Se pretende hacer un estudio general de la materia que de unidad y coherencia a posteriores estudios individualizados. Se considera que las ondas ocupan un lugar central en nuestra civilización y deben formar parte de la cultura media de una persona de nuestra época; saber distinguirlas de otros tipos de movimiento, conocer las ondas más importantes y sus aplicaciones. La primera parte contiene aspectos didácticos de la unidad: objetivos, contenidos, metodología, evaluación, etc. En la segunda parte se ofrece una serie de actividades variadas para el aula y actividades de evaluación y recuperación.

Este trabajo nace con el doble objetivo de dar a conocer París y de incitar a la lectura a los alumnos de Secundaria del Liceo Español. El proyecto consiste en mostrar la ciudad en diversos momentos de su historia a través de textos literarios y de la realización de recorridos construidos a partir de dichos textos. Además, puede servir como muestra de colaboración interdisciplinar, instrumento para la preparación de experiencias semejantes en otras ciudades y preparación de posibles viajes de estudios a la ciudad de París.

Aborda el tema de la enseñanza y aprendizaje en grupo, de la estructura de los grupos, roles, liderazgo y métodos de trabajo. Expone las técnicas que existen para el aprendizaje en equipo dentro del aula (asambleas, diálogos simultáneos, mesa redonda, debate público, torbellino de ideas, entrevista, dramatización o debate dirigido), así como la conducción y dinámica de grupos y el papel del profesor como guía del grupo.

Se exponen los resultados de la celebración del tercer coloquio sobre Geografía, que tuvo lugar los 25, 26 y 27 de octubre de 1985, en Salamanca. Estuvo organizado por la Asociación Española para el Progreso de las Ciencias. Se recogen resúmenes de las ponencias de dicho coloquio. Destacan la de Antonio López Gómez, Catedrático de Geografía de la Universidad de Valencia, titulada La Geografía Agraria en la Enseñanza Media: el ejemplo de las huertas levantinas, la de Pedro Plana, Profesor de Geografía, que versa sobre el método comparativo en la enseñanza de la geografía a los alumnos del bachillerato y la presentada conjuntamente por José Manuel Casas Torrea y Salvador Mensua Fernández, bajo el título Un método de investigación en el estudio de la utilización del suelo. Por último se señala que fuera de programa, el bibliotecario de la Institución para Formación del Profesorado de Enseñanza Laboral, José Sanz García, presentó a los congresistas una valorada relación de trabajos monográficos sobre Geografía Comarcal, existente en la citada Institución, cuya relación se incluye.

The objective of this work was to determine the viability equation constants for cottonseed and to detect the occurrence and depletion of hardseededness. Three seedlots of Brazilian cultivars IAC-19 and IAC-20 were tested, using 12 moisture content levels, ranging from 2.2 to 21.7% and three storage temperatures, 40, 50 and 65 degrees C. Seed moisture content level was reached from the initial value (around 8.8%) either by rehydration, in a closed container, or by drying in desiccators containing silica gel, both at 20 degrees C. Twelve seed subsamples for each moisture content/temperature treatment were sealed in laminated aluminium-foil packets and stored in incubators at those temperatures, until complete survival curves were obtained. Seed equilibrium relative humidity was recorded. Hardseededness was detected at moisture content levels below 6% and its releasing was achieved either naturally, during storage period, or artificially through seed coat removal. The viability equation quantified the response of seed longevity to storage environment well with K-E = 9.240, C-W = 5.190, C-H = 0.03965 and C-Q = 0.000426. The lower limit estimated for application of this equation at 65 degrees C was 3.6% moisture content.

The differential transmission of alleles from parents to affected children indicates that the locus under investigation is either directly involved in the occurrence of the disease or that there are allelic associations with other loci that are directly involved. Conditional logistic regression applied to a diallelic locus leads to a test with two degrees of freedom. The power of a single degree of freedom test to detect non-multiplicative allelic effects is discussed here.

Quality control on fruits requires reliable methods, able to assess with reasonable accuracy and possibly in a non-destructive way their physical and chemical characteristics. More specifically, a decreased firmness indicates the presence of damage or defects in the fruit or else that the fruit has exceeded its “best before date”, becoming unsuitable for consumption. In high-value exotic fruits, such as mangoes, where firmness cannot be easily measured from a simple observation of texture, colour changes and unevenness of fruits surface, the use of non-destructive techniques is highly recommendable. In particular, the application of Laser vibrometry, based on the Doppler effect, a non-contact technique sensitive to differences in displacements inferior to the nanometre, appears ideal for a possible on-line control on food. Previous results indicated that a phase shift can be in a repeatable way associated with the presence of damage on the fruit, whilst a decreased firmness results in significant differences in the displacement of the fruits under the same excitation signal. In this work, frequency ranges for quality control via the application of a sound chirp are suggested, based on the measurement of the signal coherence. The variations of the average vibration spectrum of a grid of points, or of point-by-point signal velocity allows the go-no go recognition of “firm” and “over-ripe” fruits, with notable success in the particular case of mangoes. The future exploitation of this work will include the application of this method to allow on-line control during conveyor belt distribution of fruits.

Emotion processing deficits can cause catastrophic damage to a person's ability to interact socially. While it is known that older adults have difficulty identifying facial emotions, it is still not clear whether this difficulty extends to identification of the emotion conveyed by prosody. This study investigated whether the ability of older adults to decode emotional prosody falls below that of young adults after controlling for loss of hearing sensitivity and key features of cognitive ageing. Apart from frontal lobe load, only verbal IQ was associated with the age-related reduction in performance displayed by older participants, but a notable deficit existed after controlling for its effects. It is concluded that older adults may indeed have difficulty deducing the emotion conveyed by prosody, and that while this difficulty can be exaggerated by some aspects of cognitive ageing, it is primary in origin.
