Überblick über das deutsche Attribut am Beispiel des Romans von Thomas Mann „Der Zauberberg”
This article describes an attributive on the basis of a novel entitled “Der Zauberberg” of the famous German writer – Thomas Mann. This is a detailed analysis of the attributive and all examples come from the novel “Der Zauberberg”. At the outset of the article are quoted different definitions. Various classifications of attributive are presented. The article answers the questions: which part of speech can be used as an attributive. Finally I wishes to highlight the case of the subordinate clause, which also fulfil the role of an attributive and refer to the special form of attributive, namely to the apposition
Everywhere and all the time: accident, radical contingency, and Crash
What are the politics of the accident? This essay interrogates the accident trope’s dual meaning in critical theory and popular narrative as both historically endemic and conditional for a political theory of radical resistance and ethical relation. I explore this in Paul Haggis’ 2004 film Crash, a popular narrative that plots the accident to provide an opening for a politics of possibility and ethical engagement. However, this essay critiques efforts to situate accidents, and therefore contingency, as both historically endemic and politically resistant, arguing for the difficulty of reading a specific theory of political and ethical decision into something ontologically given. Crash stretches contingency to incorporate temporality itself, and in doing so nullifies consideration of institutional histories of race and class, which aesthetically foregrounds and troubles related assumptions made by a critical mode that too quickly reads a specific politics and ethics into contingency’s deviation from necessary law. The essay re-evaluates the accident’s political and ethical coordinates through reference to Ernesto Laclau and Chantal Mouffe’s theorisation of contingency as conditional for political meaning more generally. Accidents, it concludes, are politically and ethically mobile, if they, as Crash and theories of radical contingency contend, happen everywhere and all the time
The And of Modernism: On New Periodizations
The study of literary modernism is in the ascendant in the academy. From alternate modernisms, to neomodernisms, to metamodernism and global modernisms, modernism scholarship has evolved through a configuration of modernism into a cross-cultural and inter-generational aesthetic practice. This article critically examines the periodizing logic implicit in this new modernism scholarship, specifically as it pertains to the study of what is loosely called ‘neomodernism’, which we suggest presents a notable development in literary history for accounts of contemporary fiction and postmodern culture. We are principally interested in a recent trend we observe in modernism literary criticism concerning the futurization of the object (literary modernism), and of critical work thereupon. This work, which specifically addresses developments in contemporary Western Anglophone literature, seeks to extend the project of modernism (sometimes called its ‘promise’) into the present, understanding it as the principal agency in literary distinction and merit. We examine this criticism through a series of case studies, and discern three interconnecting strands in neomodernist criticism – three ways of futurizing modernism, and of self-futurizing modernism criticism
Avalia??o da germina??o de feij?o submetido a diferentes tratamentos com bioestimulante
Biostimulants are plant growth substances (auxin, gibberellin, cytokinins, etc.) that can act
alone or in combination, interfering in various physiological and / or morphological processes.
