sistema de informção geográfica e sensoriamento remoto. A fim de se obter uma imagem sucinta da estruturação superficial da paisagem e sua dinâmica, foram superpostos em ambiente digital os mapas pedológico, geomorfológico, geológico, de vegetação, do modelo digital de elevação e de declividade da área. Em seguida, foram estimados índices de vulnerabilidade considerando a interação entre a geologia, a geomorfologia, os tipos de solo, a vegetação, a distribuição da precipitação e o uso do solo. A partir da análise desses parâmetros, foi estimado um índice geral de vulnerabilidade morfodinâmica para a bacia que correspondeu a 2,0, indicando que a área da bacia possui um grau de susceptibilidade intermediário.

After the relatively broad program of experimental activities, which have been involved in the complex R and D program for the Molten Salt Reactor (MSR) - SPHINX (SPent Hot fuel Incinerator by Neutron fluX) concept development in the Czech Republic, there has been a next stage (namely large-scale experimental verification of design inputs by use of MSR-type inserted zones into the existing light water moderated experimental reactor LR-0 called EROS project) started, which will be focused to the experimental verification of the rector physical or neutronic properties of other types of reactor concepts applying molten salts in the role of liquid fuel and/or coolant. This tendency is based on the recently accepted decision of the MSR SSC of GIF to consider for further period of its activity two baseline concepts- fast neutron molten salt reactor non-moderated (FMSR-NM) as a long-term alternative to solid fuelled fast neutron reactors and simultaneously, advanced high temperature reactor (AHTR) with pebble bed type solid fuel cooled by liquid salts. There will be a brief description of the prepared and performed experimental programs in these directions (as well as the preliminary results obtained so far) introduced in the paper. (author)

The use of natural soils for low-cost removal of precipitated water and slightly polluted waste water has become an issue in legal procedures concerning water management. Although groundwater protection is given high priority, authorities do not have sufficient data on long-term effects and decomposition effects during passage to the soil.

The investigation is the first in a series of which the following effects are expected: Faster results by preliminary assessment of the applicability of the technique envisaged, use of this low-cost technology for waste water treatment in consideration of surface water protection.

Research on the processing of sexual stimuli has proved that such material has high priority in human cognition. Yet, although sex differences in response to sexual stimuli were extensively discussed in the literature, sexual orientation was given relatively little consideration, and material suitable for relevant research is difficult to come by. With this in mind, we present a collection of 200 erotic images, accompanied by their self-report ratings of emotional valence and arousal by homo- and heterosexual males and females (n = 80, divided into four equal-sized subsamples). The collection complements the Nencki Affective Picture System (NAPS) and is intended to be used as stimulus material in experimental research. The erotic images are divided into five categories, depending on their content: opposite-sex couple (50), male couple (50), female couple (50), male (25) and female (25). Additional 100 control images from the NAPS depicting people in a non-erotic context were also used in the study. We showed that recipient sex and sexual orientation strongly influenced the evaluation of erotic content. Thus, comparisons of valence and arousal ratings in different subject groups will help researchers select stimuli set for the purpose of various experimental designs. To facilitate the use of the dataset, we provide an on-line tool, which allows the user to browse the images interactively and select proper stimuli on the basis of several parameters. The NAPS ERO image collection together with the data are available to the scientific community for non-commercial use at http://naps.nencki.gov.pl.

ERO and PIC simulations of gross and net erosion of tungsten in the outer strike-point region of ASDEX Upgrade

Full Text Available We have modelled net and gross erosion of W in low-density l-mode plasmas in the low-field side strike point region of ASDEX Upgrade by ERO and Particle-in-Cell (PIC simulations. The observed net-erosion peak at the strike point was mainly due to the light impurities present in the plasma while the noticeable net-deposition regions surrounding the erosion maximum could be attributed to the strong E ×B drift and the magnetic field bringing eroded particles from a distance of several meters towards the private flux region. Our results also imply that the role of cross-field diffusion is very small in the studied plasmas. The simulations indicate net/gross erosion ratio of 0.2–0.6, which is in line with the literature data and what was determined spectroscopically. The deviations from the estimates extracted from post-exposure ion-beam-analysis data (∼0.6–0.7 are most likely due to the measured re-deposition patterns showing the outcomes of multiple erosion-deposition cycles.

According to recent studies, the risk for thyroid cancer is not increased after radioiodine treatment in patients with hyperthyroidism. Only the risk of cancer of the stomach seems to be increased slightly in patents treated with I-131 because of functional autonomy. However, the risk for gastric cancer is not increased after higher activities of I-131 because of thyroid cancer. There is no increased risk for genetic abnormalities after radioiodine treatment of hyperthyroidism. (orig.) [Deutsch] Aktuelle Studien zum Karzinomrisiko nach Radioiodtherapie wegen Hyperthyreose ergeben keinen Anhalt fuer eine erhoehte Inzidenz des Schilddruesenkarzinoms nach therapeutischer Gabe von I-131. Allenfalls scheint die Inzidenz von Magenkarzinomen bei Patienten nach Radioiodtherapie wegen funktioneller Autonomie geringfuegig erhoeht zu sein, obwohl diese Beobachtung bei Patienten nach hochdosierter Radioiodtherapie wegen eines Schilddruesenkarzinoms nicht gemacht wurde. Hinweise fuer ein erhoehtes genetisches Risiko nach Radioiodtherapie der Hyperthyreose ergeben sich nicht. (orig.)

Full Text Available Water erosion is the major cause of soil and water losses and the main factor of degradation of agricultural areas. The objective of this work was to quantify pluvial water erosion from an untilled soil with crop rows along the contour, in 2009 and 2010, on a Humic Dystrupept, with the following treatments: a maize monoculture; b soybean monoculture; c common bean monoculture; d intercropped maize and bean, exposed to four simulated rainfall tests of on hour at controlled intensity (64 mm h-1. The first test was applied 18 days after sowing and the others; 39, 75 and 120 days after the first test. The crop type influenced soil loss through water erosion in the simulated rainfall tests 3 and 4; soybean was most effective in erosion control in test 3, however, in test 4, maize was more effective. Water loss was influenced by the crop type in test 3 only, where maize and soybean were equally effective, with less runoff than from the other crops. The soil loss rate varied during the runoff sampling period in different ways, demonstrating a positive linear relationship between soil and water loss, in the different rainfall tests.A erosão hídrica é a principal causa das perdas de solo e água, assim como de degradação das áreas agrícolas.

Cambisols, Luvisols, and Regosols are the dominant soils in the watershed. Oak tree Mediterranean woodland, Agricultural crops and pastures are the major land uses. Soil erosion risks were assessed by estimating soil loss by water erosion with the PESERA model. Land area at risk of desertification was determined based on the MEDALUS methodology. Based on meteorological data from the period 2001-2006, the three most representative classes of soil loss by water erosion were: <0.5 t/ha/year in 32.1% of the area; 5-10 t/ha/year in 23.3% of the area; and 10-20 t/ha/year in 16.9% of the area. Considering the same time period, the land area at risk of desertification was classified: 1.8% as none threatened; 3.9% as potential; 68.4% as fragile; and 25.9% as critical to desertification.

Full Text Available The theme of the dream of the beloved, object of special interest by the Spanish studies (Palley 1983; Maurier 1990, Alatorre 2003, links Iberian poets of the Siglo de Oro to Italian Petrarchist poetry, often through direct textual subsidiaries, both at a level of inventio and elocutio. The purpose of this study is to examine some cases in which the Petrarchist poetry, between Italy and Spain, expresses the dialectic between the desire for the real but coy and unattainable woman, and his dream ghost, more complacent and comforting. This research particularly focuses on the relationship between Eros and memory of the beloved woman body, the concept of the dream as deception, new for the Renaissance. Moreover, it would be pointed out a special cases of imitatio between Tasso and Góngora, in which the dream becomes maker of substitutive image of the beloved. Through a comparative analysis of some texts, the study highlights the constant and the variations with which Petrarchist poetry presents the theme of the dream ghost of beloved. Attention has been paid to the differences with the Petrarch RVF, as well as to the manner of reinventing and reinterpreting the theme of the maestros italianos by Spanish Petrarchism.

Por ser a pesquisa de erosão comumente cara e morosa, a utilização de modelos permite estimar a perda de solo em localidades e condições não diretamente representadas nos estudos. O objetivo deste trabalho foi estimar a expectativa de erosão do solo em uma área intensivamente cultivada com cana-de-açúcar no município de Piracicaba (SP, como subsídio ao diagnóstico do uso atual das terras visando ao controle do processo. O trabalho foi realizado em ambiente de sistema de informação geográfica aplicando a equação universal de perda de solo (EUPS. Especificamente pretendeu-se estudar a influência dos fatores K (erodibilidade do solo, LS (topográfico, C (uso e manejo da cultura e P (práticas de controle da erosão nas estimativas de perda de solo.

The work reported was to investigate the changes caused at the crack tip of a specimen with incipient crack and to assess their effects with regard to component fracture. The steels selected for testing are the pressure vessel steels 10MnMoNi5-5 and 17MoV8-4, and the experiments were made with CT-25 specimens. The conclusion drawn from the results obtained is that the WPS effect is due to a stronger energy dissipation in the prestressed area ahead of the crack tip, assisted by intrinsic stress-induced crack closing.

Neste trabalho foi aplicada a EUPS para indentificar qualitativamente  áreas susceptíveis a erosão laminar na região do Alto Parnaíba (PI-MA. Em termos específicos foram utilizadas diferentes metodologias para os cálculos dos fatores R (Krigeagem e IDW e LS(mapa de área de contribuição pelos métodos D8 e D", com a utilização de SIG, visando identificar as que melhor se aplicam a grandes áreas, e somado a estes dois fatores, foi aplicado um fator de correção em áreas com grades com resolução espacial superiores á 100 m. Assim, mapas temáticos existentes, juntamente com informações de solos, uso da terra, relevo e clima, foram utilizados para obtenção de mapas identificando áreas susceptíveis á erosão atual e potencial nesta região. Chegou-se á conclusão que a metodologia que melhor se aplica ao cálculo do fator R (erosividade foi a que utiliza Krigeagem Ordinária, e para o fator LS, a metodologia que utiliza mapa de área de contribuição obtida pelo método D". As áreas mais críticas, com relação a perdas de solos estão associadas a elevadas declividades, NEOSSOLOS e uso e manejo inadequados. A metodologia se mostrou válida, uma vez que os pontos onde se encontram os maiores índices de perdas de solo foram comparados a pontos observados in loco, mostrando boa correlação com as estimativas obtidas.

There are two different types of fuel cells for small-scale applications, li.e. polymer electrolyte membrane fuel cells (PEMFC) and high-termperature fuel cells with ceramic solid electrolytes (SOFC). Both types of fuel cells have different advantages and shortcomings. One of the main problems, however, is the fact that research is still going on and that commercial fuel cell systems for space HVAC applications are still not available. (orig.) [Deutsch] Nach dem heutigen Stand werden zwei unterschiedliche Brennstoffzellen-Typen zum Einsatz in Kleinanlagen entwickelt.

The Euratom directive 2013/59 (''EU directive for radiation protection'') has to be implemented into national law by spring 2018 and requires a complete recording of patient dosages and relevant parameters. Additionally, a medical physics expert has to be consulted for each radiological examination above a defined threshold. A complete recording of the dosage administered from all modalities and optimization of the radiological procedures should result in a reduction of the total dosage. This can be achieved by automated systems that incorporate not only the detection of the dose parameters but also the evaluation and analysis of these data. When provided with warning levels such a system should be able to inform or warn the operator when dose thresholds have been exceeded or even better inform the operator about possible excess dosages before an examination. Depending on the information provided by the modality, dose management systems can operate at different levels in the picture archiving and communication system (PACS), radiological and hospital information systems (RIS/HIS) or with the header information of a digital imaging and communications in medicine (DICOM) image and evaluate and analyze this data. A practicable use of such systems is only possible by close cooperation of medical personnel, medical physicists and information technology (IT) administrators. Various systems are available commercially or free but an individual adaptation of these systems is useful and necessary, depending on the requirements of the radiology practice or hospital. (orig.)

The formation of disulfide bonds in the endoplasmic reticulum (ER) of eukaryotic cells is catalyzed by the sulfhydryl oxidase, ER oxidoreductin 1 (Ero1), and protein-disulfide isomerase (PDI). PDI is oxidized by Ero1 to continuously introduce disulfides into substrates, and feedback regulates Ero1 activity by manipulating the regulatory disulfides of Ero1. In this study we find that yeast Ero1p is enzymatically active even with its regulatory disulfides intact, and further activation of Ero1p by reduction of the regulatory disulfides requires the reduction of non-catalytic Cys90-Cys97 disulfide in Pdi1p. The principal client-binding site in the Pdi1p b′ domain is necessary not only for the functional Ero1p-Pdi1p disulfide relay but also for the activation of Ero1p. We also demonstrate by complementary activation assays that the regulatory disulfides in Ero1p are much more stable than those in human Ero1α. These new findings on yeast Ero1p-Pdi1p interplay reveal significant differences from our previously identified mode of human Ero1α-PDI interplay and provide insights into the evolution of the eukaryotic oxidative protein folding pathway.

Processos erosivos são responsáveis pela degradação desses recursos, em várias partes do globo. Objetivou-se, com este estudo, avaliar a dinâmica da cobertura da terra em uma região de topografia complexa e empregar a equação universal de perda de solos modificada (RUSLE para quantificar a perda de solos em decorrência da erosão. O uso da terra no distrito de Vale Vêneto, município de São João do Polêsine na região central do Estado do Rio Grande do Sul, foi avaliado em imagens Landsat nos anos de 1988, 2000 e 2007. A análise espaço temporal do uso da terra indica que as áreas de floresta tiveram um aumento de 16,2% no período de 19 anos. As áreas de agricultura sofreram uma diminuição de 57,5%, no mesmo período. A erosão bruta específica sofreu uma redução de 44%, de 1988 a 2007. Verificou-se que a desintensificação do uso da terra leva a uma configuração mais favorável de conservação do solo e mitigação da erosão. É provável que as mudanças ocorridas no uso da terra estejam relacionadas à não reprodução das famílias rurais que, anteriormente, cultivavam áreas impróprias para a atividade agrícola nesta região.Conservation of natural resources such as soil and water should be a concern of governments and institutions.

Strains of bacteria were investigated with a view to their applicability and efficiency in enhanced recovery of petroleum. The mechanisms of enhanced recovery with bacteria were to be clarified as well. The experiments were carried out as static autoclave experiments without bedrock and as dynamic flooding experiments in a model pore space (Bentheim sandstone and carbonate rock) under the conditions of North German petroleum deposits. The static experiments carried out preliminary to the more time-consuming dynamic flooding experiments were to help with an optimized design of the injection experiments. (orig.) [Deutsch] Die vorliegende Arbeit hat zum Ziel, entoelungswirksame Bakterienstaemme zu untersuchen und hinsichtlich der durch sie bewirkten Erhoehung des Entoelungsgrades zu bewerten. Gleichzeitig sollen die Mechanismen aufgeklaert werden, die der Entoelungsverbesserung durch Einsatz von Bakterien zugrunde liegen. Die Experimente wurden als statische Autoklavenversuche ohne Lagerstaettengestein sowie als dynamische Flutversuche im Modellporenraum (Bentheimer Sandstein und karbonatisches Gesteinsmaterial) unter Bedingungen norddeutscher Lagerstaetten durchgefuehrt. Die statischen Versuche, die als Auswahltests den aufwendigeren dynamischen Flutversuchen vorgeschaltet waren, sollten dazu beitragen, die Flutversuche gezielt konzipieren zu koennen. (orig./EF)

A long-term study on natural attenuation and remediation in soil and groundwater at the former military base Schaeferhof-Sued (Niedersachsen) was performed at a former gasoline filling station. At this locality, a large residual source of benzene, toluene, ethylbenzene, xylenes (BTEX) and additional petroleum hydrocarbons is present in the soil. BTEX-concentrations in the groundwater and their correlation with groundwater level variations were monitored for three years. Within the monitoring period, a very dry summer was recorded, which caused the groundwater level to drop by 1.7 m and the BTEX concentrations to increase from 240 {mu}g/l to 1300 {mu}g/l at the site of contamination. The microbial degradation of BTEX was documented by data on consumption of electron acceptors (oxygen, nitrate or sulphate) and production of reduced products (Fe(II), methane). The degradation is further supported by the detection of metabolites. Therefore, the increasing BTEX concentrations were not a consequence of limited biological degradation. (orig.)

