Estudios Gerenciales , 2001,
Abstract: el trabajo de investigación realizado por los profesores juan antonio gudziol y andrés lópez de la universidad icesi pretende poner a disposición de los gerentes de las empresas grandes del valle del cauca, una serie de herramientas que les permitirán en el futuro evaluar su posición competitiva en el ámbito mundial en lo relativo a la gestión ambiental integral. los resultados de dichas evaluaciones periódicas servirán de guía para una mejor utilización de los recursos con que cuenta el país y en especial el departamento del valle del cauca. los resultados obtenidos en esta investigación son el punto de partida para evaluaciones futuras y reenfoques necesarios para mantener los niveles de competitividad de las industrias que utilicen este método propuesto.

Abstract: Este caso ilustra la decisión a la que se enfrenta una empresa colombiana de ingresar a un mercado con alto potencial, en el cual su participación es casi nula. Se analizan las condiciones de la empresa, el mercado y el entorno, como paso inicial para la toma de una decisión que le puede exigir un cambio radical en sus operaciones comerciales, logísticas y de producción.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0082216
Abstract: Background Niemann-Pick type C disease (NPC) is a rare autosomal recessive lipid storage disease characterized by progressive neurodegeneration. As only a few studies have been conducted on the impact of NPC on sensory systems, we used a mutant mouse model (NPC1?/?) to examine the effects of this disorder to morphologically distinct regions of the olfactory system, namely the olfactory epithelium (OE) and olfactory bulb (OB). Methodology/Principal findings For structural and functional analysis immunohistochemistry, electron microscopy, western blotting, and electrophysiology have been applied. For histochemistry and western blotting, we used antibodies against a series of neuronal and glia marker proteins, as well as macrophage markers. NPC1?/? animals present myelin-like lysosomal deposits in virtually all types of cells of the peripheral and central olfactory system. Especially supporting cells of the OE and central glia cells are affected, resulting in pronounced astrocytosis and microgliosis in the OB and other olfactory cortices. Up-regulation of Galectin-3, Cathepsin D and GFAP in the cortical layers of the OB underlines the critical role and location of the OB as a possible entrance gate for noxious substances. Unmyelinated olfactory afferents of the lamina propria seem less affected than ensheathing cells. Supporting the structural findings, electro-olfactometry of the olfactory mucosa suggests that NPC1?/? animals exhibit olfactory and trigeminal deficits. Conclusions/Significance Our data demonstrate a pronounced neurodegeneration and glia activation in the olfactory system of NPC1?/?, which is accompanied by sensory deficits.

Abstract: this case study illustrates the decision that a colombian company is faced with in venturing into a large potential market, on which it has a virtually non-existent market share. it provides an analysis of the company, market, and environment conditions as an initial step to make a decision that might call for a dramatic change in the commercial, logistic, and manufacturing operations of a company.
Nonsmooth Optimization Algorithms in Some Problems of Fracture Dynamics  [PDF]
V. V. Zozulya
Intelligent Information Management (IIM) , 2010, DOI: 10.4236/iim.2010.211073
Abstract: Mathematical statement of elastodynamic contact problem for cracked body with considering unilateral restrictions and friction of the crack faces is done in classical and weak forms. Different variational formulations of unilateral contact problems with friction based on boundary variational principle are considered. Nonsmooth optimization algorithms of Udzawa’s type for solution of unilateral contact problem with friction have been developed. Convergence of the proposed algorithms has been studied numerically.
Precessing Ball Solitons as Self-Organizing Systems during a Phase Transition in a Ferromagnet  [PDF]
V. V. Nietz
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.410A3010
Abstract:

Precessing ball solitons (PBS) in a ferromagnet during the first order phase transition is induced by a magnetic field directed along the axis of anisotropy, while the action of the periodic field perpendicular to the main magnetic field has been analyzed. Under these conditions, the characteristics of arising equilibrium PBS are uniquely determined by the frequency of the periodic field, but the solitons with other frequencies are impossible. For such structure, the entropy increase connected with dissipation is compensated by the decrease of the entropy due to the external periodic field. It is shown that the equilibrium PBS are essentially the “self-organizing systems” that can arise spotaneously in a metastable state of ferromagnet.

Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.610155
Abstract: Precessing ball solitons (PBS) in a ferromagnet during the first order phase transition induced by a magnetic field directed along the axis of anisotropy, while the additional action of high-frequency field perpendicular to the main magnetic field, are analyzed. It is shown that the spatial motion of solitons, associated with thermal fluctuations in the crystal, does not destroy the equilibrium of self-organized PBS.
Lα Line of Dark Positronium as a Nongravitational Detection of DM  [PDF]

Abstract: An attempt to predict the new atomic dark matter lines is done on the example of a dark lepton atom-positronium. Its Layman-alpha line with the energy near 3 GeV may be observable if the appropriate conditions are realized. For this we have studied a γ-ray excess in the center of our galaxy. In principle, this excess may be produced by the Lα line of a dark positronium in the medium with Compton scattering. The possibility of observations of an annihilation line (E~300 TeV) of dark positronium is also predicted. Other proposals to observe the atomic dark matter are shortly described. Besides, Hα line (1.3μ) of usual positronum must be observable in the direction on the center of our galaxy.