In the treatment of seeds, the use of biostimulant can influence root growth, percentage and
speed of germination, presenting variable responses depending on the crop. The objective of
this study was to evaluate the germination of bean seeds (Phaseolus vulgaris L.), BRS Esteio
cultivar, pre-soaked in different doses of a commercial biostimulant, composed of 50 mg L-1
of indolebutyric acid, 90 mg L -1 of kinetin and 50 mg L-1 of gibberellic acid. Eight (8)
treatments and four (4) replicates of 25 seeds per treatment were adopted, and the design was
completely randomized. The following treatments were used: T1: 0 mL (imbibition only in
sterile distilled water); T2: 1mL; T3: 2.5 mL; T4: 5 mL; T5: 7.5 mL; T6: 10 mL; T7: 25 mL;
T8: 50 ml of biostimulant per kg of seeds. The following variables were evaluated:
germination (%), germination speed index (IVG), mean shoot length (CMPA), mean root
length (CMR), fresh shoot mass (MFPA), dry shoot mass (MSPA), fresh root mass (MFR) and
root dry mass (MSR) of germinated seeds. The same treatment presented significantly higher
mean values for CMPA, CMR, MFR and MSR. The MFPA and MSPA variables were
negatively affected by biostimulant pre-soaking. It was concluded that the dose of 10 mL of
biostimulant per kg of seeds resulted in a higher percentage and speed of germination, shoot
and root lengthening, and increase of fresh and dry biomass of the roots, while the different
dosages of biostimulant in the treatment of bean seeds provided a decrease in the accumulation
of fresh and dry shoot biomass in the germinated seeds.Os bioestimulantes s?o subst?ncias de crescimento vegetal (auxina, giberelina, citocininas,
etc.) que podem atuar isoladamente ou em combina??o, interferindo em diversos processos
fisiol?gicos e/ou morfol?gicos. No tratamento de sementes, o uso de bioestimulante pode
influenciar o crescimento radicular, porcentagem e velocidade de germina??o, apresentando
respostas vari?veis dependendo da cultura. No presente estudo, objetivou-se avaliar a
germina??o de sementes de feij?o (Phaseolus vulgaris L.), cultivar BRS Esteio, pr?-
embebidas em diferentes doses de um bioestimulante comercial, composto por 50 mg L -1 de
?cido indolbut?rico, 90 mg L -1 de cinetina e 50 mg L -1 de ?cido giber?lico. Foram adotados
oito (8) tratamentos e quatro (4) repeti??es de 25 sementes por tratamento, sendo o
delineamento inteiramente casualizado. Os seguintes tratamentos foram empregados: T1: 0
mL (embebi??o somente em ?gua destilada est?ril); T2: 1 mL; T3: 2,5 mL; T4: 5 mL; T5: 7,5
mL; T6: 10 mL; T7: 25 mL; T8: 50 ml de bioestimulante por Kg de sementes. As seguintes
vari?veis foram avaliadas: germina??o (%), ?ndice de velocidade de germina??o (IVG),
comprimento m?dio da parte a?rea (CMPA), comprimento m?dio das ra?zes (CMR), massa
fresca da parte a?rea (MFPA), massa seca da parte a?rea (MSPA), massa fresca das ra?zes
(MFR) e massa seca das ra?zes (MSR) das sementes germinadas. A dose de 10 mL kg -1 de
sementes apresentou a maior porcentagem de germina??o (84%) e o maior IVG. O mesmo
tratamento apresentou significativamente as maiores m?dias para CMPA, CMR, MFR e MSR.
As vari?veis MFPA e MSPA foram afetadas negativamente pela pr?-embebi??o com
bioestimulante. Conclui-se que a dose de 10 mL de bioestimulante por Kg de sementes
resultou em maior porcentagem e velocidade de germina??o, alongamento da parte a?rea e
das ra?zes e, incremento da biomassa fresca e seca das ra?zes, enquanto as diferentes dosagens
de bioestimulante no tratamento de sementes de feij?o proporcionaram decr?scimo no
ac?mulo de biomassa fresca e seca da parte a?rea nas sementes germinadas
Morphology of the epithelial cells and expression of androgen receptor in rat prostate dorsal lobe in experimental hyperprolactinemia.
