Melancolía en la poesía andina: «Himno a Manko Kapac»
No full textMelancholy is part of the soul of the human being. It is projected in any vital women and men areas of the culture, especially in the field of literature. Western melancholy has been deeply studied and profusely analyzed, but the same has not happened with Andean melancholy. After the Conquest of America by the Spanish conquerors, the Andean soul fell in a lake of sadness. In this paper we try to show the brightness of the Andean heart. The selection of the poem «Hymn to Manko Kapac» is a homage to Peruvian indigenous culture. The intrinsic melancholy, many centuries later, will give wings to the creative talent of the brilliant poet César Vallejo. The wonderful poetry of this author continues the line shown by its predecessors: the first Andean poets who wrote «Hymn to Manko Kapac». Key words: Andean culture, poetry, indigenism, Manko Kapac, melancholy.La melancolía forma parte de la esencia del ser humano. Se ve proyectada en todas las áreas vitales de las mujeres y los hombres, especialmente, en el campo de la literatura. La melancolía occidental ha sido profusamente estudiada y analizada. Pero no ocurre lo mismo con la melancolía andina. Tras la conquista de América a manos de los españoles primero y los europeos después, el alma andina, ya de por sí melancólica, se fue sumiendo en una mayor tristeza. El objetivo de este trabajo es el de resaltar y dar cabida a la melancolía del alma andina y subrayar el aliento creativo del que manarán posteriores creaciones artísticas. La metodología a seguir es el uso de las herramientas que nos aporta la especialidad académica de la teoría de la Literatura y la Literatura Comparada. La elección del poema «Himno a Manko Kapac» es un homenaje al mundo indígena peruano. Esa melancolía intrínseca que dio lugar a este poema, muchos siglos después otorgará las alas al talento creador del genial poeta César Vallejo. La maravillosa poesía de este autor sigue la línea marcada por sus antecesores: los primeros poetas andinos autores de «Himno de Manko Kapac».Palabras clave: cultura andina, poesía, indigenismo, Manko Kapac, melancolía

Gonocoxal condyles apparently fused with parameral sheath. Gonopods see Figs 28, 29. Gonocoxites are almost cylindrical, stout, as long as gonostyli, at first of the same width, then rapidly tapering to the conspicuously sclerotized prolonged tips (Fig. 29). Gonocoxites have two long setae on the inner side basally, hardly as long as phallomeres. Epandrium (Figs 35, 36) quadrate with two patches of hairs on both sides caudally and a deep notch distally.

In the new species, the two parameral sclerites are not pointed; they are blunt and separated distally. The gonostyli are at first almost globular (swollen) and bent in almost right angle to very prolonged, thin, needle-shaped protuberances. P. inopinata has two parameral sclerites tapering and touched caudally in one point, and the gonostyli are, moreover, at first cylindrical at first and then rapidly tapering to the conspicuously sclerotized prolonged tips, almost straight or only a little arched (Fig. 29).

Revised research about chaotic dynamics in Manko et al spacetime
No full textA recent work by Dubeibe et al. [Phys. Rev. D 75, 023008 (2007)] stated that chaos phenomenon of test particles in gravitational field of rotating neutron stars which are described by Manko, Sanabria-Gomez, and Manko (Manko et al.) metric can only occur when the stars have oblate deformation. But the chaotic motions they found are limited in a very narrow zone which is very close to the center of the massive bodies. This paper argues that this is impossible because the region is actually inside of the stars, so the motions cannot exist at this place. In this paper, we scan all parameters space and find chaos and unstable fixed points outside of stars with big mass-quadrupole moments. The calculations show that chaos can only occur when the stars have prolate deformation. Because real deformation of stars should be oblate, all orbits of test particles around the rotating neutron stars described by Manko et al. solutions are regular. The case of nonzero dipolar magnetic moment has also been taken into account in this study
Geodesics and resonances of the Manko-Novikov spacetime
No full textThesis (MSc)--Stellenbosch University, 2013.ENGLISH ABSTRACT: In this thesis I study compact objects described by the Manko-Novikov spacetime. The Manko-
Novikov spacetime is an exact solution to the Einstein Field Equations that allows objects to be
black hole-like, but with a multipole structure di erent from Kerr black holes. The aim of the
research is to investigate whether we will observationally be able to tell these bumpy black holes,
if they exist, apart from traditional Kerr black holes. I explore the geodesic motion of a test
probe in the Manko-Novikov spacetime. I quantify the motion using Poincar e maps and rotation
curves. The Manko-Novikov spacetime admits regions with regular motion as well as regions with
chaotic motion. The occurrence of chaos is correlated with orbits for which the characteristic
frequencies are resonant. The new result presented in this thesis is a global characterisation
of where resonances and thus chaos are likely to occur for all orbits. These calculations are
performed in the Kerr spacetime, from which I obtain that low order resonances occur within
20 Schwarzschild radii (or 40M) of the compact object with mass M. By the KAM theorem,
the occurrence of chaos is therefore limited to this region for all small perturbations from Kerr.
These resonant events will be measurable in the Galactic Centre using eLISA. This con nement
of low order resonances indicates that the frequency values of orbits of radii well outside of
20 Schwarzschild radii can be approximated using canonical perturbation theory.AFRIKAANSE OPSOMMING: In hierdie tesis word kompakte voorwerpe bestudeer soos omskryf deur die Manko-Novikov
ruimtetyd. Die Manko-Novikov ruimtetyd is 'n eksakte oplossing van die Einstein Veldvergelykings.
Die Manko-Novikov ruimtetyd formuleer gravitasiekolk-tipe voorwerpe waarvan die
veelpool-struktuur afwyk van die tradisionele Kerr gravitasiekolk-struktuur. Die oogmerk van die
navorsing is om vas te stel of ons met behulp van waarnemings hierdie bonkige gravitasiekolke van
die tradisionele Kerr gravitasiekolke kan onderskei. Ek ondersoek die geodetiese beweging van 'n
toetsmassa in die Manko-Novikov ruimtetyd. Die beweging word gekwanti seer met behulp van
Poincar e afbeeldings en rotasiekrommes. In die Manko-Novikov ruimtetyd identi seer ek gebiede
waarbinne re elmatige beweging voorkom asook gebiede waarbinne chaotiese bane voorkom. Die
ontstaan van chaos word geassosieer met bane waarvan die fundamentele frekwensies resonant is.
'n Nuwe resultaat wat in hierdie tesis voorgehou word behels 'n globale karakterisering wat aandui
waar resonansies en dus chaos na alle waarskynlikheid voorkom. Laasgenoemde berekeninge
word vir die Kerr ruimtetyd uitgevoer. Hierdeur toon ek alle lae orde resonansies kom voor binne
20 Schwarzschild radii (of 40M) vanaf die kompakte voorwerp met mass M. Die KAM Stelling
bepaal dan dat vir alle klein steurings toegepas op die Kerr ruimtetyd die voorkoms van chaos
beperk sal wees tot bogenoemde gebied. Die resonansies binne hierdie gebied sal deur eLISA in
die sentrum van die melkwegstelsel gemeet kan word. Hierdie beperking van lae orde resonansies
tot 'n sekere afstand vanaf die kompakte voorwerp verseker dat die frekwensies van bane wat
buite hierdie gebied val, akkuraat deur kanoniese steuringsteorie bepaal kan word