Full Text Available A study was taken in a 1566 ha watershed situated in the Capivara River basin, municipality of Botucatu, São Paulo State, Brazil. This environment is fragile and can be subjected to different forms of negative impacts, among them soil erosion by water. The main objective of the research was to develop a methodology for the assessment of soil erosion fragility at the various different watershed positions, using the geographic information system ILWIS version 3.3 for Windows. An impact model was created to generate the soil's erosion fragility plan, based on four indicators of fragility to water erosion: land use and cover, slope, percentage of soil fine sand and accumulated water flow. Thematic plans were generated in a geographic information system (GIS environment. First, all the variables, except land use and cover, were described by continuous numerical plans in a raster structure.The land use and cover plan was also represented by numerical values associated with the weights attributed to each class, starting from a pairwise comparison matrix and using the analytical hierarchy process. A final field check was done to record evidence of erosive processes in the areas indicated as presenting the highest levels of fragility, i.e., sites with steep slopes, high percentage of soil fine sand, tendency to accumulate surface water flow, and sites of pastureland. The methodology used in the environmental problems diagnosis of the study area can be employed at places with similar relief, soil and climatic conditions.A área de estudo, com 1566 ha, abrange uma microbacia hidrográfica, posicionada em local de relevo em contato reverso-frente de cuesta-depressão periférica paulista, inclusa na Bacia do Rio Capivara, no município de Botucatu, Estado de São Paulo.

Unraveling the cellular response to oxidative stress in the endoplasmic reticulum

Hansen, Henning Gram

, disulfide bonds are predominantly generated by the two isoforms of the ER oxidoreductin-1 (Ero1) family: Ero1α and Ero1β. Both enzymes oxidize the active-site cysteines in protein disulfide isomerases (PDIs), which in turn introduce disulfide bonds into newly synthesized proteins. Ero1 is re......-oxidized by molecular oxygen and this step generates hydrogen peroxide: a reactive oxygen species. Intramolecular disulfide bonds tightly regulate the oxidase activity of Ero1α. Whereas the regulatory mechanisms that regulate Ero1α activity are well understood, the overall cellular response to oxidative stress....... Interestingly, depletion of GPx8 in cells induced expression of an antioxidant response marker only in the presence of Ero1. These findings imply that GPx8 is an important scavenger of Ero1-generated hydrogen peroxide, and thus provides a critical function in negotiating oxidative stress originating from...

Search for brown dwarfs by gravitational microlensing effect with the pixels method. Analysis of AGAPE and EROS collaborations data

1995-01-01

This work is involved in baryonic dark matter search in galactic halos. An important collect of observational data has been initiated to test the hypothesis that this dark mass is made of compact objects such as brown dwarfs or small mass stars. The gravitational microlensing effect allows to probe this distribution of this mass type along the line of sight of nearby galaxies such as the Large Magellanic Cloud. A new way to detect these microlensing events has been proposed by P. Baillon et al.: the pixel method. The aim is to detect the amplification of stars which are unresolved or too faint to be seen by classical analysis. First, we present this method and the simulations which allow to establish its feasibility. Then, we describe the pixel analysis of the 91-92 EROS data on the Large Magellanic Cloud. The selection of luminosity variations with a shape compatible with microlensing events allows us to study the sensitivity of this analysis. We see how these results allow us to validate the pixel method applied on a large volume of data. This also shows the possibility to find luminosity variations which escape classical analysis research. Strengthened by these results, we finally describe the analysis of the AGAPE 94 data on the Andromeda galaxy which uses the same pixel method. Being ten times farther away than the Large Magellanic Cloud, the Andromeda galaxy has very few resolved stars, making the pixel method the only way of looking for microlensing events. (author) [fr

A recent paper by asserts that the ERoEI (also referred to as EROI) of photovoltaic (PV) systems is so low that they actually act as net energy sinks, rather than delivering energy to society. Such claim, if accurate, would call into question many energy investment decisions. In the same paper, a comparison is also drawn between PV and nuclear electricity. We have carefully analysed this paper, and found methodological inconsistencies and calculation errors that, in combination, render its conclusions not scientifically sound. Ferroni and Hopkirk adopt ‘extended’ boundaries for their analysis of PV without acknowledging that such choice of boundaries makes their results incompatible with those for all other technologies that have been analysed using more conventional boundaries, including nuclear energy with which the authors engage in multiple inconsistent comparisons. In addition, they use out-dated information, make invalid assumptions on PV specifications and other key parameters, and conduct calculation errors, including double counting. We herein provide revised EROI calculations for PV electricity in Switzerland, adopting both conventional and ‘extended’ system boundaries, to contrast with their results, which points to an order-of-magnitude underestimate of the EROI of PV in Switzerland by Ferroni and Hopkirk. - Highlights: • A recent paper by Ferroni and Hopkirk estimated an EROI=0.8 for PV in Switzerland. • We identify several critical methodological and calculation flaws in that paper. • We discuss such flaws in detail and rebut Ferroni and Hopkirk's conclusions. • We provide revised EROI calculations with both conventional and extended boundaries.

After optimization of the cooler design and positioning, the new vehicle was able to meet the specifications while the first of the two vehicles only achieved 35 km/h without overheating of the cooling system. Finally, a theoretical investigation identified the measures that should be taken to achieve sufficient cooling in countries with hot climates, e.g. the USA. It was found that it would be sufficient to raise the coolant temperature from 90 C to about 110 C to ensure good performance in these climate zones. (orig.)

ERO-TEXTOR. 3D-Monte Carlo code for local impurity-modeling in the scrape-off-layer of TEXTOR. Version 2.0

International Nuclear Information System (INIS)

Koegler, U.; Winter, J.

1997-03-01

The ERO-TEXTOR code is described in detail. The code solves the kinetic equations of impurities in the scrape-off layer of a tokamak plasma in the vicinity of material surfaces like limiters or divertors. A relaxation time ansatz in the traced impurity limit is chosen, taking the gyro-motion of the particles into account. Since the background plasma is slightly non-maxwellian at the plasma edge higher order corrections (thermal forces) to the relaxation time ansatz are also considered. Background plasma parameters are calculated from a simple plasma model, i.e. the one dimensional continuity and momentum equations are used to derive the local electron density, the local flow velocity and the pre-sheath and sheath electric fields. Since these calculations are not done in a selfconsistent way, the measured values of electron density and temperature are used as basic input to derive the dependency of these quantities. The regarded magnetic topology is still straight and uniform. Also detailed account is given to the plasma surface interaction and the erosion/deposition processes. A linear differential equation model for multi species impact on a material surface has been developed and is used in a discrete time step approximation. External databases include the ionization rates for atomic species, molecular processes of methane and silane molecules and the sputtering and reflection yields, which are taken from binary collision calculation codes (e.g. TRIM) or from semi-empirical fits (e.g. the Bodhansky and Yamamura fits).

Full Text Available A erosão do solo é a principal causa do empobrecimento precoce de terras produtivas e dentre as suas formas está a erosão laminar. Esta se caracteriza não apenas pela remoção de uma camada relativamente uniforme da superfície, mas também por seus nutrientes, sendo intensificada, portanto, pelas ações antrópicas. Para evitar ou reduzir seus impactos, fazem-se necessárias diretrizes para a adequação do uso e da ocupação às condições de cobertura vegetal, tipo de solo e topografia, através de mapas do potencial erosivo laminar da região de interesse, obtidos via sistemas de informações geográficas (SIG. Neste trabalho foi desenvolvido o mapeamento do potencial erosivo laminar da bacia do rio Japaratuba, SE (1685 km²; trata-se de uma região sujeita a intensa atividade agrícola, pecuária e de mineração, onde só restam 6% da vegetação nativa. Os resultados mostram que 48,71% da área da bacia ficam nas classes de médio e alto potencial erosivo, indicando que a bacia está bastante impactada devido aos usos inadequados para as condições de solo e declividades.Soil erosion is a natural phenomenon that reduces soil fertility and causes a great impact on agricultural areas. Laminar erosion is characterized by the removal of the top soil fairly uniformly as well as its nutrients, which is accelerated by human activities. To minimize the impacts it is necessary to adopt an adequate soil management that takes into account the type of the soil, relief, and vegetation cover. The soil management can be aided by mapping the erosive potential of a region using GIS tools. In this work, the technique that was used for mapping the erosive potential in the Japaratuba River Basin (1685 km² located in the State of Sergipe is presented. The results show that 48.71% of the basin area lie within medium and high erosive potentials zones, suggesting the inadequate land use for the soil types and relief within the basin.

This study investigated characteristics of recombinant wheat Endoplasmic Reticulum Oxidoreductin 1 (wEro1) and its influence on Chinese steamed bread (CSB) qualities. The purified wEro1 monomer, which contained two conserved redox active motif sites, bound to flavin adenine dinucleotide (FAD) cofactor with a molecular weight of ∼47 kDa. wEro1 catalyzed the reduction of both bound and free FAD, and its reduction activity of free FAD reached 7.8 U/mg. Moreover, wEro1 catalyzed the oxidation of dithiothreitol and wheat protein disulfide isomerase (wPDI). Both glutathione and the reduced ribonuclease could work as electron donors for wEro1 in catalyzing the oxidation of wPDI. Additionally, wEro1 supplementation improved the CSB qualities with an increased specific volume of CSB and decreased crumb hardness, which was attributed to water-insoluble wheat proteins increasing and gluten network strengthening. The results give an understanding of the properties and function of wEro1 to facilitate its application especially in the flour-processing industry. Copyright © 2018 Elsevier Ltd.

Mating in the Closest Living Relatives of Animals Is Induced by a Bacterial Chondroitinase.

Science.gov (United States)

Woznica, Arielle; Gerdt, Joseph P; Hulett, Ryan E; Clardy, Jon; King, Nicole

2017-09-07

We serendipitously discovered that the marine bacterium Vibrio fischeri induces sexual reproduction in one of the closest living relatives of animals, the choanoflagellate Salpingoeca rosetta. Although bacteria influence everything from nutrition and metabolism to cell biology and development in eukaryotes, bacterial regulation of eukaryotic mating was unexpected. Here, we show that a single V. fischeri protein, the previously uncharacterized EroS, fully recapitulates the aphrodisiac-like activity of live V. fischeri. EroS is a chondroitin lyase; although its substrate, chondroitin sulfate, was previously thought to be an animal synapomorphy, we demonstrate that S. rosetta produces chondroitin sulfate and thus extend the ancestry of this important glycosaminoglycan to the premetazoan era. Finally, we show that V. fischeri, purified EroS, and other bacterial chondroitin lyases induce S. rosetta mating at environmentally relevant concentrations, suggesting that bacteria likely regulate choanoflagellate mating in nature.

Full Text Available A erosão hídrica é a forma mais séria de degradação do solo, pois, além de reduzir a capacidade produtiva deste para as culturas, causa prejuízos financeiros e ambientais em razão da perda de nutrientes a ela associada. A presente pesquisa foi realizada com o objetivo de quantificar as perdas de água e solo, de P, K, Ca e Mg na água e de P disponível e K, Ca e Mg trocáveis nos sedimentos da enxurrada perdida por erosão hídrica, em um experimento realizado sob chuva natural, entre novembro de 1992 e outubro de 2003, no sul do Planalto Catarinense. Calculou-se o custo financeiro desses nutrientes, expressos na forma de superfosfato triplo (P, cloreto de potássio (K e de calcário (Ca e Mg, perdidos na erosão hídrica, para um Cambissolo Húmico alumínico léptico com declividade média de 0,10 m m-1, em três sistemas de manejo do solo, com duas repetições: preparo convencional (PC, preparo mínimo (PM e semeadura direta (SD. Em uma das repetições dos tratamentos foram cultivados soja, trigo, milho, ervilhaca, feijão, aveia, soja e nabo forrageiro, em sistema de rotação de culturas, enquanto na outra se cultivaram soja, trigo, soja, trigo, soja, trigo, soja e trigo, em sistema de sucessão de culturas. Para efeito de realização deste trabalho, as duas parcelas experimentais com o mesmo tipo de manejo do solo foram consideradas como repetição, embora com diferentes espécies culturais (em rotação e em sucessão de culturas. As perdas de solo foram fortemente influenciadas pelo sistema de manejo e variaram com os anos de cultivo, enquanto as perdas de água variaram menos do que as de solo, tanto nos sistemas de manejo do solo quanto nos anos de cultivo. O valor monetário das perdas anuais de P expresso na forma de superfosfato triplo, de K expresso como cloreto de potássio e de Ca e Mg expressos na forma de calcário, por erosão hídrica, foi relativamente elevado, independentemente do sistema de manejo do solo.

Full Text Available O preparo do solo, o qual influencia o manejo dos resíduos culturais e a rugosidade superficial, associado ao tipo de cultura utilizada, é um dos fatores que afetam a suscetibilidade do solo à erosão hídrica. Utilizando chuvas simuladas na intensidade constante de 64 mm h-1, com durações suficientes para que o escoamento superficial atingisse taxa constante de descarga, foram avaliados, em Eldorado do Sul (RS, de 1992 a 1994, em condições de campo, os seguintes tratamentos de preparo do solo: semeadura direta, na presença e na ausência dos resíduos recém-colhidos de milho e trigo; escarificação, na presença e na ausência dos resíduos recém-colhidos de milho e trigo + milho logo após a colheita do trigo; e aração + gradagem, na presença e ausência dos resíduos recém-colhidos de milho e trigo + milho logo após a colheita do trigo. Utilizou-se um solo podzólico vermelho-amarelo franco-arenoso e declividade média de 0,066 m m-1. As perdas de solo e água foram fortemente influenciadas pela rugosidade e cobertura superficiais. Na semeadura direta e aração + gradagem, a manutenção dos resíduos culturais na superfície reduziu as perdas de solo em relação à sua remoção manual quase completa. A semeadura direta com os resíduos culturais foi o tratamento mais eficaz na redução da erosão e a aração + gradagem, sem os resíduos, o menos eficaz. A escarificação com os resíduos culturais na superfície apresentou maior perda de solo do que a semeadura direta e aração + gradagem também com os resíduos na superfície. Em geral, as perdas de água por escoamento superficial seguiram o mesmo comportamento das perdas de solo.

