La comunicación de la verdad global a la persona con una enfermedad incurable: qué, cómo y por qué decirlo

Resumen: El encuentro de salud se da entre un ser humano doliente, que busca ayuda, y otro con capacidad técnica, que está en disposición de prestársela. La calidad de la comunicación influye en el paciente afectando la mejor comprensión de los problemas, en la adherencia terapéutica y en los resultados. Finalmente, es una herramienta básica para expresar en la práctica asistencial la información global al paciente, adaptando los conocimientos sanitarios a las características y contexto de cada uno. En la relación asistencial es tanto o más importante que lo que se dice el modo y la ocasión en que se dice. Sólo de esta forma el profesional de la salud estará preparado para comunicar una verdad global.

A possible alchemist apparatus from the early islamic period excavated at Ramla, Israel

Abstract: During extensive salvage excavations carried out during the years 2004-2008 in a large Early Islamic industrial area at the vicinities of Ramla, in Central Israel, an unparalleled industrial device was unearthed. The star-shaped, soil embedded installation, whose lower part was preserved, consisted of a central pottery jar surrounded by five minor jars, linked by ceramic pipes. Evidence of heat was observed mainly around the central vessel, and metal hollow cones perforated in the tip were found inside the surrounding jars. Although the manufacturing procedures and operation techniques of the installation are not completely clear, it is proposed that the installation is part of an industrial workshop or an alchemy laboratory. Both industry and alchemy were well-developed during the Early Islamic period and very often closely related, to the point that sometimes it is difficult to distinguish between them. The identification proposed is based on comparisons with tools described in literary sources, and somewhat later drawings and etchings. Circumstantial ceramic evidence was found, as well as the proximity of a bathhouse whose guests could have been the consumers of perfumes and unguents seem to reinforce this possibility. Due to the poor state of preservation of the device and the lack of available comparisons, the identification proposed here is tentative, and future research coupled with eventual new discoveries is needed in order to clarify this matter.

Poner el cuerpo. Mujeres y política estatal en Mari (Siglo XVIII a.c.)

Women and men are subjects defined both by their physical-natural reality and their socio-cultural environment. In this way they are reified, and many such examples can be found throughout history. We are interested in the situation of women in Ancient Mesopotamia, particularly the daughters of Zimrî-Lîm, king of the city of Mari, the archaeological site of Tell Hariri, modern Syria, during the 18th century BC. Zimrî- Lîm made marriages a policy of the state. He himself married foreign women and married their joint daughters to other important kings as well. This marital policy was another, more extended, way of dominion where women were a nexus between Mari and other states. In this paper, we will analyze the roles which were assigned and developed by royal women from a political level via a comprehensive approach. These women are presented generally as political objects, though, in extreme cases also they were taking forward actions as subjects and by it they were visualized as “the other,” the foreigner and, in some cases, the enemy.

严格求解夹层圆柱壳在轴压下的轴对称失稳问题

本文在文献[1]的基础上,用严格的方法求解两端简支的夹层圆柱壳在均匀轴压下的轴对称失稳问题.内、外表层很薄弹性模量又大,按薄壳理论处理;夹心较厚弹性模量又相当小,横向剪切变形的影响必须考虑,在研究夹层壳的整体失稳尤其是局部失稳时,横向的拉伸和压缩变形也不可忽略,用数学弹性力学的方法处理.本文导得了可求解轴对称整体失稳和局部失稳临界载荷的超越方程,用数值计算的方法可算得临界载荷的最小值.对于整体失稳的情况,给出算例,与夹层壳理论的解作了比较.

The plastic instability behaviour of laser-textured steel sheet

As the production of a new technique that can offer both good formability and high image clarity for texturing metal sheet, laser-textured sheet has attracted the attention of many manufacturers and users. Among the many subjects to be studied, plastic instability behaviour of the laser-textured sheet is one of most important to understand its ability in extending material ductility and to appropriately control this technique. Experimental investigations are carried out in this paper to study the macroscopic behaviour and microstructural mechanism of the laser-textured sheet, and comparison is made with the normal sheet taken from the same coil of metal sheet. It is demonstrated that, the difference in the behaviour of plastic instability obviously shows tendency to delay strain localization and the onset of thickness necking. Shear banding and internal void damage are spread to a much wider region in the sheet being laser-textured. The prestrained microcraters enforced on the surface of the textured sheet act as hardening spots, which are likely to share out deformation and inhibit the increasing rate of voiding, and eventually favouring the ductility of the material used.

The strange attractor of a kind of 2-dimensional map and dynamical properties on it

On the basis of previous works, the strange attractor in real physical systems is discussed. Louwerier attractor is used as an example to illustrate the geometric structure and dynamical properties of strange attractor. Then the strange attractor of a kind of two-dimensional map is analysed. Based on some conditions, it is proved that the closure of the unstable manifolds of hyberbolic fixed point of map is a strange attractor in real physical systems.

The influence of microcrack density on the elastic and fracture mechanical properties of stripa granite

Microcracks can have a strong influence on the elastic and fracture mechanical properties of rocks if they are numerous, or if they are orientated in unfavourable directions in anisotropic rocks in particular. This paper presents results from a great number of mechanical tests on Stripa granite containing various amounts of microcracks. Variations in the microcrack density were obtained by shock-heating the rock at different temperatures in the range 100–600°C for 3 h.
