Hacerse cargo del cuidado de un familiar dependiente puede afectar negativamente a la salud del cuidador/a en su vida afectiva y laboral. Las repercusiones del cuidado informal preocupan a las diferentes administraciones y también a los profesionales sanitarios, quienes se proponen ofrecer el soporte más adecuado a los cuidadores familiares, para que puedan seguir desempeñando las actividades derivadas del cuidado y a su vez minimicen el cansancio y la carga que supone cuidar. Desde hace una década se ha venido acrecentando el interés por planificar y desarrollar programas de soporte, desde la iniciativa pública y privada, dirigidos a cuidadores familiares. Los contenidos de estos programas son de diversa índole, y ofrecen asesoramiento e información, apoyo emocional, ayuda económica o descargas temporales del cuidado de las personas dependientes. La literatura científica revisada coincide en la importancia y la necesidad de coordinación y complementariedad que debe darse entre las redes informales y formales en el soporte a los cuidadores de las personas dependientes.

A tungsten coil atomizer was used to investigate the effect of heating programs with constant or variable drying temperatures on the atomization of Al, Cd, Cr and Pb. The variation of the surface temperature in the tungsten coil furnace can occur during each heating step due to the design of the power supply, that may apply constant voltages during a programmed time. For volatile elements (Cd), losses in sensitivity were observed when the program with a variable temperature was used. On the other hand, these effects are negligible for less volatile elements (Al and Cr) and any tested program, in different acidic media, could be used without appreciable changes in sensitivities. The results allow the establishment of proper heating programs for elements with different thermochemical behavior in the tungsten coil atomizer.

In this paper we review the basic techniques of performance analysis within the UNIX environment that are relevant in computational chemistry, with particular emphasis on the execution profile using the gprof tool. Two case studies (in ab initio and molecular dynamics calculations) are presented in order to illustrate how execution profiling can be used to effectively identify bottlenecks and to guide source code optimization. Using these profiling and optimization techniques it was possible to obtain significant speedups (of up to 30%) in both cases.

Values of repeatability (r) and reproducibility (R) are parameters of an analytical method. They are related to the maximum difference between two results of analysis (permissible range) and can be obtained by interlaboratorial comparisons. They represent great importance for the quality control of the results and decisions about the fitness-for-purpose of the method. Water determination in fuel oil samples were performed by 16 laboratories, using the Karl Fischer reaction, during the period from June 1997 to December 1999. Values of r and R were presented. Discussion is made in terms of the main factors that would be contribution to analytical method variabilities and uncertainties of final results.

[spa] El pasado 18 de mayo de 2007, tuvo lugar en Londres el último de los encuentros bienales del Proceso de Bolonia, en el que se reunieron los ministros responsables de la educación superior de los países participantes. En el consiguiente London Communiqué se resumieron las valoraciones de los ministros sobre el estado en el que dicho proceso se halla. Así, se pasó revista a los avances consolidados, a aquellas deficiencias que aún no han recibido la atención necesaria, y a las medidas y estrategias urgentes para su definitiva conclusión. El presente texto da noticia de todas estas cuestiones y, con motivo de ofrecer al lector referencias adicionales sobre el contexto general, incluye una breve síntesis de otros documentos directamente relacionados con los temas más destacados en Londres 2007: los programas de doctorado y la figura del doctorando.

The graduate programs in Chemistry were evaluated and classified from the data collected for the period 1998-2000 by CAPES, the Minister of Education agency that is responsible for the regulation and support of this level of human resources formation. The next classification will be made in 2004, from the data of the period 2001-2003. The years in between, like the present year, are used for an evaluation without classification, from what comments are emitted to the programs to know how their data are improving or not, before the new ranking reporting. The progresses in the area of chemistry in Brazil are analysed from the confrontation of the present data with that of all previous evaluations, since 1983. The results confirm that the research and graduate formation in the area of Chemistry is continuously improving in Brazil, particularly during the last seven years.

Interlaboratorial programs are conducted for a number of purposes: to identify problems related to the calibration of instruments, to assess the degree of equivalence of analytical results among several laboratories, to attribute quantity values and its uncertainties in the development of a certified reference material and to verify the performance of laboratories as in proficiency testing, a key quality assurance technique, which is sometimes used in conjunction with accreditation. Several statistics tools are employed to assess the analytical results of laboratories participating in an intercomparison program. Among them are the z-score technique, the elypse of confidence and the Grubbs and Cochran test. This work presents the experience in coordinating an intercomparison exercise in order to determine Ca, Al, Fe, Ti and Mn, as impurities in samples of silicon metal of chemical grade prepared as a candidate for reference material.

A research about the quality of life of the older persons of a municipality starting from the analysis of the perceptions, evaluations and expectations related to concrete spheres of their lives (familiar characteristics, housing, health, nearby environment, activities, needs and dependencies and persons helping them to satisfy needs) is presented. Answers to 1988 questionnaires obtained from two representative samples of older per - sons living in private homes in the city have been analysed: persons over 65 years old and a specific one composed by a sub-sample of the general one, with persons over 75 years living alone. Data shaping contextual indicators related to housing have been analysed. The auto - nomy to drive and the evaluation of on’s health seem to be positive indicators to take in account while sutying quality of life at these ages. Sentinel indicators of the physical and relational conditions in the family and indicators of dependency are analysed as well. The evaluations of the older persons about their own life conditions are also analysed through psychosocial indicators connected to housing, nearby environmenent, their activities andincomes. The results obtained are applicable in order to improve the decision making process in social intervention programmes developed in the field of ageing aiming to take into account their perspectives

The literature on the challenges of teacher education in undergraduate chemistry teaching is limited. In the present study, the application of didactic proposals elaborated by two authors of this paper, graduate students and teaching assistants of the teaching improvement program at University of São Paulo, was investigated in terms of their contribution to the teaching assistants' education and undergraduate students' receptivity toward them. Such proposals were based on the jigsaw cooperative learning strategy and applied in two undergraduate courses. The results indicate students' good receptivity and suggest their importance to teaching assistants' education.
