This short essay deals with literary representations of identity and of social reality, especially in relation to the novelistic works published by the Spanish writer Juan José Millás. The article is divided into three parts. The first section is dedicated to a general overview of the new perspectives brought by the contemporary ‘linguistic turn’ in culture, which is currently considered as the product of different discourses and not as an ontological datum. The postmodern condition, on the other hand, is described as the age in which it has become radically difficult to rely on such ideas as “nation” and “people” for the construction of personal identity. The second part of the article identifies Millás’ poetics as an excellent example of describing the neurotic symptoms produced by the urban way of life in Western communities. Millás recognizes the separateness between language and material reality as the origin of the subject's isolation, especially in contemporary life. Finally, the third part handles with Lo que sé de los hombrecillos, the last novel by Millás, in which we witness a significant switch from neurosis to psychosis in the mind of the protagonist who offers us a distorted realisation of his idea of community and plenitude.

Fumigation with phosphine gas is the primary method of controlling stored grain pests. In Turkey, phosphine has been used extensively since the 1950's. Even though high levels of phosphine resistance have been detected in several key stored products pests across the world, it has never been studied in Turkey despite this long history of phosphine use. High-level phosphine resistance has been detected and genetically characterised previously in the rust red flour beetle, Tribolium castaneum in other countries. Since this pest is also a common problem in stored grain environment in Turkey, the current study was undertaken for the first time, to investigate the distribution and strength of phosphine resistance in T. castaneum. Four strains of T. castaneum were tested through bioassays for determining the weak and strong phosphine resistance phenotypes on the basis of the response of adults to discriminating phosphine concentrations of 0.03 mg/L and 0.25 mg/L, for 20 hour exposures respectively. Phenotype testing showed all strains exhibited some level of phosphine resistance with a maximum level of 196 fold. Sequencing and genetic testing of seven field-collected strains showed that all of them carried a strong resistance allele in at the rph2 locus similar to the one previously reported. Our results show that strong resistance to phosphine is common in Turkish strains of T. castaneum.

The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the part loses mass during the machining and the complex shape of the tools that are used. The present work proposes a methodology for chatter avoidance in the milling of flexible thin floors with a bull-nose end mill. First, a stability model for the milling of compliant systems in the tool axis direction with bull-nose end mills is presented. The contribution is the averaging method used to be able to use a linear model to predict the stability of the operation. Then, the procedure for the calculation of stability diagrams for the milling of thin floors is presented. The method is based on the estimation of the modal parameters of the part and the corresponding stability lobes during the machining. As in thin floor milling the depth of cut is already defined by the floor thickness previous to milling, the use of stability diagrams that relate the tool position along the tool-path with the spindle speed is proposed. Hence, the sequence of spindle speeds that the tool must have during the milling can be selected. Finally, this methodology has been validated by means of experimental tests.

The physical, chemical and pasting properties of the flour and isolated starches from six different bean cultivars (Phaseolus vulgaris L.) were investigated in order to obtain information for application in new products. The protein and total starch contents of the bean flours ranged from 17.72 to 20.27% and from 39.68 to 43.78%, respectively. The bean starches had low amounts of proteins, lipids and ash and showed an amylose content ranging between 45.32 and 51.11% and absolute density values between 1.55 and 1.78 g.cm?3. The bean starch granules were round to oval with a smooth surface. Results viscoamylographic profiles of the starches and flours showed the possibility of selecting cultivars for specific applications according to these characteristics.

%'e compute the divergent part of the three-point vertex function of the non-Abelian Yang-Mills gauge field theory within the stochastic quantization approach to the one-loop order. This calculation allows us to find four renormalization constants which, together with the four previously obtained, verify, to the calculated order, some Ward identities.

TESLA project (Transfering Energy Save Laid on Agroindustry) financed by the European Commission, had the main goals of evaluating the energy consumption and to identify the best available practices to improve energy efficiency in key agro-food sectors, such as the olive oil mills. A general analysis of energy consumptions allowed identifying the partition between electrical and thermal energy (approximately 50%) and the production processes responsible for the higher energy consumptions, as being the in the mill and paste preparation and the phases separation. Some measures for reducing energy waste and for improving energy efficiency were identified and the impact was evaluated by using the TESLA tool developed by Circe and available at the TESLA website.

ResumenEste diario fue amablemente enviado a la Revista de Historia por la antropóloga Dra. María Eugenia Bozzoli, miembro de la Academia de Geografía e Historia de Costa Rica, en el mes de diciembre de 2005. Como explicó Bozzoli en esa ocasión, el documento había sido entregado años atrás a esa Academia por el señor Tomás M. Zeledón, quien adjuntó una carta de presentación explicando cómo había llegado el diario a sus manos y quién era R. J. Phillips. Ambos documentos quedaron archivados en la academia hasta que años más tarde, a instancias de Bozzoli, el documento fue digitado y enviado a la Revista de Historia. Aunque desconocemos qué ha sucedido con el señor R. J. Phillips, consideramos que la publicación tanto de su diario como de la carta de Tomás M. Zeledón es oportuna e importante.

Talk is the foundation for thought and understanding, and the key to literacy learning. Research demonstrates that powerful meta-cognitive strategies can be taught to help students self-monitor their comprehension when reading print and digital texts. This paper provides a repertoire of motivating speaking and listening tips to develop the meta-cognitive thinking of students in the elementary years.