Precise and Fast Computation of the Gravitational Field of a General Finite Body and Its Application to the Gravitational Study of Asteroid Eros

International Nuclear Information System (INIS)

Fukushima, Toshio

2017-01-01

In order to obtain the gravitational field of a general finite body inside its Brillouin sphere, we developed a new method to compute the field accurately. First, the body is assumed to consist of some layers in a certain spherical polar coordinate system and the volume mass density of each layer is expanded as a Maclaurin series of the radial coordinate. Second, the line integral with respect to the radial coordinate is analytically evaluated in a closed form. Third, the resulting surface integrals are numerically integrated by the split quadrature method using the double exponential rule. Finally, the associated gravitational acceleration vector is obtained by numerically differentiating the numerically integrated potential. Numerical experiments confirmed that the new method is capable of computing the gravitational field independently of the location of the evaluation point, namely whether inside, on the surface of, or outside the body. It can also provide sufficiently precise field values, say of 14–15 digits for the potential and of 9–10 digits for the acceleration. Furthermore, its computational efficiency is better than that of the polyhedron approximation. This is because the computational error of the new method decreases much faster than that of the polyhedron models when the number of required transcendental function calls increases. As an application, we obtained the gravitational field of 433 Eros from its shape model expressed as the 24 × 24 spherical harmonic expansion by assuming homogeneity of the object.

Classical destructive test methods are fixed part of industrial sectors for decades such as aerospace, automotive, railway and power plants. A high degree of standardization of procedures, and training in form of an ISO standard are present, but not in non-destructive testing of civil engineering (ZfPBau). Except for the rebound hammer NDT methods in civil engineering are not standardized. Also of personnel qualifications can be found in regulations very few requirements, although it is obvious that this is an indispensable prerequisite for the proper application of the procedures and reliable inspection results. In this contribution experiences with a presented training concept in which the construction inspector will trained to DIN 1076 in a two-day course. Here are the necessary conditions worked out, such as the creation of suitable test bodies or the definition of necessary course content for establishing training courses. [German] Klassische zerstoerungsfreie Pruefverfahren sind seit Jahrzehnten fester Bestandteil industrieller Bereiche wie Luftfahrt, Automotive, Eisenbahn und Kraftwerke. Ein hoher Normungsgrad der Verfahren und Ausbildungsstandards in Form einer ISO-Norm liegen vor. Bei der zerstoerungsfreien Pruefung im Bauwesen (ZfPBau) ist das anders. Bis auf den Rueckprallhammer sind ZfPBau-Verfahren nicht genormt. Auch zur Personalqualifikation finden sich in Regelwerken nur sehr wenige Anforderungen, obwohl es offensichtlich ist, dass dies eine unverzichtbare Voraussetzung fuer die richtige Anwendung der Verfahren und zuverlaessige Pruefaussagen ist. In diesem Beitrag werden Erfahrungen mit einem Ausbildungskonzept vorgestellt, bei dem Bauwerkspruefer nach DIN 1076 in einem zweitaegigen Lehrgang ausgebildet werden. Dabei werden die notwendigen Voraussetzungen heraus gearbeitet, wie z.B. die Erstellung von geeigneten Testkoerpern oder die Festlegung notwendiger Kursinhalte, die zum Etablieren von Ausbildungskursen erforderlich sind.

This report, which relates the situation as of July 1997, again confirms the internationally leading role of the Federal German Republic in the phase-out of CFCs. No country has realised a more comprehensive concept for the phase-out of substances that deplete the ozone layer. Combining statutory and voluntary measures has proved a path-breaking approach. One of the most important driving forces in the CFC phase-out were the restrictions of use imposed by the Ordinance on the Prohibition of CFCs and Halon.

Access for endovascular repair of abdominal aortic aneurysms (EVAR) is obtained through surgical cutdown or percutaneously. The only devices suitable for percutaneous closure of the 20 French arteriotomies of the common femoral artery (CFA) are the Prostar(™) and Proglide(™) devices (Abbott Vascular). Positive effects of these devices seem to consist of a lower infection rate, and shorter operation time and hospital stay. This conclusion was published in previous reports comparing techniques in patients in two different groups (cohort or randomized). Access techniques were never compared in one and the same patient; this research simplifies comparison because patient characteristics will be similar in both groups. Percutaneous access of the CFA is compared to surgical cutdown in a single patient; in EVAR surgery, access is necessary in both groins in each patient. Randomization is performed on the introduction site of the larger main device of the endoprosthesis. The contralateral device of the endoprosthesis is smaller. When we use this type of randomization, both groups will contain a similar number of main and contralateral devices. Preoperative nose cultures and perineal cultures are obtained, to compare colonization with postoperative wound cultures (in case of a surgical site infection). Furthermore, patient comfort will be considered, using VAS-scores (Visual analog scale). Punch biopsies of the groin will be harvested to retrospectively compare skin of patients who suffered a surgical site infection (SSI) to patients who did not have an SSI. The PiERO trial is a multicenter randomized controlled clinical trial designed to show the consequences of using percutaneous access in EVAR surgery and focuses on the occurrence of surgical site infections.

Eros and politics

Directory of Open Access Journals (Sweden)

Helge Rønning

2015-02-01

Full Text Available There are many parallels between Henrik Ibsen’s Rosmersholm (1886 and Bjørnstjerne Bjørnson’s Paul Lange og Tora Parsberg (1898. Both dramas have as their protagonist a weak and noble man, who is offered love and an erotic relationship by a strong woman, and who is not able to reciprocate.              At the same time they are plays about how politics demand the ability to act and take a stand in a world where men are supposed to engage politically at the same time as women are supposed to stand in the background. In both dramas the political and the erotic are interwoven in a manner that drives the men into despair because they can neither satisfy the demands of love in the intimate arena nor the demands for power in the public arena of politics.             There are also other parallels between the plays, in relation to the role of the figures, that demand of the protagonists that they take a stand, and drop them and betray them when they do not. Both dramas also end in a final suicide. Though here the two plays differ in that in Ibsen’s play the drama ends in the double suicide of the man and the woman, while in Bjørnson’s it is only the man who sacrifices himself. This implies that the question of strength, power and the erotic are more consistently played out in Ibsen’s drama.

Full Text Available It is a commonplace the almost non-existent Spanish contribution to erotic literature. This matter has to do, at the same time, with the consideration on what is regarded as "pornographic". However, it is necessary to consider here how far pornography implies the subject who decides to see something as such. Archaeology, on the other hand, has been giving evidences of the changes produced in ancient iconography's reception; and has come, by this way, to enlighten the consideration of the erotic in Spain itself, where the taboo imposed on sexuality by the ecclesiastical power has limited the erotic to a massive and trivial consume.

Countertransference and the erotic.

Science.gov (United States)

Ulanov, Ann Belford

2009-03-01

Eros is like a huge spark that ignites our passion and then confronts us with the problem of living out this fire in ordinary space and time. What do we each know of this spark, this flame? Who or what was it's object? Where have we felt this force for unity in ourselves, with another person, with life itself? Where are we unlived erotically? Where are the chinks in our erotic life? In focusing on the erotic in clinical work, we usually begin with the analysand's transference. I want to explore eros in the life of the analyst for our relation to eros influences the clinical work we do. When eros is constellated, two possibilities of relationship present themselves: to an actual other who must be reckoned with as real, and to a psychic content, equally real, which we do not invent or control. How do we experience this electricity? What is our desire like? What does it take us back to, and toward what unseen purpose does it propel us? Eros brings with it a sense of purpose, of going somewhere important, something that enlists body, soul, and spirit.

Full Text Available Der vorliegende Aufsatz behandelt am Beispiel des Deutschen und des brasilianischen Portugiesisch den Prozeß der Grammatikalisierung als ein umfassendes Modell für erosive Vorgänge in der Geschichte natürlicher Sprachen. Grammatikalisierung wird vorgestellt als Abbau der pragmatischen Vielseitigkeit, semantischen Konkretheit, syntaktischen Freiheit und phonetischen Substanz von Sprachelementen. Ihr Gesamtgebiet wird zerlegt in den Prozeß der Lexikalisierung, der polylexematische Elemente in monolexematische überführt, und den der Delexikalisierung, der lexematische Elemente zu sublexmatischen reduziert. Im Mittelpunkt dieser Vorgänge seht das Lexikon, das als der zentrale Elementvorrat der Sprache gesehen wird. Auch innerhalb des Lexikons setzt sich der Prozeß der Grammatikalisierung fort, von den lexikalischen Wortklassen über die Übergangsklassen zu den grammatischen Klassen. Die untere Grenze des Lexikons stellt eine kritische Schwelle dar, bis zu der dem Prozeß der Grammatikalisierung das sprachliche Recycling gegenübersteht, durch das lexematische Elemente über die Bildung neuer polylexematischer Einheiten in den Kreislauf zurückfließen. Unterhalb dieser Schwelle jedoch ist kein Recycling mehr möglich, so daß Elemente, die einmal den lexematischen Charakter verloren haben, auf die Dauer zum Verschwinden verurteilt sind. Die verschiedenen Etappen der Grammatikalisierung werden anhand konkreter Beispiele, zunächst aus dem brasilianichen Portugiesisch, anschließend aus dem Deutschen, vorgestellt und illustriert.

The U.S. Air Force (USAF) has tasked the Pacific Northwest Laboratory (PNL) in support of the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP), to identify, evaluate, and assist in acquiring all cost-effective energy projects at Cape Canaveral Air Force Station (AFS). Projects considered can be either in the form of energy management or energy conservation. The overall efforts of this task are based on a model program PNL is designing to support energy-use decisions in the federal sector. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at Cape Canaveral AFS, which is located approximately 10 miles north of Cocoa Beach, Florida. It is a companion report to Volume 1: Executive Summary and Volume 2: Baseline Detail. The results of the analyses of EROs are presented in 11 common energy end-use categories (e.g., boilers and furnaces, service hot water, and building lighting). A narrative description of each ERO is provided, including information on the installed cost, energy and dollar savings, impacts on operations and maintenance (O&M), and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. Descriptions of the evaluation methodologies and technical and cost assumptions are also provided for each ERO. Summary tables present the cost- effectiveness of energy end-use equipment before and after the implementation of each ERO and present the results of the life-cycle cost (LCC) analysis, indicating the net present value (NPV) and savings-to-investment ratio (SIR) of each ERO.

Acute low-level alcohol consumption reduces phase locking of event-related oscillations in rodents.

Event-related oscillations (EROs) are rhythmic changes that are evoked by a sensory and/or cognitive stimulus that can influence the dynamics of the EEG. EROs are defined by the decomposition of the EEG signal into magnitude (energy) and phase information and can be elicited in both humans and animals. EROs have been linked to several relevant genes associated with ethanol dependence phenotypes in humans and are altered in selectively bred alcohol-preferring rats. However, pharmacological studies are only beginning to emerge investigating the impact low intoxicating doses of ethanol can have on event-related neural oscillations. The main goal of this study was to investigate the effects of low levels of voluntary consumption of ethanol, in rats, on phase locking of EROs in order to give further insight into the acute intoxicating effects of ethanol on the brain. To this end, we allow rats to self-administer unsweetened 20% ethanol over 15 intermittent sessions. This method results in a stable low-dose consumption of ethanol. Using an auditory event-related potential "oddball" paradigm, we investigated the effects of alcohol on the phase variability of EROs from electrodes implanted into the frontal cortex, dorsal hippocampus, and amygdala. We found that intermittent ethanol self-administration was sufficient to produce a significant reduction in overall intraregional synchrony across all targeted regions. These data suggest that phase locking of EROs within brain regions known to be impacted by alcohol may represent a sensitive biomarker of low levels of alcohol intoxication.

In Germany, persons who are to be exposed to radiation for medical research purposes are protected by a licensing requirement. However, there are considerable uncertainties on the part of the applicants as to whether licensing by the competent Federal Office for Radiation Protection is necessary, and regarding the choice of application procedure. The article provides explanatory notes and practical assistance for applicants and an outlook on the forthcoming new regulations concerning the law on radiation protection of persons in the field of medical research. Questions and typical mistakes in the application process were identified and evaluated. The qualified physicians involved in a study are responsible for deciding whether a license is required for the intended application of radiation. The decision can be guided by answering the key question whether the study participants would undergo the same exposures regarding type and extent if they had not taken part in the study. When physicians are still unsure about their decision, they can seek the advisory service provided by the professional medical societies. Certain groups of people are particularly protected through the prohibition or restriction of radiation exposure. A simplified licensing procedure is used for a proportion of diagnostic procedures involving radiation when all related requirements are met; otherwise, the regular licensing procedure should be used. The new radiation protection law, which will enter into force on the 31st of december 2018, provides a notification procedure in addition to deadlines for both the notification and the licensing procedures. In the article, the authors consider how eligible studies involving applications of radiation that are legally not admissible at present may be feasible in the future, while still ensuring a high protection level for study participants.

Diferentes sistemas de preparo podem melhorar as condições do solo, evitar problemas de erosão e diminuir custos de implantação. Em áreas de propriedade da TANAGRO S.A e da SETA S.A., nos municípios de Piratini e Butiá, RS, em dois tipos de solos distintos - Neossolo Litólico e Argissolo Vermelho-Amarelo, foram testados sistemas de preparo do solo com diferentes níveis de movimentação para plantio de acácia-negra: plantio de mudas em covas e plantio após subsolagens com duas, três e cinco hastes e uso de gradagens. Foram avaliados o crescimento em DAP e altura, anualmente, e produção de biomassa aérea no corte raso. Os solos foram caracterizados química e fisicamente em seus horizontes superficiais. Nas plantas, após sete anos, foram coletadas amostras de discos em seis posições no tronco para avaliação das densidades básicas. Preparo do solo com subsolador de cinco hastes apresentou maiores perdas de solo, que foram mensuráveis apenas até 18 meses após o plantio. Essas perdas de solo são extremamente importantes na sustentabilidade da produção do Neossolo Litólico, composto em 80% de calhaus e cascalho. O preparo reduzido do solo, com a abertura de covas manual e mecanicamente para plantio da acácia negra, não diminuiu o crescimento das plantas em ambos os solos estudados. No entanto, o desenvolvimento inicial das plantas de acácia negra, plantadas em sistema de preparo reduzido, foi mais lento (altura e DAP, defasagem que permaneceu até os 24 meses após o plantio.

The US Air Mobility Command (AMC) has tasked Pacific Northwest Laboratory (PNL) with supporting the US Department of Energy (DOE) Federal Energy Management Program`s (FEMP) mission to identify, evaluate, and assist in acquiring all cost-effective energy resource opportunities (EROs) at the David Grant Medical Center (DGMC). This report describes the methodology used to identify and evaluate the EROs at DGMC, provides a life-cycle cost (LCC) analysis for each ERO, and prioritizes any life-cycle cost-effective EROs based on their net present value (NPV), value index (VI), and savings to investment ratio (SIR or ROI). Analysis results are presented for 17 EROs that involve energy use in the areas of lighting, fan and pump motors, boiler operation, infiltration, electric load peak reduction and cogeneration, electric rate structures, and natural gas supply. Typical current energy consumption is approximately 22,900 MWh of electricity (78,300 MBtu), 87,600 kcf of natural gas (90,300 MBtu), and 8,300 gal of fuel oil (1,200 MBtu). A summary of the savings potential by energy-use category of all independent cost-effective EROs is shown in a table. This table includes the first cost, yearly energy consumption savings, and NPV for each energy-use category. The net dollar savings and NPV values as derived by the life-cycle cost analysis are based on the 1992 federal discount rate of 4.6%. The implementation of all EROs could result in a yearly electricity savings of more than 6,000 MWh or 26% of current yearly electricity consumption. More than 15 MW of billable load (total billed by the utility for a 12-month period) or more than 34% of current billed demand could also be saved. Corresponding natural gas savings would be 1,050 kcf (just over 1% of current consumption). Total yearly net energy cost savings for all options would be greater than $343,340. This value does not include any operations and maintenance (O&M) savings.