The effect of hyperprolactinemia on the prostate has not been well investigated. Since androgens play an important role in prostate development, growth and function, the goal of the present study was to estimate the influence of hyperprolactinemia on expression of the androgen receptor (AR) in rat epithelial cells of prostate dorsal lobe and on morphology of these cells. Studies were performed on sexually mature male Wistar rats. The experimental group rats received metoclopramide (MCP) intraperitoneally to provoke hyperprolactinemia. The control group animals were given saline in the same way. For light and electron microscopy the prostate dorsal lobes were obtained routinely. To evaluate the intensity of immunohistochemical reaction for AR in epithelial cells, the optical density was measured and computer-assisted image analysis system was used. Morphological observations of the dorsal lobe epithelial cells were carried out in transmission electron microscope. MCP caused over twofold increase in prolactin (PRL) serum levels. In rats with hyperprolactinemia, the testosterone levels (T) were twofold decreased. The intensity of immunohistochemical reaction for AR in epithelial cells of dorsal lobe in the experimental group was significantly lower than in the control group. In the dorsal lobe epithelial cells of experimental group animals, the transmission electron microscopy (TEM) revealed highly dilated RER cisternae and reduced number of microvilli on the cellular surface when compared to the control group. The results show that hyperprolactinemia in male rats causes morphological abnormalities in the dorsal lobe of prostate. The abnormalities are caused by elevated prolactin either directly or indirectly through decreased level of testosterone. Decreased expression of AR in epithelial cells of prostate dorsal lobe is likely to be caused by decreased testosterone level
Provenance Management over Linked Data Streams
Provenance describes how results are produced starting from data sources, curation, recovery, intermediate processing, to the final results. Provenance has been applied to solve many problems and in particular to understand how errors are propagated in large-scale environments such as Internet of Things, Smart Cities. In fact, in such environments operations on data are often performed by multiple uncoordinated parties, each potentially introducing or propagating errors. These errors cause uncertainty of the overall data analytics process that is further amplified when many data sources are combined and errors get propagated across multiple parties. The ability to properly identify how such errors influence the results is crucial to assess the quality of the results. This problem becomes even more challenging in the case of Linked Data Streams, where data is dynamic and often incomplete. In this paper, we introduce methods to compute provenance over Linked Data Streams. More specifically, we propose provenance management techniques to compute provenance of continuous queries executed over complete Linked Data streams. Unlike traditional provenance management techniques, which are applied on static data, we focus strictly on the dynamicity and heterogeneity of Linked Data streams. Specifically, in this paper we describe: i) means to deliver a dynamic provenance trace of the results to the user, ii) a system capable to execute queries over dynamic Linked Data and compute provenance of these queries, and iii) an empirical evaluation of our approach using real-world datasets
Potencial alelop?tico de Arachis hypogaea sobre a germina??o de plantas daninhas
Allelopathy can be combined with crop rotation, reducing the cost of producing weed
control, as it enables a more sustainable and environmentally friendly management,
reducing the risk of resistance compared to control strategies based only on herbicide
use. Brazil has great potential for peanut production, and the crop can increase the
value added per productive area, benefiting the next crops, being an ideal plant for
effective crop rotation. The present work aimed to analyze the allelopathic potential of
the almond tree (Arachis hypogaea) on the germination of Ipomoea grandifolia, Euphorbia heterophylla, Bidens pilosa, and Digitaria insularis seeds. The experimental
design was completely randomized consisting of 4 weed species and 4 concentrations
of raw aqueous extract of almond (0%, 1%, 5% and 10%), with a total of three replications. The final germination percentage on the tenth day of the experiment and the
germination velocity index (GVI) were evaluated. The almond extracts with 5% and 10%
presented allelopathic potential in all studied species, decreasing the germination averages and the number of germinated seeds each day.A alelopatia pode ser aliada a rota??o de culturas, diminuindo do custo de produ??o
do controle de plantas daninhas, pois possibilita uma forma de manejo mais
sustent?vel e ecol?gica diminuindo o risco de resist?ncia em compara??o com
estrat?gias de controle baseados apenas no uso de herbicidas. O Brasil apresenta
grande potencial para a produ??o de amendoim, e a cultura pode aumentar o valor
agregado por ?rea produtiva, beneficiando os pr?ximos cultivos, sendo uma planta
ideal para uma efetiva rota??o de culturas. O presente trabalho teve como objetivo
analisar potencial alelop?tico do amendoeiro (Arachis hypogaea) sobre a germina??o
de sementes de Ipomoea grandifolia, Euphorbia heterophylla, Bidens pilosa, e
Digitaria insularis. O delineamento experimental foi o inteiramente casualisado
constitu?do por 4 esp?cies de plantas daninhas e 4 concentra??es de extrato aquoso
bruto de amendoeiro (0%, 1%, 5% e 10%), sendo realizadas um total de tr?s
repeti??es. Foram avaliados o percentual de germina??o final ao d?cimo dia do
experimento e o ?ndice de velocidade de germina??o (IVG). Os extratos de
amendoeiro com 5% e 10% apresentaram potencial alelop?tico sobre todas as
esp?cies estudadas, diminuindo as m?dias de germina??o e o n?mero de sementes
germinadas a cada dia
The expression of androgen receptors in the epithelial cells of the rat prostate lateral lobe in experimental hyperprolactinaemia: a morphological and immunohistochemical study
The effect of hyperprolactinaemia on the prostate has still not been fully elucidated.
