The pottery from A and C-Group tombs at Serra West in the Museum of Natural History, La Plata

Abstract: The Museum of Natural History, La Plata, Argentina, houses a ceramic collection of the A-Group and C-Group cultures from Nubian tombs at Serra West (AA and ACS cemeteries), on the west bank of the Nile in Lower Nubia. It has been originated from the division after the excavations made by the Franco-Argentine Archaeological Expedition in Sudan between 1961 and 1963, as part of the UNESCO campaigns to save the Nubian monuments.

Rafael Pividal y Alberto Duhau : aportes y debates en torno a la idea de democracia en el pensamiento político de intelectuales católicos

Resumen: A finales de la década del treinta, especialmente luego de la visita de Maritain en 1936 a la Argentina, surgieron con mucha fuerza una serie de debates dentro de los círculos intelectuales católicos argentinos. Uno de los temas tratados, entre otros, fue el valor de la democracia y, especialmente, su posible justificación como sistema político y su concordancia con las enseñanzas de la Iglesia. Sin embargo, aun aquellos que defendían la democracia no representaban un grupo homogéneo: tanto las fuentes intelectuales a las que recurrían como los fundamentos antropológicos de sus argumentaciones eran diversas. El presente artículo se propone desarrollar la defensa de la democracia que hicieron R. Pividal y A. Duhau, dos de estos intelectuales católicos. Como intentaré demostrar, aun cuando coinciden en resaltar el valor de la democracia y su plena concordancia con el catolicismo, la recurrencia a autores diversos (Maritain y a través de él la oposición a Maurras y Rousseau en un caso y Adam Smith y el Liberalismo escocés en el otro) generan que las argumentaciones de uno y otro difícilmente coincidan en mucho más que en esa positiva valoración que hacen del sistema democrático.

Derivation Of A Nonlinear Reynolds Stress Model Using Renormalization Group Analysis And Two-Scale Expansion Technique

Adopting Yoshizawa's two-scale expansion technique, the fluctuating field is expanded around the isotropic field. The renormalization group method is applied for calculating the covariance of the fluctuating field at the lower order expansion. A nonlinear Reynolds stress model is derived and the turbulent constants inside are evaluated analytically. Compared with the two-scale direct interaction approximation analysis for turbulent shear flows proposed by Yoshizawa, the calculation is much more simple. The analytical model presented here is close to the Speziale model, which is widely applied in the numerical simulations for the complex turbulent flows.

The vector fields admitting one-parameter spatial symmetry group and their reduction

For a n-dimensional vector fields preserving some n-form, the following conclusion is reached by the method of Lie group. That is, if it admits an one-parameter, n-form preserving symmetry group, a transformation independent of the vector field is constructed explicitly, which can reduce not only dimesion of the vector field by one, but also make the reduced vector field preserve the corresponding ( n - 1)-form. In partic ular, while n = 3, an important result can be directly got which is given by Me,ie and Wiggins in 1994.

Hannah Arendt y Walter Benjamin : masa, multitud, populacho

Resumen: Hannah Arendt y Walter Benjamin examinan los fenómenos asociativos de masa, multitud y populacho. Ambos sustraen tales grupos del ámbito político y los sitúan en el ámbito social. En Los orígenes del totalitarismo, Arendt indaga la noción de populacho o mob en el contexto del fenómeno imperialista. Asocia el carácter del populacho con el de la clase burguesa y posiciona ambos grupos en la emergencia de los nacionalismos tribales, ambos antecesores del totalitarismo. La masa es consustancial con los regímenes totalitarios. La apatía cívica, el cinismo y el derrumbe de las costumbres burguesas no alcanzan para explicar el fenómeno totalitario. El hombre masa ha perdido incluso el interés por sí mismo y el gusto por las asociaciones no partidarias. Walter Benjamin reflexiona literariamente los fenómenos de la bohème y de la multitud (crowd), a través de la poesía de Baudelaire y los relatos de Poe. El primer grupo incluye los conspiradores profesionales, cuyo aislamiento y resentimiento los emparenta con los miembros del mob. La falta de pertenencia y la ausencia de vínculos los conduce al activismo, sin un programa de acción. En el contexto de su reflexión sobre el fenómeno de la multitud, Benjamin indaga el impacto de las condiciones de vida moderna en las conductas automatizadas de los individuos. Los comportamientos reflejos, las respuestas automatizadas y los clichés, son las notas que también Arendt encuentra en el hombre “normal” y diluido en la masa, como lo evidenció la conducta de Eichmann durante el proceso en Jerusalén