Many experimental and theoretical results lead to the conclusion that at least 80 percent of the mass of our Galaxy is dark. Part of this so-called dark matter could be in the form of stellar mass compact objects, called MACHOS; these could be detected using the gravitational microlensing effect. The first generation experiments EROS1 and MACHO have strongly constrained the galactic abundance of objects lighter than 0.01 solar mass to less than 10 percent of the total mass. In parallel, the observation by the MACHO group of massive candidates (half the Sun's mass), numerous enough to constitute 50 percent of galactic dark matter, was a further motivation for the EROS group to extend this search to stellar mass objects in a second phase, EROS2. The present work deals with the analysis of 25 million stellar light curves in the Large Magellanic Cloud, observed for three years in order to extract the rare microlensing candidates and to measure the galactic halo mass fraction in the form of compact objects. After recalling the motivations of this search and the theoretical context, I describe the EROS2 experiment. The observational strategy and the photometric reduction procedures needed to deal with the 1.2 To of data are then presented. A new method to detect micro-lenses is detailed, as well as a discussion of background light curves, poorly known. We do not find enough microlensing candidates to explain the galactic rotation curve; this confirms, and improve on previous EROS1 and EROS2 results. Combining all results from EROS allows to exclude that MACHOS with a mass between 10 e-7 and 10 solar mass are important constituents of the galactic halo. This statement agrees with recent results from the MACHO group, although our interpretations differ, namely on the topics of the location of the lenses, and of a possible contamination of the microlensing ample by background phenomena.

Mild Cognitive Impairment (MCI) is considered in many as prodromal stage of Alzheimer's disease (AD). Event-related oscillations (ERO) reflect cognitive responses of brain whereas sensory-evoked oscillations (SEO) inform about sensory responses. For this study, we compared visual SEO and ERO responses in MCI to explore brain dynamics (BACKGROUND). Forty-three patients with MCI (mean age=74.0 year) and 41 age- and education-matched healthy-elderly controls (HC) (mean age=71.1 year) participated in the study. The maximum peak-to-peak amplitudes for each subject's averaged delta response (0.5-3.0 Hz) were measured from two conditions (simple visual stimulation and classical visual oddball paradigm target stimulation) (METHOD). Overall, amplitudes of target ERO responses were higher than SEO amplitudes. The preferential location for maximum amplitude values was frontal lobe for ERO and occipital lobe for SEO. The ANOVA for delta responses showed significant results for the group Xparadigm. Post-hoc tests indicated that (1) the difference between groups were significant for target delta responses, but not for SEO, (2) ERO elicited higher responses for HC than MCI patients, and (3) females had higher target ERO than males and this difference was pronounced in the control group (RESULTS). Overall, cognitive responses display almost double the amplitudes of sensory responses over frontal regions. The topography of oscillatory responses differs depending on stimuli: visualsensory responses are highest over occipitals and -cognitive responses over frontal regions. A group effect is observed in MCI indicating that visual sensory and cognitive circuits behave differently indicating preserved visual sensory responses, but decreased cognitive responses (CONCLUSION).

The US Air Force Air Combat Command (ACC) has tasked the US Department of Energy (DOE) Federal Energy Management Program (FEMP) to identify, evaluate, and assist in acquiring all cost-effective energy projects at Griffiss Air Force Base (AFB). FEMP, with support from the Pacific Northwest Laboratory (PNL), is designing this model program for federal customers served by the Niagara Mohawk Power Company. The program with Griffiss AFB will (1) identify and evaluate all cost-effective electric energy projects; (2) develop a schedule for project acquisition considering project type, size, timing, capital requirements, as well as energy and dollar savings; and (3) secure 100% of the financing required to implement electric energy efficiency projects from Niagara Mohawk and have them procure the necessary contractors to perform detailed audits and install the technologies. This report provides the results of the electric energy resource opportunity (ERO) assessments performed by PNL at one of Niagara Mohawk`s primary federal facilities, the ACC Griffiss AFB facility located near Rome, New York. The results of the analyses of EROs are presented in seven common energy end-use categories. A narrative description of each ERO provides information on the initial cost, energy and dollar savings; impacts on operations and maintenance (O&M); and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. The evaluation methodology and technical and cost assumptions are also described for each ERO. Summary tables present the operational performance of energy end-use equipment before and after the implementation of each ERO and the results of the life-cycle cost analysis indicating the net present value (NPV) and savings-to-investment ratio (SIR) of each ERO.

Full Text Available Conventional forms of African American activism and organization in the second half of the twentieth century have been the subject of academic research for quite some time, but less attention has been devoted to symbolic and body political forms of intervention. Looking at the Afro hairstyle and hip hop culture, this article explores how African American identity has been reflected through Style Politics. It outlines the history of African American hairstyles from the 1970s until the 2000s and identifies elements of popular culture such as Blaxploitation movies and rap music as constitutive of African American fashion. The question of ›respectability‹ that surfaced in the context of racist discourses about black women will be examined through the example of First Lady Michelle Obama, who rose to fame as a fashion icon. In conclusion, the article discusses the case of Trayvon Martin, an African American teenager who was killed in 2012 while wearing a hoodie, making the garment once again an object of contention and a symbol of protest. * * * Klassische Formen des Aktivismus und der Organisierung von African Americans in der zweiten Hälfte des 20.

This survey covers the potential use of neurophysiological changes as a biomarker in four neuropsychiatric diseases (attention deficit hyperactivity disorder (ADHD), Alzheimer's disease (AD), bipolar disorder (BD), and schizophrenia (SZ)). Great developments have been made in the search of biomarkers in these disorders, especially in AD. Nevertheless, there is a tremendous need to develop an efficient, low-cost, potentially portable, non-invasive biomarker in the diagnosis, course, or treatment of the above-mentioned disorders. Electrophysiological methods would provide a tool that would reflect functional brain dynamic changes within milliseconds and also may be used as an ensemble of biomarkers that is greatly needed in the evaluation of cognitive changes seen in these disorders. The strategies for measuring cognitive changes include spontaneous electroencephalography (EEG), sensory evoked oscillation (SEO), and event-related oscillations (ERO). Further selective connectivity deficit in sensory or cognitive networks is reflected by coherence measurements. Possible candidate biomarkers discussed in an interactive panel can be summarized as follows: for ADHD: (a) elevation of delta and theta, (b) diminished alpha and beta responses in spontaneous EEG; for SZ: (a) decrease of ERO gamma responses, (b) decreased ERO in all other frequency ranges, (c) invariant ERO gamma response in relation to working memory demand; for euthymic BD: (a) decreased event-related gamma coherence, (b) decreased alpha in ERO and in spontaneous EEG; for manic BD: (a) lower alpha and higher beta in ERO, (b) decreased event-related gamma coherence, (c) lower alpha and beta in ERO after valproate; and for AD: (a) decreased alpha and beta, and increased theta and delta in spontaneous EEG, (b) hyperexcitability of motor cortices as shown by transcortical magnetic stimulation, (c) hyperexcitability of visual sensory cortex as indicated by increased SEO theta responses, (d) lower delta ERO, (e

Full Text Available In den letzten Jahrzehnten ist die Fachsprache zu einem der wichtigsten Gegenstände der angewandten Linguistik geworden. In der lituanistischen Sprachwissenschaft wird aber dieser Begriff noch selten erwähnt und ist noch kaum definiert. Mehrere diesen Begriff bezeichnende Termini („dalykinë kalba“, „specialioji kalba“, „specialybës kalba“ ir „profesinë kalba“ werden verwendet, deren Inhalt aber nicht genau festgelegt wird. In der germanistischen Fachsprachenforschung wird der Begriff „Fachsprache“ mit Hilfe lexikalischer, grammatischer, kommunikativ-funktionaler, soziolinguistischer, pragmatischer, kognitiver, soziologischer Kriterien beschrieben. Die Fachsprache als Gegenstand der Linguistik ist heterogen. Mehrere Klassifizierungsmodelle der Fachsprache stellen die Komplexität und die Vielfalt der Gliederungskriterien dieses Gegenstands dar. Die meist verwendeten Kriterien sind das Fach und der Abstraktionsgrad der Sprache. Die Fixierung der Fachbereiche führt zu horizontaler Gliederung der Fachsprache. Unter Fächern und ihren Fachsprachen werden z.B. Wirtschaft, Geschichte, Biologie, Medizin, Literaturwissenschaft verstanden. Die horizontal gegliederten Fachsprachen werden vertikal geschichtet. Die vertikale Schichtung einer Fachsprache erfolgt aufgrund ihres Spezialisierungs- und Abstraktionsgrads.Der Forschungsgegenstand hat sich mit der Geschichte der Sprachwissenschaft vom Fachwort zur fachsprachlichen Syntax geändert. In der letzten Zeit steht im Mittelpunkt der Fachsprachenforschung der Fachtext, die Fachtextsorten sowie die Fachkommunikation als Hauptgegenstand der Fachsprachenforschung.Aufgrund der Vielfalt der Kommunikationsbereiche und Kommunikationspartner, zu denen auch z. B. Laien gehören, könnte die litauische Benennung „dalykinë kalba“ den oben dargestellten Begriff am genausten bezeichnen.

Full Text Available The aim of this article is to expose a dichotomy between the inter- and intrapersonal aspects of sexuality that haunt the current discourse on sexual normality. This division has led to a dual movement: in one direction to a moral relativism and in the other to an exclusive focus on sexual instincts. Thus, in the current discourse on sexuality, the interpersonal dimension o f sexuality is underplayed, while the intrapersonal dimension is overemphasized. I argue instead for a bridging of the gap between the inter- and intrapersonal dimensions of sexuality. The reason: neither moral relativism nor a rigid deterministic structure for sexual instincts represents an adequate view of, on the one hand the description of sexuality, and on the other the prescription o f the expression of that sexuality. In conclusion, I point to a few consequenses o f the integration o f both dimensions for sexual normality.

The US Air Force Space Command (SPACECOM) has tasked the Pacific Northwest Laboratory (PNL), as the lead laboratory supporting the US Department of Energy (DOE) Federal Energy Management Program (FEMP), to identify, evaluate, and assist in acquiring all cost-effective energy projects at Vandenberg Air Force Base (VAFB). This is part of a model program that PNL is designing to support energy-use decisions in the federal sector. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at the SPACECOM VAFB facility located approximately 50 miles northwest of Santa Barbara, California. It is a companion report to Volume 1, Executive Summary, and Volume 2, Baseline Detail. The results of the analysis of EROs are presented in ten common energy end-use categories (e.g., boilers and furnaces, service hot water, and building lighting). In addition, a case study of process loads at Space Launch Complex-4 (SLC-4) is included. A narrative description of each ERO is provided, including information on the installed cost, energy and dollar savings; impacts on operation and maintenance (O and M); and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. A description of the evaluation methodologies and technical and cost assumptions is also provided for each ERO. Summary tables present the cost-effectiveness of energy end-use equipment before and after the implementation of each ERO and present the results of the life-cycle cost (LCC) analysis indicating the net present value (NPV) and value index (VI) of each ERO. Finally, an appendix includes a summary of an economic analysis case study of the South Vandenberg Power Plant (SVPP) operating scenarios.

Quantificação de erosão em sistemas agroflorais e convencionais na Zona da Mata de Minas Gerais Evaluation of erosion under agroforestry and conventional systems in Zona de Mata de Minas Gerais

Directory of Open Access Journals (Sweden)

Fernando Silveira Franco

2002-11-01

Full Text Available A Zona da Mata de Minas Gerais é caracterizada por topografia forte ondulada, com solos intemperizados com baixa fertilidade natural e regime pluviométrico capaz de sustentar uma vegetação florestal. A ocupação da terra é minifundiária, predominando a agricultura familiar, que sofre as conseqüências da modernização da agricultura, exigindo uso intensivo do solo, o que, conseqüentemente, promove perdas de solo, água e nutrientes por erosão. Uma das alternativas propostas para redução das perdas por processos erosivos foi a implantação de sistemas agroflorestais. O objetivo deste estudo foi comparar as perdas por erosão em sistemas agroflorestais implantados em propriedades de pequenos agricultores com as perdas em sistemas convencionais. Os sistemas foram implantados como unidades experimentais de observação das condições socioambientais dos agricultores, utilizando metodologias participativas. Estas unidades experimentais apresentam dificuldades para quantificação da erosão, quando são usadas metodologias convencionais. A dinâmica do manejo utilizado pelos agricultores dificulta o uso de métodos que exigem a implantação de equipamentos permanentes. Além disto, os métodos que exigem o isolamento das parcelas produzem efeitos de borda que mascaram os resultados, quando comparados com os do sistema aberto conduzido por agricultores. Desta forma, foi desenvolvido um coletor de água e solo para superar tais limitações. O equipamento é composto por uma "mesa", que é inserida no solo, acoplada a uma calha móvel que sustenta um saco plástico. A água e o solo coletados no saco plástico são quantificados e analisados. Foram instalados coletores em 25 unidades de observação, sendo 14 em sistemas convencionais e 11 em sistemas agroflorestais. A energia dos eventos erosivos foi calculada a partir de pluviogramas, para estimar as perdas potenciais anuais dos sistemas. Os dados foram coletados na estação chuvosa

Full Text Available O potencial de erosão de uma chuva, representado pelo produto da energia cinética pela intensidade máxima em 30 minutos, foi calculado para chuvas individuais, para Campinas (SP. Durante um período de 22 anos (de 1954 a 1975, o índice de erosão médio anual computado foi de 6.738 MJ.mm/ha.h.ano, tendo os valores variado de 3.444 a 13.830. Foram estabelecidas as distribuições mensais e estacionais do índice de erosão. Os dados mostraram que 62% do potencial de erosão anual ocorre durante dezembro-fevereiro. A freqüência de distribuição dos valores totais anuais e do valor máximo anual do índice de erosão seguiu o tipo de curva inclinada, típica de dados hidrológicos, mas o logaritmo dos dados apresentou distribuição normal. Foi encontrada alta correlação entre a média mensal do índice de erosão e a média mensal do coeficiente de chuva, o que simplifica o método para calcular o índice de erosão de um local.The rainfall erosion potential for individual storms was evaluated for Campinas, State of São Paulo, Brazil. The erosion potential of a rainstorm is the product of the rainfall energy and the maximum 30-minute intensity of the storm. Over a 22-year period the average annual erosion index computed was 6,738 MJ.mm/.ha.h.year (values ranged from 3,444 to 13,830. Monthly and seasonal distributions of the erosion index were established. The data showed that 62% of the annual erosion potential occurs during the period from December to February. The frequency distribution of the total annual and maximum annual individual storm erosion index was skewed, but the logarithms of the data appeared to be normally distributed. Expected average monthly and annual values of erosion potential may be readily estimated from local rainfall amount records by the equation EI = 68,730 (p²/P0,841. A high correlation was found between actual and estimated EI values.

