Gabriel Varj?o Lima,Richard Halti Cabral,Danilo Leite Andrade,Nayara Soares de Oliveira Lacerda
International Journal of Morphology , 2012,
Abstract: Clinical and surgical importance of the levator scapulae muscle (LSM) requires a better knowledge of its anatomic variation mainly because of the possibility of new findings related to the embryologic development. This article reports a case of a left-sided LSM with atypical attachments in a 58-year-old preserved Caucasian female body. The muscle presented a bifurcation at its midpoint downward path. Its medial band attached to the anterior aspect of the left rhomboideus major muscle while its left band was fixed in the superior angle of the scapula after releasing a muscle expansion to the serratus anterior muscle. The morphometric analysis revealed LSM maximal width of 3.6 cm, bifurcation point located 6.6 cm apart from the C1 vertebral attachment; medial band legth of 5.7 cm and lateral band width of 2.1cm. Regarding anatomic variations of the LSM, they may remain unnoticed or perhaps contribute for pathologic conditions of the neck and the back. Debido a la importancia clínica y quirúrgica del músculo elevador de la escápula, se hace necesario conocer mejor sus variaciones, principalmente la posibilidad de encontrar hallazgos relacionados con su desarrollo embriológico. Se presenta el caso de un músculo elevador de la escápula del lado izquierdo encontrado en un cadáver de sexo femenino de 58 a os. El músculo elevador de la escáula presentaba una bifurcación en el punto medio en su trayectoria más baja. La banda medial se fijaba en la parte anterior del músculo romboides mayor izquierdo; mientras que su banda lateral se fijaba en el ángulo superior de la escápula después de enviar una expansión hasta el músculo serrato anterior. El análisis morfométrico reveló un ancho máximo de 3,6 cm, punto de bifurcación situado 6,6 cm bajo la inserción vertebral C1; longitudes de la banda medial 5,7 cm y lateral de 2,1cm. Las variaciones anatómicas del músculo elevador de la escápula pueden pasar inadvertidas, pero también pueden contribuir con algunas condiciones patológicas del cuello y espalda.
Love as Attunement  [PDF]
Acylene Maria Cabral Ferreira
Open Journal of Philosophy (OJPP) , 2018, DOI: 10.4236/ojpp.2018.82008
Abstract: We aim to show, using Being and Time and Zollikon Seminars, that solicitude (Fürsorge) as the disclosedness of being-with is the condition of possibility for the existential-ontological constitution of the attunement of love. Centered on the text On the Essence of Truth, our purpose is to emphasize that freedom is also an attunement. Our hypothesis is that the copertinence of love (the fundamental disclosedness to the other) and of freedom (the letting-be of the other) consists in a modification of the existential of disposedness (Befindlichkeit) and expresses the unity and ontological circularity of being-in-the-world.
The Mind-Body Problem Today  [PDF]
Gabriel Vacariu
Open Journal of Philosophy (OJPP) , 2011, DOI: 10.4236/ojpp.2011.11005
Abstract: An old philosophical problem, the mind-body problem, has not been yet solved by philosophers or scientists. Even if in cognitive neuroscience has been a stunning development in the last 20 years, the mind-body problem remained unsolved. Even if the majority of researchers in this domain accept the identity theory from an ontological viewpoint, many of them reject this position from an epistemological viewpoint. In this context, I consider that it is quite possible the framework of this problem to be wrong and this is the main reason the problem could not be solved. I offer an alternative, the epistemologically different worlds perspective, that replace the world or the universe. In this new context, the mind-body problem becomes a pseudo-problem.
Analysis of Dynamics Fields in Noninertial Systems  [PDF]
Gabriel Barceló
World Journal of Mechanics (WJM) , 2012, DOI: 10.4236/wjm.2012.23021
Abstract: In this paper, I present evidence that there exists an unstructured area in the present general assumptions of classical mechanics, especially in case of rigid bodies exposed to simultaneous noncoaxial rotations. To address this, I propose dynamics hypotheses that lead to interesting results and numerous noteworthy scientific and technological applications. I constructed a new mathematical model in rotational field dynamics, and through this model, results based on a rational interpretation of the superposition of motions caused by torques were obtained. For this purpose, I analyze velocity and acceleration fields that are generated in an object with intrinsic angular momentum, and assessed new criteria for coupling velocities. In this context, I will discuss reactions and inertial fields that cannot be explained by classical mechanics. The experiments have been analyzed and explained in a video accompanying this text. I am not aware of any concurrent study on the subject and conclusions evidenced in this paper, preventing us from making additional theoretical com- parisons or indicate to the reader other sources to compare criteria.
Proposal of New Criteria for Celestial Mechanics  [PDF]
Gabriel Barceló
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.34044
Abstract:

