    «La primera cosa que Déu nostre Senyor nos amostrà ésser necessària a la vida humana, és I'agricultura» deia fra Miquel Agustí en el pròleg del seu 'Llibre dels secrets dágricultura, casa rústica ipastoril'. I Alonso de Herrera, en el proleg de la seva 'Agricultura general, escrivia': «El campo en conclusión nos da todas las cosas necessarias, y no podemos vivir sin él». La preocupació existent a l'edat moderna per l'agricultura, activitat que assegurava el sosteniment de la població i que constituïa la base de l'economia de l'època, es va manifestar en una sèrie de tractats d'agricultura i altres obres similars, d'autors molt diferents, d'estils i destinataris distints, apareguts en diversos paisos europeus, seguint la tradició clàssica dels 'scriptores de re rustica' també existent durant el període medieval i tenint en compte la tradició dels tractats islàmics..

    Three Selected Papers on Catalan Folklore

    This volume contains a selection of three translations of articles by Josep M. Pujol (Barcelona, 1947–2012), one in each of the three areas that he defined to characterise his work in the field of folklore: the theory of interactive artistic communication; the history of folklore studies and folk literature; and folk narrative. The three articles give a taste of the important contributions he made to the study of folklore, and which have been studied and contextualised by Carme Oriol in the introduction that precedes the three texts. This edition also includes the complete folkloric bibliography of Josep M. Pujol in chronological order, with all the references

    : Globally, the population of the elderly continue to rise. The increase of the number of elderly people is accompanied with a rise in health problems that are associated with the elderly. The degenerative process on the elderly causes the degeneration of the physical, psychological, and social conditions. One of the impacts of social change that is experienced by the elderly is the self-withdrawal of the elderly from their living environment. The purpose of the research is to analyze the association between social interaction and the quality of life of the elderly at BPLU Senja Cerah in North Sulawesi Province. The method of research is analytical descriptive with a cross-sectional design. The sample-taking technique in the research is purposive sampling with 32 samples. The collecting of data is done using a questionnaire. The processing of data uses the software computer with chi-square with the level of confidence interval of 95% (α=0,05). The results of the research shows the number of respondents with a good level of social interaction is 21 respondents, with 4 (12,5%) respondents having a sufficient quality of life, and 16 (50,0%) respondents with a high quality of life, while there are 12 respondents with a sufficient level of social interaction, where 9 (28,1%) respondents show a sufficient quality of life and 3 (9,4%) of respondents with a high quality of life and there is a p value of 0,004 < 0,05. This conclusion shows that there is a relationship between social interaction and the quality of life in the elderly

    En este artículo se estudia el fenómeno de la atenuación en las muestras de actuación de doce informantes del nivel educativo superior de Las Palmas de Gran Canaria, organizados en dos submuestras con una distribución paralela de las variables sociales y grabadas en diferentes años (alrededor de 1990, la primera, y de 2008, la segunda). La submuestra más antigua corresponde a los materiales del proyecto de norma culta de la capital grancanaria, mientras que la más reciente se inserta dentro de las obtenidas en la misma ciudad para el PRESEEA. La investigación sobre muestras de dos épocas distintas se inserta en la línea de trabajo formulada por los grupos españoles del PRESEEA como objetivo esencial para el próximo cuatrienio. El análisis cuantitativo de los factores extralingüísticos considerados permite constatar una evolución hacia un mayor uso de la atenuación, especialmente por parte de los hombres.This article examines the phenomenon of attenuation in speech samples corresponding to twelve speakers with a university educational level in Las Palmas de Gran Canaria, organized in two sub-samples with a parallel distribution regarding the social variables and recorded in different periods (the first one around 1990, and the second one in 2008). The earliest sub-sample corresponds to the corpus from the ‘norma culta’ project carried out in Las Palmas de Gran Canaria, whereas the most recent one forms part of the recordings obtained within the PRESEEA project in the same city. Research using samples from two different time periods is one of the essential objectives within the line of work of the Spanish groups belonging to PRESEEA for the next four years. The quantitative analysis of the extralinguistic factors taken into account in our research allows us to propose an evolution towards a greater use of attenuation, especially by men

    Interference of biodegradable plastics in the polypropylene recycling process

    [EN] Recycling polymers is common due to the need to reduce the environmental impact of these materials. Polypropylene (PP) is one of the polymers called commodities polymers' and it is commonly used in a wide variety of short-term applications such as food packaging and agricultural products. That is why a large amount of PP residues that can be recycled are generated every year. However, the current increasing introduction of biodegradable polymers in the food packaging industry can negatively affect the properties of recycled PP if those kinds of plastics are disposed with traditional plastics. For this reason, the influence that generates small amounts of biodegradable polymers such as polylactic acid (PLA), polyhydroxybutyrate (PHB) and thermoplastic starch (TPS) in the recycled PP were analyzed in this work. Thus, recycled PP was blended with biodegradables polymers by melt extrusion followed by injection moulding process to simulate the industrial conditions. Then, the obtained materials were evaluated by studding the changes on the thermal and mechanical performance. The results revealed that the vicat softening temperature is negatively affected by the presence of biodegradable polymers in recycled PP. Meanwhile, the melt flow index was negatively affected for PLA and PHB added blends. The mechanical properties were affected when more than 5 wt.% of biodegradable polymers were present. Moreover, structural changes were detected when biodegradable polymers were added to the recycled PP by means of FTIR, because of the characteristic bands of the carbonyl group (between the band 1700-1800 cm(-1)) appeared due to the presence of PLA, PHB or TPS. Thus, low amounts (lower than 5 wt.%) of biodegradable polymers can be introduced in the recycled PP process without affecting the overall performance of the final material intended for several applications, such as food packaging, agricultural films for farming and crop protection.This research was funded by Conselleria d'Educacio, Investigacio, Cultura y Esport de la Generalitat Valenciana, grant number APOSTD/2018/209.Samper, M.; Bertomeu, D.; Arrieta, MP.; Ferri, JM.; López-Martínez, J.