Directory of Open Access Journals (Sweden)

Ralf Binswanger

2016-07-01

Full Text Available Fritz Morgenthaler steht mit seinem Konzept der «Weichenstellungen » auf dem Boden von Freuds Postulat, wonach homosexuelle und heterosexuelle Orientierungen gleich erklärungsbedürftig sind. Allerdings können die «Weichenstellungen» weniger Hetero- oder Homosexualität per se erklären, sondern eher die verschiedenen Formen von Homo- und Heterosexualität in actu, wie sie in Fantasie und Verhalten gelebt werden. Mit Sexualität per se und Sexualität in actu sind zwei qualitativ verschiedene Gesichtspunkte benannt, unter denen Diskurse über manifeste und organisierte Sexualität sowie Perversionen mit Vorteil geführt werden. Dabei wird der Perversionsbegriff ausschliesslich der Sexualität in actu zugeordnet, welche als dialektische Einheit von sexuellen und nicht-sexuellen Funktionen aufgefasst wird. Pervers ist sexuelle Aktivität dann, wenn innerhalb dieser Einheit eine nicht-sexuelle Funktion die Priorität über die Triebbefriedigung hat. Sexualität per se bezeichnet Homosexualität, Heterosexualität, Fetischismus, Sadomasochismus, Pädophilie usw. als verschiedene erwachsene Sexualorganisationen – als hierarchische Organisation von Partialtrieben – auf «gleichberechtigter», entpathologisierter Ebene. Nachdem begründet wird, weshalb auch Judith Le Soldat den Grund zur Homosexualität per se anscheinend nicht gefunden hat und alle bisherigen psychogenetischen Herleitungen der verschiedenen erwachsenen Sexualorganisationen dieses Ziel verfehlen, empfiehlt sich ein grundsätzlicher Verzicht auf solche Erklärungsversuche – so wie es für die Heterosexualität per se meistens gehandhabt wird. Dagegen kann auf den u. a. von Robert Stoller verwendeten Begriff imprinting oder Prägung zurückgegriffen werden, welchen die Zürcher Analytiker Harold Lincke und Werner Fessler von jeglichem Biologismusverdacht befreit haben. Zum Schluss wird hervorgehoben, wie sehr Morgenthaler und Le Soldat mit ihrer Suche nach dem Grund zur

Vor allem ihre unterschiedliche Wechselwirkung mit dem natürlichen Wasserstoff und seinem schweren Isotop Deuterium ermöglicht tiefe Einblicke in Struktur, Funktion und Dynamik von Proteinen, Nukleinsäuren und Biomembranen. Bei vielen Fragestellungen zur Strukturaufklärung gibt es kaum oder keine Alternative zum Neutron. Das Institut Laue-Langevin trägt Bahnbrechendes zum Erfolg der Neutronen-Methoden in der Biologie bei.

Full Text Available Soil management influences soil cover by crop residues and plant canopy, affecting water erosion. The objective of this research was to quantify water and soil losses by water erosion under different soil tillage systems applied on a typical aluminic Hapludox soil, in an experiment carried out from April 2003 to May 2004, in the Santa Catarina highland region, Lages, southern Brazil. Simulated rainfall was applied during five soybean cropstages, at the constant intensity of 64.0 mm h-1. Treatments were replicated twice and consisted of: i conventional tillage on bare soil - control treatment (CTBS, ii conventional tillage on cultivated soil (CTCS, iii no-tillage on non tilled soil with burned crop residue (NTRB, iv no-tillage in non tilled soil with crop residue desiccated (NTRD, and v no-tillage on four-years interrupted soil tillage with crop residue desiccated - "traditional no tillage" (NTRT. Regardless of soybean cropstages, water losses were the highest for the CTCS than for the untilled soils, while soil losses were considerably higher in the CTCS treatment only until cropstage 3, in cultivated soil treatments. The NTRT was most effective treatment in terms of both water and soil loss reduction. Water infiltration should also be considered, when considering the soil erosion process caused by rainfall and its associated runoff, due to the management systems usually adopted in cultivated fields.O manejo do solo influencia a cobertura superficial pelo resíduo cultural e, juntamente com a cobertura do solo pela copa das plantas, afeta a erosao hídrica.

Full Text Available O termo clínico erosão dental é usado para descrever os efeitos físicos de uma perda localizada, crônica e patológica de tecido mineral dentário que é removido quimicamente da superfície dentária por meio de ácido ou substâncias quelantes, sem envolvimento bacteriano. Estudos apontam diversos tipos de vinho como agentes causadores de erosão dentária. O objetivo deste trabalho foi descrever o efeito erosivo de um vinho tinto brasileiro sobre o esmalte bovino previamente imerso em saliva humana e água. Foram obtidos 20 blocos de esmalte bovino (3 mm × 3 mm × 3 mm. A metade da superfície de cada bloco foi coberta com esmalte de unhas. 10 blocos foram imersos em água e 10 em saliva humana por 12 horas. Após esse período, as peças foram imersas em vinho por 1 hora, submetidas ao ultra-som com acetona, lavados e secos. As peças foram analisadas em microscopia eletrônica de varredura. Em todos os blocos analisados foi possível observar erosão na superfície do esmalte. Em 2 blocos essa erosão foi leve, caracterizando-se como um alargamento das ranhuras fisiológicas do esmalte. No restante dos blocos ocorreu erosão severa, sendo possível observar o aspecto de favos de mel dos prismas de esmalte. O efeito erosivo no grupo de blocos imerso em saliva e em água foi similar. Concluiu-se que o vinho utilizado nesta experiência produziu erosão significativa na superfície do esmalte, in vitro. A imersão em saliva, precedente à exposição ao vinho, não pôde proteger o esmalte bovino contra a desmineralização, neste modelo experimental

Full Text Available This paper investigates the syntactic behaviour of adverbial clauses in contemporary German and Italian. It focuses on three main questions: (i How many degrees of syntactic integration of adverbial clauses are there to be distinguished by an adequate grammatical description of the two languages? (ii Which linear and hierarchical positions in the structure of the matrix sentence can be occupied by adverbial clauses? (iii Which is the empirical distribution of adverbial clauses introduced by the conjunctions als, während, wenn, obwohl and weil in German, as well as quando, mentre, se, sebbene and perché in Italian? Responding to question (i, a distinction is drawn between strongly integrated, weakly integrated and syntactically disintegrated adverbial clauses. There are further degrees on the gradient of syntactic integration, which are not examined in this paper. Responding to question (ii, eight classes of structural positions in the matrix sentence are identified that can be occupied by adverbial clauses. Five of them are positions of syntactic integration, three are positions of disintegration. Responding to question (iii, the distribution of the ten classes of adverbial clauses is described on the basis of a corpus of internet data. Strongly integrated, weakly integrated and disintegrated adverbial clauses show clearly different distributions within the structure of the matrix sentence. Also the semantic classes of adverbial clauses (temporal, adversative, conditional, concessive, causal are distributed differently.

Individual differences in detecting rapidly presented fearful faces.

Full Text Available Rapid detection of evolutionarily relevant threats (e.g., fearful faces is important for human survival. The ability to rapidly detect fearful faces exhibits high variability across individuals. The present study aimed to investigate the relationship between behavioral detection ability and brain activity, using both event-related potential (ERP and event-related oscillation (ERO measurements. Faces with fearful or neutral facial expressions were presented for 17 ms or 200 ms in a backward masking paradigm. Forty-two participants were required to discriminate facial expressions of the masked faces. The behavioral sensitivity index d' showed that the detection ability to rapidly presented and masked fearful faces varied across participants. The ANOVA analyses showed that the facial expression, hemisphere, and presentation duration affected the grand-mean ERP (N1, P1, and N170 and ERO (below 20 Hz and lasted from 100 ms to 250 ms post-stimulus, mainly in theta band brain activity. More importantly, the overall detection ability of 42 subjects was significantly correlated with the emotion effect (i.e., fearful vs. neutral on ERP (r = 0.403 and ERO (r = 0.552 measurements. A higher d' value was corresponding to a larger size of the emotional effect (i.e., fearful--neutral of N170 amplitude and a larger size of the emotional effect of the specific ERO spectral power at the right hemisphere. The present results suggested a close link between behavioral detection ability and the N170 amplitude as well as the ERO spectral power below 20 Hz in individuals. The emotional effect size between fearful and neutral faces in brain activity may reflect the level of conscious awareness of fearful faces.

Magnetism of Minor Bodies in the Solar System: From 433 Eros, passing Braille, Steins, and Lutetia towards Churyumov-Gerasimenko and 1999 JU3.

Minor bodies in the solar system, such as asteroids and comets, are important sources of information for our knowledge of the solar system formation. Besides other aspects, estimation of a magnetization state of such bodies might prove important in understanding the early aggregation phases of the protoplanetary disk, showing the level of importance of the magnetic forces in the processes involved. Meteorites' magnetization measurements suggest that primitive bodies consist of magnetized material. However, space observations from various flybys give to date diverse results for a global magnetization estimation. The flybys at Braille and Gaspra indicate possible higher magnetization (~ 10-3 Am2/kg), while flybys at Steins and Lutetia show no significant values in the global field change illustrating low global magnetization. Furthermore, the interpretation of remote (during flybys) measurements is very difficult. For correct estimates on the local magnetization one needs (in the best case) multi-point surface measurements. Single point observation has been done by NEAR-Shoemaker on 433 Eros asteroid, revealing no signature in magnetic field that could have origin in asteroid magnetization. Similar results, no magnetization observed, have been provided by evaluation of recent data from ROMAP (Philae lander) and RPC-MAG (Rosetta orbiter) instruments from comet 67P/Churyumov-Gerasimenko. The ROMAP instrument provided measurements from multiple points of the cometary surface as well as data along ballistic path between multiple touchdowns, which support the conclusion of no global magnetization. However, even in case of the in-situ on surface observations the magnetization estimate has a limiting spatial resolution that is dependent on the distance from the surface (~ 50 cm in case of ROMAP). To get information about possible smaller magnetized grains distribution and magnetization strength, the sensor shall be placed as close as possible to the surface. For such

However, his standard of perfection changed over the years: from a character in whom the best and highest qualities of an individual might come into being, to a model of the hero able to stand as a symbol and guide for his fellow men, in particular those people Yeats felt mainly responsible for, the Irish. There is something Carlylean in this (Yeats knew and appreciated Carlyle, even though he did not like his style, but his view of the hero includes other models, like the tragic hero and the hero of myth. This paper takes into consideration two heroes who frequently recur in his work, Oisin and Cuchulainn, pointing to similarities and difference both in their qualities and functions. However, above and beyond them, it is the poet himself that emerges as a key figure of a hero in Yeats’s poetry, as the only one who can fulfil the double task of developing his self and playing an essential social and moral role.

An X-ray and Gamma-Ray Spectrometer (XGRS) is on board the Near Earth Asteroid Rendezvous (NEAR) spacecraft to determine the elemental composition of the surface of the asteroid 433 Eros. The Eros asteroid is highly oblate and irregular in shape. As a result, analysis methodologies are in many ways a divergence from comparable techniques. Complex temporal, spatial and instrument performance relationships must be accounted for during the analysis process. Field of view and asteroid surface geometry measurements must be modeled and then combined with real measurements of solar, spectral and instrument calibration information to derive scientific results. NEAR is currently orbiting 433 Eros and is in the initial phases of its primary data integration and mapping phases. Initial results have been obtained and bulk chemistry assessments have been obtained through specialized background assessment and data reduction techniques.

Dem Allgemeinen steht begrifflich das Besondere gegenüber. In diesem Sinne sind allgemeine Überlegungen zum Verstehen von Mathematik zu ergänzen durch Untersuchungen hinsichtlich des Verstehens der einzelnen mathematischen Disziplinen, insbesondere der Geometrie. Hier haben viele Schülerinnen und Schüler Probleme. Diese rühren hauptsächlich daher, dass eine fertige geometrische Konstruktion in ihrer statischen Präsentation auf Papier nicht mehr die einzelnen Konstruktionsschritte erkennen lässt; zum Nachvollzug müssen sie daher ergänzend in einer Konstruktionsbeschreibung festgehalten werden.

Full Text Available A Microbacia do Ribeirão Samambaia é uma importante fonte hídrica que abastece a área urbana de Catalão (GO. Localizada em uma área de Cerrado, nos municípios de Catalão e Goiandira, Goiás, é uma área que passa por um intenso processo de ocupação principalmente o uso agropecuário. A hipótese defendida neste trabalho é que o uso das terras na área pesquisada gerou sérios impactos ambientais sobre os sistemas pedológicos, pois ocorre um avanço antrópico sobre as áreas suscetíveis à erosão laminar. O objetivo desta pesquisa foi estabelecer a relação entre a dinâmica de uso das terras e a suscetibilidade erosiva, classificando a evolução do potencial à erosão laminar na Microbacia do Ribeirão Samambaia. Para isso gerou-se os mapas dos usos dos solos e de suscetibilidade erosiva para os anos de 2001, 2006, 2011, 2013 e 2015, que foram analisados de forma integrada, gerando o mapa de potencial à erosão laminar através dos programas SPRING 5.3 e do ARCGIS 10.2. Os resultados mostraram que houve aumento das classes de pastagens, agricultura e área urbana, com preponderância das duas primeiras, contrapondo-se com diminuição das áreas de vegetação nativa.  O potencial à erosão laminar mostrou o predomínio inicial das áreas de baixo potencial à erosão, que foi ultrapassado pelas áreas de médio potencial, junto ao intenso aumento das áreas de alto potencial à erosão, vindo de encontro com a hipótese levantada neste estudo. Concluiu-se que o avanço antrópico, na área estudada, desempenha o risco da degradação ambiental dos solos, podendo interferir na qualidade dos recursos hídricos.

Full Text Available A Equação Universal de Perda de Solos (EUPS é um modelo de predição de perda de solo segundo um produto da erosividade da chuva, Fator R, da erodibilidade do solo, Fator K, do comprimento de rampa, Fator L, da declividade da vertente, Fator S, da cobertura e do manejo, Fator C, e das práticas conservacionistas, Fator P. Esta metodologia de predição de perda de solos, tem também tem sido utilizada como um instrumento de avaliação de risco à erosão e como medida de planejamento em bacias de uso agrícola. Assim, o presente trabalho tem por objetivo identificar as mudanças da erosão do solo na Bacia do Rio Urucuia, Minas Gerais, Brasil, através dos resultados da EUPS para 1987 e 2007. A Bacia do Rio Urucuia é tributária da Bacia do Rio São Francisco, com aproximadamente 25.000 km², contribui com 10% de vazão e 18% da carga de sedimentos. A metodologia usou o SIG para obtenção do Fator Topográfico (LS e o Sensoriamento Remoto para a determinação dos fatores de cobertura e  manejo (C e práticas conservacionistas (P. A classificação das imagens Landsat-TM foi feita pelo método ISODATA para dois anos, 1987 e 2007. A análise multitemporal determinou para a área estudada a ocorrência de mudanças significativas na erosão do solo, no final de vinte anos. O fator mais significativo para a degradação e erosão foi o aumento das áreas agrícolas. Os resultados mostram a distribuição espacial das distintas áreas propensas à erosão na bacia, onde práticas conservacionistas são fundamentais na prevenção da perda de solo por erosão. A análise é importante para o planejamento ambiental, e pode dar subsídio ao estabelecimento de cenários que visem o desenvolvimento sustentável da bacia.