Based on a new interpretation on the behavior of rigid bodies exposed to simultaneous non-coaxial rotations, we have developed a hypothesis: the Theory of Dynamics Interactions, which can be applied to understand celestial mechanics. We have analyzed the velocity and acceleration fields generated in a rigid body with intrinsic angular momentum, when exposed to successive torques, to assess new criteria for this speeds coupling. In this context, reactions and inertial fields take place, which cannot be justified by means of classical mechanics. We believe that the results obtained after the analysis of dynamics fields systems accelerated by rotation will allow us to conceive a new perspective in celestial dynamics, astrometry, stellar dynamics and galactic astronomy, unknown up to date. After carrying out ample research, we have come to the conclusion that there still exists an unstructured scientific area under the present general assumptions and, more specifically, in the area of dynamic systems submitted to rotational accelerations. The aim of this paper is to present information of the surprising results obtained, and to attract the interest towards the investigation of this new area of knowledge in rotational non-inertial dynamics, and its multiple and remarkable scientific applications.

YintelligenceTM: The Mapping of the Pre-Heaven or FuXi Hexagrams to the Post-Heaven or King Wen Hexagrams  [PDF]
Gabriel Felley
Chinese Studies (ChnStd) , 2013, DOI: 10.4236/chnstd.2013.24032
Abstract: The Yijing易經belongs to the famous group of the five classics. In the Ming and Qing dynasties, the Four Books and Five Classics四書五經 were the subject of mandatory study by those Confucian scholars who wished to become government officials. The Yijing (Faure & Javary, 2002) consists of 64 figures called hexagrams 卦 formed by six Yin (broken) or Yang (unbroken) lines and commentaries on each of these hexagrams and their lines. The whole set of the hexagrams and their interdependencies make a dynamic model for the understanding or the anticipating of the different steps change goes through. The Yijing does not predict the future but gives a snap-shot of the actual situation and the holistic potentialities which may be deployed or not in order to better adapt to the on-going change. The different stages of a change are explained by the Yin-Yang polarity and the never-ending transformation of old-Yin 老陰in young-Yang少陽, old-Yang老陽, young-Yin少陰 and old-Yin again. The 64 hexagrams are built by pairing the 8 basic trigrams obtained by adding to each bigram a supplementary Yin or Yang line. Figure 1 depicts a 4-regions space (East/young Yang, South /old Yang, West/young Yin, North/old Yin) and a cyclic movement. A forthcoming article will explain the relation between this space organization and the whole set of 64 hexagrams as a network. The cyclic change is of major interest. Purpose: The 64 hexagrams of the Yijing are organized in 16 “first degree” nuclear families (Javary, 1997), which may be consolidated in 4 “second degree” nuclear families. There are another 16 families organizing the 64 hexagrams in a different structure. In the literature they are called the pre-heaven先天 hexagrams (Schlumberger, 1987), and in this paper they are referred to as the FuXi伏羲 hexagrams. They form 16 cyclic families, whose structure will be analyzed in this paper. This cyclicity induces a “predecessor-successor” relationship between the hexagrams belonging to the same FuXi family: H1H2H3H4H1. While the 4 members of each nuclear family are centered on a “master” hexagram that corresponds to a common inner lines’ structure, each FuXi family is cyclically structured and we call the hexagrams belonging to the
Theory of Dynamic Interactions: The Flight of the Boomerang  [PDF]
Gabriel Barceló
Journal of Applied Mathematics and Physics (JAMP) , 2014, DOI: 10.4236/jamp.2014.27063
Abstract:

We propose a new interpretation of the dynamic behavior of the boomerang and, in general, of the rigid bodies exposed to simultaneous non-coaxial rotations. We have developed a new rotational non-inertial dynamics hypothesis, which can be applied to understand both the flight of the boomerang as well as celestial mechanics. The boomerang is a particularly significant, intriguing and widely known case of bodies in rotation. We have analyzed the velocity and acceleration fields generated when rigid bodies are exposed to successive torques, in order to assess new criteria for this speed coupling. In this context, reactions and inertial fields that cannot be justified by means of classical mechanics take place. Accordingly, we propose a new Theory of Dynamic Interactions. We believe that the results obtained will enable us to conceive a new perspective in dynamics, unknown to date. After carrying out ample research, we have come to the conclusion that there still exists an unstructured scientific area in non-inertial dynamics systems subject to rotational accelerations. The aim of this paper is to present information of the surprising results obtained and to attract interest in research into dynamic field systems accelerated by rotation, and the multiple and remarkable scientific applications arising thereof. We further propose the boomerang as a clear example of the application of the Theory of Dynamic Interactions.

Common Factors in International Bond Returns and a Joint ATSM to Match Them  [PDF]
Christian Gabriel
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.47067
Abstract:

The existence of common factors in international bond markets is an important cause for modelling different term structures of interest rates jointly. This paper investigates the common factors of US and UK treasury yields in the period of 1983 to 2012. A principal component analysis motivates the type of joint ATSM for modelling the yield curves of two distinct economies. In sum, two common factors explain 85% of the yield variation and the model factors have a solid economic intuition.