The aim of the study was to estimate the influence of hyperprolactinaemia
on expression of the androgen receptor (AR) in rat epithelial cells of the
prostate lateral lobe and on the morphology of these cells. Studies were performed
on sexually mature male Wistar rats. To provoke hyperprolactinaemia
rats received i.p. metoclopramid (MCP). For light and electron microscopy the
lateral lobes were obtained routinely. The intensity of the immunohistochemical
reaction of AR (expression of AR) in the epithelial cells of the prostate lateral
lobe was assessed by optical density measurements with the help of computer
image analysis. Ultrastructural observations of the epithelial cells of the lateral
lobe were carried out by means of transmission and scanning electron microscopes.
The results showed a more than twofold increase in prolactin (PRL) concentration
in the serum, but a twofold decrease in testosterone (T). The intensity
of the immunohistochemical reaction of AR in the epithelial cells of the lateral
lobe in the experimental group was higher than in the control group. We noted
changes in the morphology of the epithelial cells of the prostate lateral lobe in
the experimental group
Morphological, histochemical and immunohistochemical studies of polar fox kidney
The aim of the present study was to evaluate the morphology and intermediate filaments cytokeratin, desmin and vimentin expression in the kidneys of the polar fox (Alopex lagopus). Routine morphological, histochemical and immunohistochemical techniques of examinations of the kidneys of adult male and female polar foxes were used. We found different localizations and different levels of immunoexpression of cytokeratin in epithelia of calyxes, distal tubules and Henle’s loops, and also in endothelial cells. We also noted immunolocalization and immunoexpression of vimentin in mesangial cells, interstitial tissue and distal tubules. Desmin reactivity was revealed for muscle cells of arteries and mesangial cells. Our study is the first attempt to localize cytoskeletal intermediate filaments performed on polar fox kidneys. It is worth noting that our observations concerning the distribution of vimentin in the polar fox kidney may suggest that protein as being useful as a marker of distal tubules in the polar fox kidney
Morphological and immunohistochemical comparison of three rat prostate lobes (lateral, dorsal and ventral) in experimental hyperprolactinemia.
The prolactin plays an important role in the regulation of growth and differentiation of prostate gland besides androgens. The goal of this study was to reveal the influence of elevated prolactin concentration on epithelial cells of prostate. We compared the morphology of epithelial cells of prostate dorsal, lateral and ventral lobes and expression of androgen receptors in these cells in rats with hyperprolactinemia and in control rats. We used sexually mature male Wistar rats. The experimental rats received metoclopramide; the control group received saline in the same way. The prostate dorsal, lateral and ventral lobes were collected routinely for light and electron microscopy. The intensity of immunohistochemical reaction of androgen receptor in epithelial cells of dorsal, lateral and ventral lobes was evaluated by measure of optical density with computer image analysis. The light and electron (transmission and scanning) microscopes were used for morphological observations. Results: In experimental rats twofold increase in prolactin and twofold decrease in testosterone found. In experimental group the expression of androgen receptor was lower in columnar epithelial cells of dorsal and ventral lobes but higher in lateral one. We observed morphological abnormalities in columnar epithelial cells of lateral and dorsal lobes. The columnar epithelial cells of ventral lobes didn't show any morphological changes in hyperprolactinemia