Full Text Available Superficial erosion is one of the main soil degradation agents and erosion rates estimations for different edaphicclimate conditions for the conventional models, as USLE and RUSLE, are expensive and time-consuming. The use of cesium-137 antrophogenic radionuclide is a new methodology that has been much studied and its application in the erosion soil evaluation has grown in countries as USA, UK, Australia and others. A brief narration of this methodology is being presented, as the development of the equations utilized for the erosion rates quantification through the cesium-137 measurements. Two watersheds studied in Brazil have shown that the cesium-137 methodology was practicable and coherent with the survey in field for applications in erosion studies.A erosão superficial é um dos principais agentes de degradação dos solos e estimativas das taxas de erosão para diferentes condições edafoclimáticas pelos modelos tradicionais como USLE, RUSLE, são onerosos e demorados.

To conduct a qualitative evaluation of adjunct supports (brief motivational messaging regarding goals delivered by email/website, contact centre dietitian assistance) offered by EatRight Ontario (ERO) for users of a website-based nutrition/activity goal setting/tracking feature (eaTracker "My Goals"). One-on-one semi-structured interviews were conducted with My Goals users in Ontario (n = 18) and Alberta (n = 5) recruited via the eaTracker website and ERO contact centre dietitians (n = 5). Interview transcripts were analyzed using content analysis. Participants had mixed experiences and perspectives with ERO motivational messaging. Messages targeted towards specific goals (e.g., tips, recipes) were generally well-liked, and generic messages (e.g., eaTracker login reminders) were less useful. No interviewed users had contacted ERO dietitians regarding goals, and dietitians reported encountering few callers asking for assistance while using My Goals. Limited user knowledge was one explanation for this finding. Participants provided suggestions to enhance these supports. Electronic motivational messaging and contact centre dietitian assistance have the potential to support achievement of goals set with website-based features. When considering using electronic messaging, researchers and practitioners should consider message content and delivery tailoring. Marketing that focuses on how contact centre dietitians can assist website users with their goals is needed when services are used in naturalistic settings.

O TNF-alfa (TNF-alfa lambda uma das principais citocinas envolvidas neste processo. OBJETIVO: Avaliar o papel do TNF-alfa na reabsorsão óssea e a ação dele no colesteatoma. MATERIAL E MÉTODOS: Foi realizado um levantamento e uma revisão crítica da literatura. RESULTADOS: Todos os autores estudados concordam com a importância do TNF-alfa no processo de reabsorção óssea presente no colesteatoma e com o grau de destruição observado. Diferentes trabalhos demonstraram que o TNF-alfa é capaz de provocar erosão óssea, através de diferentes vias de ação. Ele pode estimular a diferenciação e a maturação dos osteoclastos ou, ainda, agir na matriz óssea expondo-a à ação dos osteoclastos. Existe a possibilidade de inibir a ação do TNF-alfa, diminuindo seus efeitos e prevenindo a perda óssea em doenças como a artrite reumatóide. Não existe, entretanto, trabalhos específicos em colesteatoma. Não existe consenso sobre a sua localização. Estas diferenças, provavelmente, ocorrem devido à distribuição dos receptores. CONCLUSÃO: O TNF-alfa, presente no colesteatoma promove a reabsorsão óssea, juntamente com outras citocinas (RANKL e IL-1, estando relacionado com a presença de complicações.Cholesteatoma may cause bone erosion, with high morbidity and mortality rates.

The investigation attempted an analysis of the causes and remedies of the gap between ecological and climate-relevant requirements on the one hand and public and political action on the other hand. It presents a theoretical concept for an ecologically oriented social restructuring process which will support rational energy use and the appropriate research and development measures more strongly than it does now. While the Federal government intends a 25 % reduction of carbon dioxide emissions by 2005, an 80 % reduction is required on a long-term basis (e.g. by 2050). In view of this, the contribution of the German government is interpreted as a necessary but still insufficient contribution to sustainability. [German] Diese Studie erarbeitet einen Beitrag zur Analyse der Ursachen und Loesungsmoeglichkeiten fuer den Widerspruch zwischen umwelt- und klimarelevanten Handlungsnotwendigkeiten einerseits und den gesellschaftlichen Handlungsdefiziten andererseits. Weitergehend erbringt sie einen theoretisch-konzeptionellen Ansatz zum oekologischen Umbau der Industriegesellschaft. Dadurch wird konkret dazu beigetragen, die Politik zur rationellen Energieanwendung einschliesslich der Forschungs- und Entwicklungspolitik besser als bisher zu unterstuetzen. Ausgegangen wird von dem energie- und klimapolitischen Ziel der Bundesregierung, bis zum Jahr 2005 die CO{sub 2}-Emissionen gegenueber dem Referenzjahr 1990 um 25% zu reduzieren. Langfristig, bis etwa zum Jahr 2050, ist nach der Empfehlung der Klima-Enquete-Kommission eine CO{sub 2}-Reduktion um 80% erforderlich. Dieser Beitrag der Bundesrepublik zum internationalen Klimaschutz kann als notwendige, wenn auch noch nicht hinreichende Voraussetzung fuer eine 'zukunftsfaehige Entwicklung' (sustainability) in der Bundesrepublik interpretiert werden.

1995-01-01

The plasma induced erosion and redeposition at the vessel walls in today's fusion devices have been investigated both with the computer simulation code ERO, and in experiments. Well prepared carbon probes with implanted and evaporated markers in the surface layers have been exposed in the scrape-off layer (SOL) of several tokamaks such as JET, TEXTOR and ASDEX-Upgrade. The main plasma parameters (electron density and temperature, impurity concentration in the SOL) are simultaneously determined. After exposure to single plasma discharges, erosion and redeposition of the marker material were measured by surface layer analysis with MeV ion beam techniques. The experimental results were compared with the results from the ERO code. The measured erosion/redeposition could be described with ERO, which takes into account the impurity concentration in the SOL, the dynamical change of the surface composition (causing a modification of the sputtering yield during the exposure) and ExB drift effects.

Moisture migration largely impacts cake crumb firmness during storage at ambient temperature. To study the importance of phenomena other than crumb to crust moisture migration and to exclude moisture and temperature gradients during baking, crustless cakes were baked using an electrical resistance oven (ERO). Cake crumb firming was evaluated by texture analysis. First, ERO cakes with properties similar to those baked conventionally were produced. Cake batter moisture content (MC) was adjusted to ensure complete starch gelatinisation in the baking process. In cakes baked conventionally, most of the increase in crumb firmness during storage was caused by moisture migration. Proton nuclear magnetic resonance ((1)H NMR) showed that the population containing protons of crystalline starch grew during cake storage. These and differential scanning calorimetry (DSC) data pointed to only limited amylopectin retrogradation. The limited increase in amylopectin retrogradation during cake storage cannot solely account for the significant firming of ERO cakes and, hence, other phenomena are involved in cake firming.

Purpose: How much can the radiation dose be reduced for skull radiography by using digital luminescence radiography (DLR) compared to a conventional screen film system with a grid cassette? Methods and Materials: A skull phantom (3M) was X-rayed in anterior-posterior orientation using both a conventional screen film system with grid cassette and DLR (ADC-70, Agfa). The tube current time product (mAs) was diminished gradually while keeping the voltage constant. The surface entrance dose was measured by a sensor of Dosimax (Wellhoefer). Five investigators evaluated the images by characteristic and critical features, spatial resolution and contrast. Results: The surface entrance dose at 73 kV/22 mAs was 0,432 mGy in conventional screen film system and 0,435 mGy in DLR. The images could be evaluated very well down to an average dose of 71% (0,308 mGy; SD 0,050); sufficient images were obtained down to an average dose of 31% (0,136 mGy; SD 0,065). The resolution of the line pairs were reduced down to a 2 levels depending on the investigator. Contrast was assessed as being very good to sufficient. The acceptance of the postprocessed images (MUSICA-software) was individually different and resultde in an improvement of the assessment of bone structures an contrast in higher dose ranges only. Conclusion: For the sufficient assessment of a possible fracture/of paranasal sinuses/of measurement the skull the dose can be reduced to at least 56% (31%; SD 14,9%)/40% (27%; SD 9,3%)/18% (14%; SD 4,4%). Digital radiography allows question-referred exposure parameters with clearly reduced dose, so e.g. for fracture exclusion 73 kV/12,5 mAs and to skull measurement 73 kV/4 mAs. (orig.)

From the present report 'Untersuchungen zur Radionuklidfreisetzung und zum Korrosionsverhalten von bestrahltem Kernbrennstoff aus Forschungsreaktoren unter Endlagerbedingungen' with the code number FKZ 9108 carried out in the time periode 01.06.1998 till 30.11.2001 the following results can be withdrawn: U/Al-RR-fuel elements corroded slowly in granite water (Grimsel-West) at 90 C under anaerobic conditions. For a complete dissolution of the fuel element a time period of 10{sup 3} years is assumed according to present conservative results. In salt brines, especially in magnesium chloride rich brines the corrosion rate is high. Addition of GGG40 (basic material of the fuel element container with iron as main element) had an acceleration effect. A complete dissolution of the fuel is achieved within a couple of months. Under aerobic and under anaerobic conditions the bulk of released radionuclides were fixed by the corrosion products formed (secondary phases). The actinides were mobilised by variation of the ionic strength of the leaching solution. This process can be explained by phase conversion reactions within the secondary phases. Secondary phases formed by corrosion of a non-irradiated U/Al-RR-fuel element, were analysed and hydrotalcites were identified as phase components. This result justifies the assumption, that hydrotalcites are components of the corrosion products from irradiated fuels. To clarify the questions which bindings exist between radionuclides and secondary phases, sorption experiments were performed. The sorption experiments were performed in salt brines and in granite water using repository relevant radionuclides and minerals which are considered to represent thermodynamic final components of the secondary phases. Pu sorbed as cationic species quantitatively and the binding is covalent. In granite water the same behaviour was found for Am. (orig.)

Within the framework of periodic safety inspection of the Gundremmingen power station (RWE-Bayernwerk - KRB II), the load collectives used for the design of safety-relevant systems and components were checked for their consistency with latest updates of the design basis. It was found that there was no analytical information or study available describing a particular process and its effects, namely switch-off of the high-pressure feedwater pump of the emergency core cooling system. The paper reports the work performed for closing the gap, including preparatory analyses, accompanying measures such as vibration measurements during plant shut-down, as well as the preparation and performance of the in-situ test. The experimental results and the comparative evaluation of calculated and experimental data are presented. (orig./CB) [Deutsch] Im Rahmen der periodischen Sicherheitsueberpruefung des Kernkraftwerkes Gundremmingen (Kernkraftwerke RWE-Bayernwerk - KRB II) wurden u.a. die Lastkollektive, die zur Auslegung sicherheitstechnisch relevanter Systeme und Komponenten herangezogen wurden, auf Aktualitaet ueberprueft. Dabei zeigte sich, dass bislang fuer eine Betriebsweise - naemlich das Abschalten der Hochdruckeinspeisepumpe des nuklearen Not- und Nachkuehlsystems (TH-HD-Pumpe) - keine analytischen Untersuchungen vorliegen. Vorbetrachtungen fuer analytische Untersuchungen, begleitende Massnahmen wie Schwingungsmessungen waehrend des Anlagenstillstandes, sowie der Versuchsaufbau und die Versuchsdurchfuehrung des Anlagenversuches werden hier dargestellt.

The project comprised the following stages: 1. Development of a technology for purification of soils contaminated with explosives. The process comprised soil washing, hot steam treatment, and thermal treatment of residues; 2. Projecting, construction and two years of operation of a soil purification plant with a rated throughput of 20 t/h and a total throughput of 130,000 t; 3. Remediation of two representative sites on DAG terrain (TNT production chain and filling stations); 4. Verification of the findings in an accompanying scientific programme. The site under investigation was formerly occupied by the Dynamit AG (DAG) Stadtallendorf, where TNT, contaminated waste water and acids were produced, and contamination levels were high in several areas. Today, the area is a residential area. In addition to the investigations described here, the waste water discharge system of the DAG was modernized.

Zum Bildungspotenzial biblischer Texte

Full Text Available Biblical education as a holistic process goes far beyond biblical learning. It must be understood as a lifelong process, in which both biblical texts and their understanders operate appropriating their counterpart in a dialogical way. – Neither does the recipient’s horizon of understanding appear as an empty room, which had to be filled with the text only, nor is the latter a dead material one could only examine cognitively. The recipient discovers the meaning of the biblical text recomposing it by existential appropriation. So the text is brought to live in each individual reality. Both scientific insights and subjective structures as well as the understanders’ community must be included to avoid potential one-sidednesses. Unfortunately, a special negative association obscures the approach of the bible very often: Still biblical work as part of religious education appears in a cognitively oriented habit, which is neither regarding the vitality and sovereignty of the biblical texts nor the students’ desire for meaning. Moreover, the bible is getting misused for teaching moral terms or pontifications. Such downfalls can be disrupted by biblical didactics which are empowerment didactics. Regarding the sovereignty of biblical texts, these didactics assist the understander with his/her individuation by opening the texts with focus on the understander’s otherness. Thus each the text and the recipient become subjects in a dialogue. The approach of the Biblical-Enabling-Didactics leads the Bible to become always new a book of life. Understanding them from within their hermeneutics, empowerment didactics could be raised to the principle of biblical didactics in general and grow into an essential element of holistic education.

Camenzind, Max

Kompakte Objekte besitzen zum einen eine sehr hohe Dichte, und zum anderen sind sie durch die Tatsache charakterisiert, dass keine nuklearen Reaktionen mehr in ihrem Inneren stattfinden können. Aus diesem Grund können sie im Unterschied zu gewöhnlichen Sternen der Gravitation nicht mehr mit dem Druck des thermischen Gases widerstehen. In den Weißen Zwergen bzw. Neutronensternen wird der Gravitation der Quantendruck eines Elektronengases bzw. einer Neutronenflüssigkeit entgegengesetzt. Ein solches Gas besteht aus Elektronen bzw. Neutronen, die auf ihr niedrigstes Energieniveau zusammengepresst wurden. Durch die daraus resultierende hohe Bewegungsenergie der Fermionen wird der sogenannte Quantendruck erzeugt.

Dynamic control of low-Z material deposition and tungsten erosion by strike point sweeping on DIII-D

Directory of Open Access Journals (Sweden)

J. Guterl

2017-08-01

Full Text Available Carbon deposition on tungsten between ELMs was investigated in DIII-D in semi-attached/detached H-mode plasma conditions using fixed outer strike point (OSP positions. Carbon deposition during plasma exposure of tungsten was monitored in-situ by measuring the reflectivity of the tungsten sample surface. No significant carbon deposition, i.e., without strong variations of the reflectivity, was observed during these experiments including discharges at high densities. In contrast, ERO modeling predicts a significant carbon deposition on the tungsten surface for those high density plasma conditions. The surface reflectivity decreases with methane injection, consistent with increased carbon coverage, as expected. The sweeping of OSP leads to a pronounced increase of the surface reflectivity, suggesting that the strike point sweeping may provide an effective means to remove carbon coating from tungsten surface. The ERO modeling however predicts again a regime of carbon deposition for these experiments. The discrepancies between carbon deposition regime predicted by the ERO model and the experimental observations suggest that carbon erosion during ELMs may significantly affect carbon deposition on tungsten.

