1. CONTENDING DISCOURSES OF BLACK AUTOBIOGRAPHY: RESPECTABILITY, AUTHENTICITY, AND MASCULINITY
Summary After historicizing the politics of racial representation in the slave narrative, this article considers how race, gender, and class intersect historically in the autobiographical production of Black men in the United States. At the dawn of the Jim Crow era, Black autobiography conformed to a cultural politics of racial synecdoche, which avowed that

2. Analytic solutions of the Schrödinger equation with non-central generalized inverse quadratic Yukawa potential
Abstract This study presents the solutions of Schrödinger equation for the Non-Central Generalized Inverse Quadratic Yukawa Potential within the framework of Nikiforov-Uvarov. The radial and angular part of the Schrödinger equation are obtained using the method of variable separation. More so, the bound states energy eigenvalues and corresponding eigenfunc

3. Secondary Metabolites from an Infusion of Lippia gracilis Schauer Using the LC-DAD-SPE/NMR Hyphenation Technique
The genus Lippia comprises approximately 200 species of herbs, shrubs and small trees, distributed throughout the South and Central America and tropical Africa. The species Lippia gracilis Schauer is an endemic aromatic plant of the Brazilian Northeast normally found in the states of Bahia, Sergipe and Piauí. The traditional communities of Caatinga, a semi-

4. Triatomic molecules in two-dimensional layers
We found universal laws for the spectrum of two-dimensional three-body systems, composed by two identical particles and a distinct one (AAB). These universal laws appear when the potential range (r_0) is much smaller than the size of the system. In two dimensions this condition is formulated as (E2 is the two-body energy and ? is the reduced mass). The zero

5. Parametric sensitivity analysis for the helium dimers on a model potential
Potential parameters sensitivity analysis for helium unlike molecules, HeNe, HeAr, HeKr and HeXe is the subject of this work. Number of bound states these rare gas dimers can support, for different angular momentum, will be presented and discussed. The variable phase method, together with the Levinson's theorem, is used to explore the quantum scattering proc

6. Transporte e estados confinados de portadores de carga em nanoestruturas de grafeno / Transport and Confined States of charge carriers in Graphene Nanostructures
In this work we investigate the behavior of charge carriers in a graphene sheet subjected to a one-dimensional electrostatic potential U(x). At first we consider two coupled quantum wells potential. For this structure we calculate the energy spectrum for the bound states, as well as the probability density behavior for some particular states. Some results fo

7. Gas de Bose diluido fracamente confinado / Dilute Bose gas weakly confined
A critical study of atomic Bose-Einstein condensates (BECs) is presented. Taking as a starting point the physics of the free gas, we study the effect of weakly confining potentials. Two cases were studied in detail: i) an atomic gas in a finite square well potential with a few bound states; and ii) a system confined in two-dimensions by an isotropic harmonic

8. Interatomic coulombic decay: a short review
The transition process of the interatomic Coulombic decay (ICD), is an electronic radiationless transition process, driving molecular complexes or clusters to a doubly ionized final state. This process differs from the Auger effect, because it takes place from a neutral monomer after the absorption of a released amount energy of the neighboring monomer in th

9. Study of the interaction of mass A=8 nuclei with carbon target and of the capture reaction 8Li(p,y)9Be of astrophysical interest / Estudo da interação de núcleos de massa A=8 com alvo de carbono e da reação de captura 8Li(p,)9Be de interesse astrofísico
The measurements of the angular distributions for the elastic scatterings 12C(Li,Li) and 12C(8B,8B) reported in this work have been done in two laboratories. Those corresponding to the angular distributions for the elastic scattering 12C(8Li,8Li) were performed at two ene&ies, 20.6 MeV and 23.9 MeV, at the Pelletron Laboratory of the University of São Paulo

10. Geometria, Topologia e Elasticidade: aplicações a membranas e outros sistemas bidimensionais
Geometry, topology and elasticity are found in various branchs of physics and they play important roles in the understanding of many physical phenomena. In this work, we present three diferent systems where we can see such importance. First, a quantum neutral particle, constrained to move on a conical surface, is used as a toy model to explore bound states d

11. Função social da propriedade intelectual : o patrimonialismo autoralista em ontraste com o direito de acesso à cultura / Social function of intellectual property: the contrast between the copyright s patrimonialism and the right to access to culture
The current Brazilian Constitution inserts property rights in the list of those referred as fundamental rights and, at the same time, it determines that property tangible or intangible, corporal or intellectual - must fulfill a social function. Concomitantly, the text of the Constitution anticipates that access to culture is also a fundamental right, as well

12. EVALUATION OF RADIOLABELING OF ANNEXIN A5 WITH TECHNETIUM-99m: INFLUENCE OF THE LABELING METHODS ON PHYSICO-CHEMICAL AND BIOLOGICAL PROPERTIES OF THE COMPOUNDS / Avaliação da radiomarcação da anexina A5 com Tecnécio-99m: influência do método de marcação nas propriedades físicos-químicas e biológicas do composto
Annexin A5 (ANXA5) is an intracellular human protein of 36 kDa with high affinity for membrane-bound phosphatidylserine that is selectively exposed on the surface of cells undergoing apoptosis. Apoptosis is important in normal physiology and innumerous pathologic states. Clinical applications for ANXA5 imaging are being developed in oncology, organ transplan
