1. Entradas e saídas de uma cultura de violência - “A fita branca” e “O desertor”: duas representações fílmico-literárias no mundo de língua alemã
Resumo: Dois filmes mostram os enormes desafios morais e políticos da memória na Alemanha da primeira metade do século XX, nos quais não só o indivíduo, mas também a sociedade como um todo foram expostos à capacidade de julgar com independência e humanidade. O primeiro filme é “The white ribbon” (Michael Haneke, 2009), que se passa no início d

2. De (re)conto e (des)encanto: uma leitura de Fita verde no cabelo
Resumo Fita verde no cabelo: nova velha história, conto de Guimarães Rosa, apresenta uma leitura de Chapeuzinho Vermelho. Como indica o subtítulo - nova velha história -, a narrativa rosiana ressignifica as versões tradicionais de Chapeuzinho, projetando a história em meio à perplexidade do mundo contemporâneo, desconstruindo certezas, deslocando fan

3. Microtensile bond strength of root canal dentin treated with adhesive and fiber-reinforced post systems
Abstract Nowadays, demand for esthetic restorations has risen considerably; thus, nonmetal esthetic posts made of either high-strength ceramics or reinforced resins, such as fiber-reinforced resin posts, have become more and more popular. Important characteristics of fiber-reinforced posts involve a modulus of elasticity similar to dentin and their ability t

4. Protein and mRNA expression of gonadotropin-releasing hormone receptor in yaks during estrus
ABSTRACT To demonstrate the role of gonadotropin-releasing hormone (GnRH) in yaks (Bos grunniens), we characterized the expression of gonadotropin-releasing hormone receptor (GnRHR) mRNA and protein. The level of GnRHR mRNA in the hypothalamus was higher than that in the pineal gland, pituitary gland, and ovary during estrus. Immunofluorescence analysis show

5. Study on Magnetic Behavior of Nd8Fe84Ti2B6 Nanocomposite by FORC Diagram
Systematic investigation was made on the magnetic property of a series of Nd2Fe14B/α-Fe nanocomposites prepared by crystallization of amorphous Nd8Fe84Ti2B6 ribbon at annealing temperatures in the range of 800-860 °C. Both remanence and energy product increase with increasing annealing temperature, reaching the maximum values at 850 °C. Coercivity remains

6. Syntheses and Fundamental Properties of Fe-rich Metastable Phase Alloys with Saturation Magnetization Exceeding 1.9 T
A melt-spun Fe90Si5B5 alloy ribbon consists of bcc-Fe(Si) + Fe3B + amorphous phase and exhibits good bending ductility, high tensile fracture strength above 1000 MPa, high corrosion resistance and unique magnetic properties as exemplified for high saturation magnetization exceeding 1.9 T, moderately high initial permeability of about 150 and low coercivity o

7. Protein and mRNA expression of estradiol receptors during estrus in yaks (Bos grunniens)
ABSTRACTThe objective of this study was to investigate mRNA by real-time PCR and protein expression by immunofluorescence of the estradiol receptors (ER) in the pineal gland, hypothalamus, pituitary gland, and gonads of yaks (Bos grunniens). The analysis showed that the level of expression of ER mRNA was greater in the pituitary gland tissue than in other gl

8. Generalizating path and fan graphs: subcoloring and toughness
Two graph classes are presented; the first one (k-ribbon) generalizes the path graph and the second one (k-fan) generalizes the fan graph. We prove that they are subclasses of chordal graphs and so they share the same structural properties of this class. The solution of two problems are presented: the determination of the subchromatic number and the determin

9. Synthesis of Cu xO(x = 1,2)/amorphous compounds by dealloying and spontaneous oxidation method
Cu xO(x = 1,2)/amorphous compounds have been successfully synthesized by chemical free dealloying and spontaneous oxidation method. Technological parameters, such as the acid concentration and dealloying time strongly influence the crystal type, size and morphology of coppery oxide. The further study shows that with the increase of HCl concentration, the sur

10. Occurrence of Defects in Laser Beam Welded Al-Cu-Li Sheets with T-Joint Configuration
Abstract: In the aerospace industry, laser beam welding has been considered as one of the most promising routes among the new manufacturing processes. Substitution of riveting by laser beam welding of aircraft structures has contributed to weight and cost savings. Concurrently, new aluminum alloys have been developed with the addition of lithium with better

11. Synaptic vesicle cycling is not impaired in a glutamatergic and a cholinergic synapse that exhibit deficits in acidification and filling
O objetivo do presente trabalho foi investigar o tráfego de vesículas sinápticas quando estas apresentam alterações no armazenamento de neurotransmissores e acidificação em duas distintas sinapses: a junção neuromuscular colinérgica de rãs versus o terminal nervoso glutamatérgico do tipo ribbon em céulas bipolares da retina. Essas sinapses exibe

12. Aspectos eletrônicos e estruturais do grafeno e derivados:: um estudo teórico-experimental
In this work we study the electronic and structural properties of graphene and graphene based materials by means of experimental and theoretical techniques. By means of ab-initio calculations using the Density Funcional Theory (DFT), we study the effect of pressure on graphene multi-layers. We look for an explanation for experimental results on the charge in