Aim: This pilot study describes use of whole body PET (WB PET) for staging of melanoma. WB PET in conjunction with lymphoscintigraphy (LS) for evaluating status of the sentinel lymph node (SLN) in primary melanoma was investigated with comparison to histopathological results. WB PET was also used both for primary and metastatic melanoma for screening for distant metastases, restaging and follow-up. Methods: Group I: 17 patients with primary cutaneous melanoma underwent LS, WB PET and SLN dissection. WB PET findings were compared with biopsy results at the SLN site and were used for screening for distant metastases. Group II: 17 patients with a history of melanoma underwent WB PET for follow-up and/or restaging. Results were confirmed or refuted by other radiological modalities or by biopsy of clinical follow-up. Results: Group I: Out of 20 SLNs identified by LS in the 17 patients, 18 were negative on WB PET and 2 were positive. 19/20 WB PET findings were confirmed either by histopathology or by clinical follow-up (20 mo). Accuracy was 94% for the assessment of the status of the SLN. Group II: WB PET findings altered staging and treatment in 12/17 patients and confirmed the validity of treatment in 3/17 patients. Overall, in 15/17 patients (88%), WB PET had an impact on treatment strategy. (orig.) [German] Ziel: Diese Pilot-Studie beschreibt die Anwendung der Ganzkoerper-PET (WB PET) zum Staging beim Melanom.

Full Text Available The evolutionary function of love is to create a strong bond between the partners with reproduction in view. In order to achieve this goal, humans use various sexual/reproductive strategies, which have evolved due to specific reproductive benefits. The use of particular strategies depends on many factors but one of the most important is early childhood experiences, on which life history theory (LHT focuses. John Lee (1973 identified 6 basic love styles: eros, ludus, storge, pragma, agape, and mania. Our goal was to check whether love styles may be treated as sexual/reproductive strategies in the context of LHT - slow or fast strategy. In our study (N = 177 we found that people who prefer the slow reproductive strategy are inclined to show passionate, pragmatic and friendly love, and those who prefer the fast strategy, treated love as a game. A low level of environmental stress in childhood results in preferring eros, storge and agape love styles, belonging to the slow strategy, and a high one results in preferring ludus, which belongs to the fast strategy. People representing eros, storge or pragma styles have restricted sociosexual orientation so they prefer long-term relationships, whereas those with the ludus style are people with unrestricted orientation, preferring short-term relationships. Besides, storge, agape and pragma seem to determine preferring qualities connected with parental effort in one’s partner, mania - with mating effort, and eros - with both kinds of effort. No correlation was found between the love style and the number of children.

The Eckert number phenomenon - experimental investigations of heat transfer on moving walls, e.g. rotating cylinders; Das Eckert-Zahl-Phaenomen - Experimentelle Untersuchungen zum Waermeuebergang an einer bewegten Wand am Modellfall eines rotierenden Zylinders

The Eckert number phenomenon - theoretically investigated by Geropp in 1969 - describes a turnover in heat transfer at a moving wall at an Eckert number EC=1. This report is the first to confirm the Eckert number phenomenon experimentally. Heat transfer on a heated, vertically rotating cylinder in a crossflow was investigated at extreme rotational speeds, i.e. in the range where the predicted phenomenon will occur. A heating concept had to be developed which allowed an input of heating power independent of rotational speed and which therefore had to be contact-free. The complex thermofluiddynamic processes in the boundary layer around the rotating cylinder were investigated and measured using predominantly optical measuring techniques. The results show that the temperature difference between the wall and the surrounding fluid had a significant effect on the predicted turnover of heat transfer at the wall. Moreover, maximum heat transfer occurs at an Eckert number Ec=0.3, which is of great importance for the cooling of hot surfaces in an airstream. [German] Das Eckert-Zahl-Phaenomen - von Geropp 1969 theoretisch untersucht - beschreibt den Umschlag des Waermeueberganges an einer bewegten Wand bei einer Eckert-ZahlEc{approx}1. In der vorliegenden Arbeit wird das Eckert-Zahl-Phaenomen zum ersten Mal experimentell bestaetigt. Dazu wurde der Waermeuebergang am Modellfall eines queransgestroemten, beheizten, vertikalrotierenden Zylinders untersucht. Aufgrund der fuer die Experimente notwendigen extremen Drehzahlen musste fuer die Zylinderheizung ein Konzept entwickelt werden, das eine beruehrungsfreie und damit drehzahlunabhaengige Leistungseinspeisung erlaubte. Mit vorwiegend optischen Messmethoden wurden die komplexen thermofluiddynamischen Vorgaenge in der Grenzschicht um den rotierenden Zylinder untersucht und vermessen. Die Ergebnisse zeigen u.a., dass die Temperaturdifferenz zwischen Wand und Umgebung von entscheidender Bedeutung fuer die Richtungsumkehr des

Reformulating opioid analgesics to deter abuse is one approach toward improving their benefit-risk balance. To assess sentiment and attempts to defeat these products among difficult-to-reach populations of prescription drug abusers, evaluation of posts on Internet forums regarding reformulated products may be useful. A reformulated version of OxyContin (extended-release oxycodone) with physicochemical properties to deter abuse presented an opportunity to evaluate posts about the reformulation in online discussions. The objective of this study was to use messages on Internet forums to evaluate reactions to the introduction of reformulated OxyContin and to identify methods aimed to defeat the abuse-deterrent properties of the product. Posts collected from 7 forums between January 1, 2008 and September 30, 2013 were evaluated before and after the introduction of reformulated OxyContin on August 9, 2010. A quantitative evaluation of discussion levels across the study period and a qualitative coding of post content for OxyContin and 2 comparators for the 26 month period before and after OxyContin reformulation were conducted. Product endorsement was estimated for each product before and after reformulation as the ratio of endorsing-to-discouraging posts (ERo). Post-to-preintroduction period changes in ERos (ie, ratio of ERos) for each product were also calculated. Additionally, post content related to recipes for defeating reformulated OxyContin were evaluated from August 9, 2010 through September 2013. Over the study period, 45,936 posts related to OxyContin, 18,685 to Vicodin (hydrocodone), and 23,863 to Dilaudid (hydromorphone) were identified. The proportion of OxyContin-related posts fluctuated between 6.35 and 8.25 posts per 1000 posts before the reformulation, increased to 10.76 in Q3 2010 when reformulated OxyContin was introduced, and decreased from 9.14 in Q4 2010 to 3.46 in Q3 2013 in the period following the reformulation.

Walp. e cobertura morta (MN+F+CM e mandioca em nível consorciada com feijão-caupi (MN+F. A classificação do regime de escoamento superficial como laminar lento permitiu indicar a ocorrência de erosão entressulcos nos tratamentos MMA e MN+F. O tratamento MMA mostrou-se uma prática susceptível à erosão hídrica, proporcionando perda total de solo de 3.912 kg ha-1 e 21,5% de água, sendo 8,1 e 9,3 vezes maior em relação ao tratamento MN+F, enquanto nos tratamentos com cobertura morta não ocorreu erosão hídrica. A aplicação de cobertura morta e consórcio de culturas reduziram significativamente as perdas de solo e água, podendo ser utilizada pelos agricultores como técnica de conservação do solo e água.

Asteroids: up close and personal

Energy Technology Data Exchange (ETDEWEB)

Chapman, Clark R. [Southwest Research Institute (United States)

2001-06-01

Think of our solar system. The Sun, the Moon and the nine planets come to mind first, followed by the moons of other planets and other small bodies like asteroids. In 1991, almost 30 years after planetary exploration began, an asteroid was visited by a passing spacecraft for the first time. Nearly another decade elapsed before the first dedicated asteroid mission went into orbit around Eros, a city-sized object some 34 km long. And earlier this year, the NEAR, Shoemaker spacecraft daringly descended to the surface of Eros and landed safely. Asteroids have been pushed to the tail-end of the itinerary of solar-system exploration because of their diminutive sizes. Indeed, the wealth of low-gravity phenomena associated with asteroids has captured the imagination of both researchers and the public alike. In the June issue of Physics World Clark R Chapman of the Southwest Research Institute, US, explains how the landing of a spacecraft on the asteroid Eros earlier this year has given space scientists the best view yet of small planetary bodies and has opened a new window on the solar system.

Different redox sensitivity of endoplasmic reticulum associated degradation clients suggests a novel role for disulphide bonds in secretory proteins.

To maintain proteostasis in the endoplasmic reticulum (ER), terminally misfolded secretory proteins must be recognized, partially unfolded, and dislocated to the cytosol for proteasomal destruction, in a complex process called ER-associated degradation (ERAD). Dislocation implies reduction of inter-chain disulphide bonds. When in its reduced form, protein disulphide isomerase (PDI) can act not only as a reductase but also as an unfoldase, preparing substrates for dislocation. PDI oxidation by Ero1 favours substrate release and transport across the ER membrane. Here we addressed the redox dependency of ERAD and found that DTT stimulates the dislocation of proteins with DTT-resistant disulphide bonds (i.e., orphan Ig-μ chains) but stabilizes a ribophorin mutant (Ri332) devoid of them. DTT promotes the association of Ri332, but not of Ig-µ, with PDI. This discrepancy may suggest that disulphide bonds in cargo proteins can be utilized to oxidize PDI, hence facilitating substrate detachment and degradation also in the absence of Ero1. Accordingly, Ero1 silencing retards Ri332 degradation, but has little if any effect on Ig-µ. Thus, some disulphides can increase the stability and simultaneously favour quality control of secretory proteins.

Patienten und Methoden: Wir vergleichen 131-Iod- mit 111-In-Pentetreotide-Szintigraphien bei 24 Patienten mit metastasiertem, nicht-medullaeren Schilddruesenkarzinom. Die Befunde wurden mit anderen bildgebenden Verfahren korreliert. Zusaetzlich erfolgten Rezeptor-Autoradiographien bei einem Patienten, eine Octreotide-Behandlung bei einem anderen und die Verabreichung von 90-Y- sowie 111-In-DOTATOC bei zwei weiteren Patienten. Ergebnisse: Bei 8/15 Patienten mit papillaerem oder follikulaerem Schilddruesenkarzinom erwies sich 111-In-Pentetreotide dem 131-I- als unterlegen, bei 1/15 als gleichwertig und bei 6/15 als ueberlegen. Bei 8/9 Patienten mit onkozytaerem Schilddruesenkarzinom zeigten die Metastasen eine 111-In-Pentetreotide-Akkumulation unterschiedlicher Intensitaet, waehrend die 131-I-Szintigraphien hier bis auf eine Ausnahme negativ waren. Im Vergleich mit 201-Tl oder 99m-Tc-Sestamibi erwies sich 111-In-Pentetreotide als gleichwertig oder ueberlegen, aber im Vergleich zum 18-F-FDG-PET zumeist als unterlegen. Die Befunde der 111-In-Pentetreotide-Szintigraphie korrelierten gut mit der Rezeptor-Autoradiographie und der DOTATOC-Akkumulation, nicht dagegen mit dem Behandlungseffekt von `kaltem` Octreotide auf die Schilddruesenkarzinom-Metastasen. Schlussfolgerungen: Diverse Metastasen papillaerer und follikulaerer Schilddruesenkarzinome und die Mehrzahl der onkozytaeren Schilddruesenkarzinom-Metastasen koennen Somatostatin-Rezeptoren exprimieren. Insbesondere beim onkozytaeren Schilddruesenkarzinom beziehungsweise bei nicht verfuegbarem PET erweist sich die 111-In-Pentetreotide-Szintigraphie als vielversprechende Methode zur Metastasenlokalisation; sie konnte ferner von Nutzen sein bei der Selektion moeglicher Kandidaten fuer eine Therapie mit {beta}-Strahler-markierten Somatostatinanaloga, wenn diese fuer die

Overtraining syndrome (OTS) is caused by an imbalance between training, nutrition and resting, and leads to decreased performance and fatigue; however, the precise underlying triggers of OTS remain unclear. This study investigated the body composition, metabolism, eating, sleeping patterns and mood states among participants with OTS. Selected participants were divided into OTS-affected athletes (OTS, n = 14), healthy athletes (ATL, n = 25), and healthy non-physically active controls (NCS, n = 12). Compared to ATL, OTS showed decreased sleep quality (p = 0.004); increased duration of work or study (p sleep, and increased cognitive activity are likely OTS triggers. OTS appears to induce dehydration, increase body fat, decrease libido, and worsen mood.

Auberdem wurden die Veranderungen, die die Technologie gebracht hat, zu den Wirkungen in der schriftlichen und elektronischen Presse berührt. Der Import von teurer und verschwenderischer Technologie, die Tatsache, dass die Erhöhung der Eingabepreise den Vertriebspreisen von Zeitungen nicht entgegenkommen konnte, und der sich mit den 80'igern beschleunigende Werbe-Promotionswettbewerb erhöhten die Gestehungskosten im Pressesektor und brachten das Monopol mit sich. Die Neigung zum Monopol wirkte negativ auf die Nachrichtenproduktion, -Verteilung und die Gedankenfreiheit; die Arbeitsbedingungen und die Beschaffenheitsrechte der Pressearbeiter wurden eingeschrankt. Werbungen und unser Magazintage sind der Schwerpunkt der türkischen Presse. Exklusive - reiche Massen, Prominente, die man als 'Gesellschaftssahne' bezeichnet, Sanger und Sangerinnen die in Fernsehprogrammen berühmt wurden, und das private Leben von Entertainern haben einen groBen Platz in der Presse. Nachrichten, die die Gesellschaft oder die Zukunft des Landes interessieren, können bewusst auBer Acht gelassen werden und die Tagung besteht meistens aus Gerüchten mit vielen Bildern und groBen Buchstaben, die überhaupt keinen Nachrichtenwert haben. Letztendlich sollte man Zeitungen zum lesen und nicht zum anschauen drucken. Eine Zeitung sollte nicht mit dem Fernsehen oder dem Internet konkurrieren sondern in ihrer eigenen Rennstrecke bleiben.

The Herdorf sewage system is presented as an example of heat recovery from compressed air of the activation stage. Consumption of externally supplied fuel (heating oil) was minimised, and full-scale power generation from sewage gas provided additional income. The key element of the heat recovery system is the air cooler with a matched double-shell heat exchanger. Temperatures and water volumes on the heating water side can be varied in order to ensure optimum heat supply to the air cooler at any time. The heat is used in the internal heating system to heat up the raw sludge in the fermentation process. [German] Die Waermerueckgewinnung aus der Druckluft von Belebungsanlagen kann einen wesentlichen Beitrag zum Waermehaushalt von Klaeranlagen liefern, wie hier am Beispiel der Klaeranlage Herdorf erlaeutert wurde. Hierdurch konnte zum einen der Einsatz von Fremdbrennstoffen (Heizoel) auf ein Minimum reduziert und zum anderen konnten zusaetzliche Ertraege aus der vollstaendigen Verstromung des Faulgases erzielt werden. Kernstueck der Waermerueckgewinnungsanlage bildet der Luftkuehler und der darauf abgestimmte Doppelmantelrohr-Waermeuebertrager. Von wesentlicher Bedeutung ist hierbei, dass auf der Heizkreiswasserseite mit variablen Heizwassermengen und korrespondierenden Temperaturen gefahren werden kann, um zu jedem Zeitpunkt die optimale Waerme durch den Luftkuehler bedarfsorientiert abgreifen zu koennen. Die Waerme dient zur Einspeisung in das Betriebs-Heizungssystem und damit zur Rohschlamm-Aufheizung im Faulungsprozess. (orig.)

