Sonho e cura: o culto de Asclépio em Epidauro entre os séculos IV e II a. C.

Profound changes have marked Greek society from the fourth century B.C.. Conquests, wars and epidemics altered drastically the Greek’s posture regarding his public life, his conception of gods and hence the construction of their spaces, whether sacred or profane. Through the fonts, we perceived that the cult of god Asklepeios turned very popular, in this context, for the peculiar way that the god relates to his devotees, through the dreams. We know that the dream was held, for the Greeks, as a space of real existence, it was sacred, and could be accessed in the healing rituals of Asklepios. Our work intends, thereby, to understand the curious and peculiar oniric space, mainly through the inscriptions, architectural structures of the sanctuary and the ancient texts that refer to the context of the period, because we understand that this space was the essential condition for the popularization of the cult, it placed the individual in direct contact with the divinity, a rare closeness between men and gods accepted by the greek imagery until then.

Organometallic chemistry of diphosphazanes. Part 7. Platinum(II), palladium-(o), -(I) and -(II) complexes of RN[P(OPh)2]2(R = Me or Ph)

The reactions of [MCl2(cod)](M = Pd or Pt, cod = cycloocta-1,5-diene) with RN[P(OPh)2]2[R = Me (L1) or Ph (L2)] afford the chelate complexes [MCl2L1] and [MCl2L2]. The dinuclear palladium(O) complex, [Pd2L13] has been synthesized by starting from [Pd2(dba)3](dba = dibenzylideneacetone). Redox condensation of [Pd2(dba)3] and [PdCl2(PhCN)2] in the presence of the diphosphazane ligands gives the dinuclear palladium(I) complexes [Pd2Cl2L12] and [Pd2Cl2L22]. The structures of the complexes have been deduced from 1H and 31P NMR spectroscopic data. Single-crystal X-ray diffraction studies confirm the structures of [Pd2L13] and [Pd2Cl2L22].

Two Novel Heterometallic Chains Featuring Mn-II and Na-I Ions in Trigonal-Prismatic Geometries Alternately Linked to Octahedral Mn-IV Ions: Synthesis, Structures, and Magnetic Behavior

Two new one-dimensional heterometallic complexes, Mn3Na(L)(4)(CH3CO2)(MeOH)(2)]-(ClO4)(2)center dot 3H(2)O (1), Mn3Na(L)(4)(CH3CH2CO2)-(MeOH)(2)](ClO4)(2)center dot 2MeOH center dot H2O (2) LH2 = 2-methyl-2-(2-pyridyl)propane-1,3-diol], have been synthesized and characterized by X-ray crystallography. Both complexes feature Mn-II and Na-I ions in trigonal-prismatic geometries that are linked to octahedral Mn-IV ions by alkoxy bridges. Variable-temperature direct- and alternating-current magnetic susceptibility data indicated a spin ground state of S = 11/2 for both complexes. Density functional theory calculations performed on 1 supported this conclusion.

Ru (II)-Catalyzed C-H Activation: Ketone-Directed Novel 1,4-Addition of Ortho C-H Bond to Maleimides

A 1,4-addition with the nucleophilic center generated at the ortho carbon atom of an aromatic ketone in the presence of the highly reactive alpha-C-H bond, using a directing group strategy, is presented. The reaction yields pharmaceutically useful 3-arylated succinimide derivatives. In order to gain understanding of this redox neutral reaction, despite the presence of copper acetate, and to substantiate the lack of Heck-type products, DFT calculations have been carried out.

Site-Selective Addition of Maleimide to Indole at the C-2 Position: Ru(II)-Catalyzed C-H Activation

Synthesis of 3-(indol-2-yl)succinimide derivatives is presented using a directing group strategy. Selective functionalization of C-2 in the presence of highly reactive C-3 in indole derivatives has been achieved. A conjugate addition product instead of Heck-type product has been brought about by careful selection of the alkene partner (maleimides and maleate esters) such that a beta-hydride elimination is avoided.

Hierbas Aromáticas, medicinales y condimentarias en Colombia : análisis del caso C.I. Organic Aromatic S.A. desde la perspectiva de la nueva economía institucional

Las hierbas aromáticas han tenido en la última década un auge mundial y su demanda cada vez se incrementa más. En Colombia la producción y exportación de estas hierbas viene en aumento. En los últimos 4 años la exportación colombiana creció en 142 por ciento y el principal país de destino fue Estados Unidos a donde se exporto el 74 por ciento de las hierbas aromáticas. En este momento la tendencia del mercado mundial, es hacia los productos orgánicos o limpios, así que algunos productores se han dedicado a buscar los mecanismos para generar producciones y procesos con certificados orgánicos, para acceder a los mercados demandantes. Estas certificaciones son bastante exigentes y requieren un cambio y adaptación de las organizaciones, además de una fuerte inversión económica. El objetivo general de este trabajo es estudiar por medio del caso de la empresa colombiana C.I. Organic Aromatic S.A. la forma de adaptación a la demanda creciente del nuevo mercado internacional de hierbas aromáticas. Se realiza un análisis estructural discreto para el sector y de estar forma comprender el marco general donde se mueve la empresa. Al igual, se describe la empresa y su funcionamiento, los puntos críticos de la misma y de las transacciones que realiza. La cadena del sector esta descrita en el trabajo, los principales actores son: los proveedores, los productores donde se diferencian los pequeños de los medianos y grandes (los grandes productores son los exportadores de la cadena), los importadores o mayoristas, los transformadores, los minoristas, supermercados o tiendas especializadas y por último el cliente final, que cada vez más busca este tipo de productos por salud. C.I. Organic Aromatic S.A., es una empresa dedicada a la producción 100 por ciento orgánica y exportación de hierbas aromáticas y culinarias. La empresa tiene certificación de producto 100 por orgánico, buenas prácticas de manejo y certificación ISO entre otros. Llevan 7 años de funcionamiento, pero con esta razón social trabajan desde 2012 cuando decidieron exportar directamente a Estados Unidos y convertirse en C.I. (comercializadora internacional). Para disminuir la incertidumbre se integran verticalmente hacia adelante, bajo la marca Exotic Organic Herbs, quienes están ubicados en Miami, para manejar la logística de la importación en Estados Unidos.

A modular approach to luminescent dinuclear ruthenium(II) and rhenium(I) complexes

A series of dinuclear (bipyridine)tricarbonylrhenium(I) and tris(bipyridine)ruthenium(II) complexes have been isolated and characterised, bridged by a flexible diamido ethylene glycol chain. A new stepwise synthetic pathway has been investigated to heterometallic complexes, with the rhenium(I) complexes exhibiting an unusual configuration and inequivalence of the metal centres potentially arising from a surprising hydrogen-bonding interaction between an Re–CO group and an amide proton in low-polarity solvents. This interaction appears to be broken by competing hydrogen-bonding species such as dihydrogen phosphate. This effect was not observed in the corresponding ruthenium(II) complexes, which showed very little interaction with anions. The photophysical characterisation shows that the inclusion of two ester/amide groups to the rhenium centre effectively quenches the fluorescence at room temperature. The ruthenium(II) complexes have considerably stronger fluorescence than the rhenium species, and are less affected by theinclusion of ester and amide groups to the 2,2'-bipyridine chelating group.