Local exchange in the southern levant during the early bronze age: a political economy viewpoint

Trade and relations between the southern Levant and other regions of the Near East (mainly Egypt) during the Early Bronze Age (ca. 3,600–2,300 BC) have been the subject of many studies. Research concerning the exchange of local commodities was almost ignored or was discussed in parochial studies, focusing on specific archaeological finds. It is the intention of this paper to present the results of recent research of the exchange of commodities provided by archaeological data from excavations in the Southern Levant with regard to economic theories on the exchange-value of goods and exchange networks. Conclusions regarding the type of society and the forms of government in the Southern Levant during the Early Bronze Age are also presented.

Renormalization group approach on nanostructured systems

The electronic spectra of one-dimensional nanostructured systems are calculated within the pure hopping model on the tight-binding Hamiltonian. By means of the renormalization group Green's function method, the dependence of the density of states on the distributions of nanoscaled grains and the changes of values of hopping integrals in nanostructured systems are studied. It is found that the frequency shifts are dependent rather on the changes of the hopping integrals at nanoscaled grains than the distribution of nanoscaled grains.

The Droplet Group Micro-Explosions, Viscosity and Atomization Characteristics of W/O Emulsions

The spray of emulsified fuel, composed of diesel fuel, water and methanol can make micro-explosion under high temperature conditions, and the viscosity and the atomization characteristics of emulsion have significant effects on the micro- explosion of emulsions. To clarify the combustion mechanism of water-in-oil emulsion sprays, combustion bomb experiments were carried out, and the droplet group micro- explosions in W/O fuel emulsion sprays in a high-pressure, high-temperature bomb were observed clearly by a multi-pulsed, off-axis, image-plane ruby laser holocamera and continuously by a high-speed CCD camera.The viscosity and atomization characteristics of emulsions were also studied experimentally. The experimental results show that the higher concentration of the aqueous phase (water-methanol) (<50%) increases the viscosity of the emulsions, especially for higher agent concentration, and higher aqueous phase concentration and higher viscosity results in lager Sauter Mean Diameter (SMD). The experiment results also show that the different kinds of emulsifying agents, with different Hydrophile-Lipophile Balance (HLB) values, have significant influence on the viscosity of the emulsions.

The Grimsby Institute Group: Making it easy for students to use their own devices to learn

The Grimsby Institute wanted to create an infrastructure that would enable staff and students to use more mobile technology to enhance learning. They have improved the wifi connectivity in college and streamlined the software used to access college areas, as well as encouraging individuals to use their own technology. So far this has had a positive impact on retention and simplified the support that the college needs to provide, as well as saving the organisation money through some strategic changes.

Review of selected organisational IDs and development of use cases for the Jisc CASRAI-UK Organisational Identifiers Working Group

This project aimed to investigate and review candidates for providing an authoritative, widely used unique identifier for organisations involved in research in the UK. Specifically, we undertook to: ● clarify a representative but not comprehensive set of use cases for the UK research community to use organisational identifiers (orgIDs); ● survey and interview a small number of well-informed people in the field in order to create and prioritise a list of desirable features for the provision of orgIDs and potential services built around them; ● check the use cases and these required features against four possible candidate orgIDs and their providers; ● inform the Working Group of our conclusions and, if appropriate, make recommendations for adoption by the UK research community.