Die vorliegende überarbeitete Leitlinie zum Lipödem wurde unter der Federführung der Deutschen Gesellschaft für Phlebologie (DGP) erstellt und finanziert. Die Inhalte beruhen auf einer systematischen Literaturrecherche und dem Konsens von acht medizinischen Fachgesellschaften und Berufsverbänden. Die Leitlinie beinhaltet Empfehlungen zu Diagnostik und Therapie des Lipödems. Die Diagnose ist dabei auf der Basis von Anamnese und klinischem Befund zu stellen. Charakteristisch ist eine umschriebene, symmetrisch lokalisierte Vermehrung des Unterhautfettgewebes an den Extremitäten mit deutlicher Disproportion zum Stamm. Zusätzlich finden sich Ödeme, Hämatomneigung und eine gesteigerte Schmerzhaftigkeit der betroffenen Körperabschnitte. Weitere apparative Untersuchungen sind bisher besonderen Fragestellungen vorbehalten. Die Erkrankung ist chronisch progredient mit individuell unterschiedlichem und nicht vorhersehbarem Verlauf. Die Therapie besteht aus vier Säulen, die individuell kombiniert und an das aktuelle Beschwerdebild angepasst werden sollten: komplexe physikalische Entstauungstherapie (manuelle Lymphdrainage, Kompressionstherapie, Bewegungstherapie, Hautpflege), Liposuktion und plastisch-chirurgische Interventionen, Ernährung und körperliche Aktivität sowie ggf. additive Psychotherapie. Operative Maßnahmen sind insbesondere dann angezeigt, wenn trotz konsequent durchgeführter konservativer Therapie noch Beschwerden bestehen bzw. eine Progredienz des Befundes und/oder der Beschwerden auftritt. Eine begleitend zum Lipödem bestehende morbide Adipositas sollte vor einer Liposuktion therapeutisch angegangen werden. © 2017 The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.

Within the framework of an R and D project sponsored by the Deutsche Bundesstiftung Umwelt, cleaning of process and excess water from organic waste fermentation plants was studied at the Institute for Siedlungswasserwirtschaft of Aachen Technical University RWTH. The focus in studying these waste waters was on the adaptation and optimization of the ZenoGem {sup trademark} process - a biological cleaning technique with an integrated microfiltration membrane. The use of this technology had the following objectives: to safeguard compliance with the limiting values for direct or indirect discharge of excess water and to reduce the heavy metal freight of circulating process water reentering the fermentation process for mashing raw organic waste. Thus the pollutant content of the fermentation residue was to be cut down. (orig.) [German] Im Rahmen eines von der Deutschen Bundesstiftung Umwelt gefoerderten Forschungs- und Entwicklungsvorhabens wurde am Institut fuer Siedlungswasserwirtschaft der RWTH Aachen die Prozess- und Ueberschusswasserreinigung von Bioabfallvergaerungsanlagen untersucht. Dabei stellte die Adaption und Optimierung des ZenoGem {sup trademark} -Verfahrens - ein biologisches Reinigungsverfahren mit integrierter Mikrofiltrationsmembran - fuer diese Abwaesser den Untersuchungsschwerpunkt dar. Ziel war es, mit dieser Technologie zum einen die Grenzwerte fuer eine direkte oder indirekte Einleitung des Ueberschusswassers zu gewaehrleisten und zum anderen die zirkulierenden Prozesswaesser, die in den Vergaerungsprozess zum Anmaischen der Roh-Bioabfaelle zurueckgefuehrt werden, an Schwermetallen zu entfrachten. Hierdurch sollte eine Schadstoffreduktion im Gaerreststoff erzielt werden. (orig.)

Im Anschluss an die heuristische Studie Globalität und Interkulturalität als integrale Bestandteile beruflicher Bildung für eine nachhaltige Entwicklung (GInE, www.ibw.uni-hamburg.de/GInE wurde ein didaktisches Strukturgitter entworfen, das exemplarische Problemlagen und Dilemmata benennt, so wie Reflexionskategorien für die Hochschuldidaktik in der beruflichen Lehrerbildung zur Diskussion stellt.As a regulative concept, the idea of sustainability implies a number of theorems in the field of humanities. It is regarded as supercomplex and, thus, could not yet be systematically transformed in university didactics. Large scale conceptual terms such as justice, responsibility, participation, retinity, globality, and interculturality are at the core of the discussion – terms which run through basic texts, policy papers, and programmes as focal points of the idea of sustainability. With respect to the heuristic study Globality and Interculturality as Integral Elements of a Professional Education for a Sustainable Development (GInE, www.ibw.uni-hamburg.de/GInE, a didactic framework was designed which not only denotes exemplary problems and dilemmata but also puts up categories of reflection for a university didactics aiming at a professional teacher training.

Full Text Available Exercícios físicos associados a uma dieta balanceada são importantes fatores para a promoção da saúde. Contudo, a realização de exercícios físicos intensos e prolongados ou de caráter exaustivo pode promover inflamação crônica, overtraining e maior susceptibilidade a infecções. Sendo causa ou consequência, um dos fatores que contribuem para estes efeitos é o aumento exacerbado da síntese de compostos pró-oxidantes, conhecidos como espécies reativas do oxigênio (ERO e nitrogênio (ERN. O aumento de ERO e ERN pode reduzir a capacidade antioxidante corporal, situação conhecida como estresse oxidativo. O estresse oxidativo tem sido relacionado como promotor de lesões a diversos constituintes celulares, principalmente sobre as membranas, efeito denominado como peroxidação lipídica. Para neutralizar os efeitos das ERO e ERN, o organismo dispõe do sistema de defesa antioxidante, localizado em diferentes compartimentos celulares e com funções diversas. Estudos têm, cada vez mais, demonstrado que o sistema antioxidante pode ser influenciado por intervenções nutricionais específicas, dentre as quais se incluem vitaminas, minerais, flavonóides e aminoácidos. Considerando o fato de muitas pessoas iniciarem a prática de exercícios físicos a cada dia, e que muitas destas ultrapassam seus limites, esta revisão visa abordar os principais sítios de síntese de ERO e ERN durante exercícios físicos, bem como possíveis estratégias nutricionais e seus mecanismos de ação sobre o sistema de defesa antioxidante.

Representations of Eros: From Modernismo to Posmodernismo

Directory of Open Access Journals (Sweden)

Alicia Rita Rueda-Acedo

2014-12-01

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

Full Text Available On the basis of Bernhard Welte’s Dialectic of Love, the article develops a hermeneutic-phenomenological analysis of the ontological, chronological, and cosmic-religious meaning of eros. The article has three purposes. First, it attempts to show how the acknowledged cognitive capacity of love, which enables to see the particularity of the loved thou in a way that is inaccessible to objective knowledge, leads to an ontological con-creative event. Second, an elucidation of synchrony as the temporality essential to eros as an event is advanced. Finally, the article shows the degree in which erotic love is the sign-event of a cosmic-religious type of harmony that links lovers with all things.

Full Text Available (nemački Heideggersche erste Bewegungen in Richtung auf die Funda­mentalontologie lassen sich in seinen Vorlesungen der frühen 20er Jahren beobachten. Heidegger versucht darin, sich von dem Logizismus der Husserlschen Bewusstseinsphilosophie zu emanzipieren, indem er ein Konzept der Urwissenschaft entwirft. Die Urwis­senschaft soll bei der vortheoretischen Erfahrung, d. h. bei den vorreflexiven Erlebnissen ansetzen. Sie hat der entlebenden Tendenz der theoretischen Einstellung zum Erlebnis­strom entgegenzuwirken und somit die Voraussetzungen dafür zu schaffen, eine Viel­falt der lebendigen Erfahrungsweisen zum ausdrücklichen Verstehen zu bringen. Somit knüpft die Urwissenschaft an das Programm der Phänomenologie von Edmund Husserl, modifiziert es aber entscheidend, indem es aus der Sphäre des Bewusstseins in jene des lebendigen Erlebnisstroms verlegt.

Full Text Available A erosão acelerada do solo, um processo basicamente induzido pela ação antrópica, muito contribui para a degradação da qualidade das terras aráveis em todo o mundo, além de constituir a principal fonte não pontual de poluição dos recursos hídricos superficiais. Considerando a demanda efetiva pelo desenvolvimento de indicadores para avaliação do impacto da erosão na qualidade do solo em sistemas de produção agrícola, este trabalho teve por objetivo desenvolver um índice, com valor prognóstico, para ser aplicado como uma ferramenta de planejamento na interpretação da tolerância de perda de solo em áreas agrícolas. Foi desenvolvido o método designado "Índice de Tempo de Vida do Solo", para se proceder ao diagnóstico da erosão em uma área predominantemente utilizada com a cultura da cana-de-açúcar no município de Piracicaba (SP. Na realização do trabalho, foram empregados geotécnicas e métodos de análise geoestatística, sendo o processamento e a análise dos dados efetivados em ambiente de sistema de informação geográfica do tipo matricial. As taxas anuais médias de perda de solo foram estimadas em trabalho anterior, empregando a equação universal de perda de solo (EUPS, com ajuste dos fatores do modelo às condições locais da área de estudo. Nos cálculos do índice de tempo de vida do solo, foi presumida uma taxa de renovação de 0,2 mm ano-1 e foram analisadas duas profundidades, de 50 e de 100 cm, consideradas mínimas para o uso agrícola. A avaliação da espessura do solum revelou que, na área de estudo, predominam solos pouco profundos, com médias ponderadas pelas áreas de ocorrência de 78 cm, solos ocupados com cana-de-açúcar, e de 72 cm, solos ocupados com outros usos. A aplicação do índice de tempo de vida revelou que, adotando a profundidade crítica de 50 cm, o tempo de vida médio do solo nas áreas ocupadas com cana-de-açúcar é de 178 anos, e que, mantida a expectativa atual

Tamoxifen ist mit einem ca. zweifach erhöhten Risiko für thrombembolische Komplikationen (tiefe Beinvenenthrombose, Lungenembolie assoziiert. Vor dem Hintergrund einer aktuellen und im Februar 2012 im Journal of Plastic and Reconstructive Surgery erschienenen retrospektiven Studie mit Nachweis einer erhöhten Komplikationsrate freier Lappentransplantate zur Brustrekonstruktion unter Tamoxifen-Einnahme haben wir unser Patientenkollektiv nach mikrochirurgischer Brustrekonstruktion retrospektiv auf Minor- und Major-Komplikationen einschließlich thrombembolischer Ereignisse insbesondere vor dem Hintergrund einer perioperativen Tamoxifeneinnahme untersucht. Eingeschlossen wurden insgesamt 29 Patientinnen nach mikrochirurgischer autologer Brustrekonstruktion. Es wurden mikrovaskuläre Lappenkomplikationen und Lappenverluste von Patientinnen ohne und mit Einnahme von Tamoxifen und Aromatasehemmern zum Zeitpunkt der mikrochirurgischen Brustrekonstruktion verglichen. 25 Patientinnen (86,2% erhielten eine DIEP-Lappenplastik und 4 (13,8% eine TRAM-Lappenplastik. Fernerhin verglichen wir die Rate allgemeiner thrombembolischer Ereignisse unter Berücksichtigung sonstiger Nebendiagnosen und Risikofaktoren. Von insgesamt 29 Patientinnen standen zum Zeitpunkt der mikrovaskulären Brustrekonstruktion 3 unter einer Aromatasehemmer-Therapie und 5 unter einer Tamoxifen-Therapie. Insgesamt traten in 11 Fällen (37,9% postoperative Komplikationen auf, in 5 Fällen handelte es sich hierbei um Major-Komplikationen (mit einem Lappenverlust und in um Minorkomplikationen. Unter Tamoxifeneinnahme kam es in einem Fall zu einer Minorkomplikation, und in einem anderen Fall zu einem thrombembolisch bedingten Lappenverlust. Insgesamt kam es postoperativ zu einem thrombembolischen Ereignis in Form einer Lungenembolie ohne Assoziation zur Tamoxifen-Therapie.Die Anzahl thrombembolischer Ereignisse stellten sich mit und ohne

Full Text Available Práticas diferenciadas de manejo resultam em condições físicas de superfície e subsuperfície do solo distintas, as quais, por sua vez, resultam em níveis de erosão hídrica variados. Com isto em mente, realizou-se um estudo a campo com o objetivo de avaliar o efeito de formas de preparo e cultivo do solo e de manejo dos resíduos culturais em algumas de suas condições físicas de superfície e subsuperfície, em relação à erosão hídrica, durante 5,5 anos. Para tal, utilizou-se chuva simulada sobre um Argissolo Vermelho distrófico típico, bastante degradado pelo manejo anterior, com declividade de 0,08 m m-1. Os tratamentos consistiram dos cultivos de milho e aveia preta, em semeadura direta e em preparo convencional de solo (este com incorporação e com remoção dos resíduos culturais, e do sem cultivo, em preparo convencional de solo (testemunha. Tais tratamentos encontravam-se na condição de solo recém-mobilizado, ou consolidado, e desprovido de cobertura vegetal por ocasião dos testes de erosão com chuva simulada. Estes, em número de dez, foram realizados com o simulador de chuva de braços rotativos, na intensidade de 64 mm h-1 e duração de 90 min, logo após a colheita de uma cultura e o preparo do solo, ou não, para o estabelecimento da cultura seguinte. A incorporação sistemática dos resíduos culturais ao solo recuperou sua estrutura e diminuiu a perda de solo praticamente em 3/4, comparada a sua remoção, resultando também na menor perda de solo no estudo. Devido à recém-criada rugosidade superficial do solo, os tratamentos com preparo convencional apresentaram as maiores capacidades de retenção e infiltração de água, resultando em retardamento da enxurrada e, logo, baixa perda de água, comparados à semeadura direta, independentemente do cultivo e da incorporação ou remoção dos resíduos culturais. O preparo convencional sem cultivo, apesar de apresentar rugosidade superficial similar ao

Davies, M F

2001-09-01

In 2 experiments, the researcher investigated the social desirability of different love styles (Eros, Ludus, Storge, Pragma, Mania, and Agape). In Experiment 1, the Marlowe-Crowne measure of social desirability (D. P. Crowne & D. Marlowe, 1960) was correlated negatively with possessive, dependent (Mania) love styles in both men and women. In men, social desirability was correlated positively with romantic, passionate love (Eros) and game-playing love (Ludus), but negatively with all-giving, selfless love (Agape). In women, social desirability was correlated positively with Agape, but negatively with Ludus. In Experiment 2, the researcher replicated these findings using an impression management manipulation (good, bad, and honest responding). The gender differences in social desirability of different love styles are explained in terms of traditional and nontraditional gender role socialization.

Inflammatory muscle diseases are quite heterogeneous and frequently a specific diagnosis is not easy. Magnetic resonance imaging (MRI) is best suited to demonstrate pattern and size of inflamed muscles. Sensitivity of MRI in showing inflamed muscles is nearly 100%. Specificity, however, is much lower. In cases of suspected bacterial myositis, sonography may be used to exclude abscess formation prior to MRI for more precise information about inflamed muscles. (orig.) [German] Entzuendliche Muskelerkrankungen stellen eine heterogene Gruppe dar und sind mitunter nur schwer exakt zu diagnostizieren. Die Magnetresonanztomographie (MRT) stellt Ausdehnung und Befallsmuster am besten dar. Der Nachweis entzuendlicher Oedeme oder von Einschmelzungen gelingt mit der MRT in annaehernd 100 % der Faelle. Die Spezifitaet der Methode ist allerdings deutlich geringer. Bei Verdacht auf bakterielle Myositiden kommt erst die Sonographie zum Ausschluss von Einschmelzungen und dann die MRT zum Einsatz.
