AN INVESTIGATION OF VOLATILE ORGANIC AIR CONTAMINANTS IN THE INDOOR MANUFACTURED HOUSING ENVIRONMENT (TEXAS)

Manufactured housing has been found to have substantial levels of formaldehyde in the indoor air. Because mobile homes are more affordable than conventional housing, there has been a large increase in their use in the U.S. This increase in mobile home use has been substantial in the sunbelt regions such as Texas, where high temperatures and humidities may enhance out-gassing of formaldehyde and other volatile organic compounds from construction and furnishing materials and increase any potential health hazards.^ The influences of environmental, architectural and temporal factors on the presence of indoor formaldehyde and other organic compounds were investigated in conjunction with the Texas Indoor Air Quality Study of manufactured housing. A matched pair of mobile homes, one with electric heating and cooking utilities and the other with propane gas utilities, were used for a series of controlled experiments over a fourteen month period from October, 1982 through November, 1983.^ Over this fourteen month period formaldehyde levels decreased approximately 33%. Daily fluctuations of 20% to 40% were observed even with a constant indoor temperature. An increase in indoor temperature of 8(DEGREES)C doubled the measured formaldehyde concentration. Opening windows resulted in decreases of indoor formaldehyde levels of up to 50%. Studies of the impact of propane as a cooking source showed no increase in formaldehyde levels with stove use.^ The presence and concentration of selected volatile organic compounds is influenced greatest by occupancy. Occupants continually open and close windows and doors, vary the operation and settings (temperature) of air control systems, and vary in their selection of furnishings and use of consumer products, which may act as sources of indoor air contaminants. ^

Proceedings of the Twenty-Fifth Annual Biochemical Engineering Symposium

The Annual Biochemical Engineering Symposium Series started in 1970 when Professors Larry E. Erickson (Kansas State University) and Peter J. Reilly (then with University of Nebraska-Lincoln) got together in Manhattan, KS along with their students for a half-day powwow and technical presentation by their students. Ever since then, it has been a forum for Biochemical Engineering students in the heartland of USA to present their research to their colleagues in the form of talks and posters. The institutions actively involved with this annual symposium include Colorado State University, Kansas State University, Iowa State University, University of Colorado, University of Kansas, University of Missouri-Columbia, and University of Oklahoma. The University of lowa and University of Nebraska-Lincoln have also participated in the conference in recent years. The host institutions for the different symposia have been: Kansas State University (1, 3, 5, 9, 12, 16, 20), Iowa State University (6, 7, 10, 13, 17, 22), University of Missouri-Columbia (8, 14, 19, 25), Colorado State University (II, 15, 21), University of Colorado (18, 24), University of Nebraska-Lincoln (2, 4), University of Oklahoma (23). The next symposium will be held at Kansas State University. Proceedings of the Symposium are edited by faculty of the host institution and include manuscripts written and submitted by the presenters (students). These often include works-in-progress and final publication usually takes place in refereed journals. ContentsPatrick C. Gilcrease and Vincent G. Murphy, Colorado State University.

Las muchachas ahorrativas : El rol de las mujeres peronistas en el Plan Económico de Austeridad y el 2° Plan Quinquenal

En este trabajo propongo analizar el rol asignado a las mujeres peronistas y a las unidades básicas femeninas del Partido Peronista Femenino como promotoras del ahorro y la economía doméstica dentro del Plan Económico de Austeridad y el 2° Plan Quinquenal. Luego de la amplia confirmación de la popularidad del gobierno obtenida en las elecciones de noviembre de 1951, el presidente Perón consideró oportuno producir una rectificación y un ajuste en el rumbo de la política económica. Se trataba de una serie de medidas imprescindibles para superar una coyuntura que se tornaba crítica, y que se resumían en el aumento de la producción y la austeridad en el consumo. Esta última responsabilidad recayó en la mujeres - amas de casa amparadas en la acción de las unidades básicas femeninas que actuaron como consejeras y promotoras de los planes de austeridad implementando una serie de medidas que iban desde la cursos de cocina que enseñaban a cocinar con productos alternativos y más económicos hasta la fiscalización de los comercios que no cumplían con los precios máximos oficiales.

Case Study of Applied LIP Approach/Activities in the Philippines The Training Services Enhancement Project for Rural Life Improvement (TSEP-RLI) Experience

TSEP-RLI was a technical cooperation project jointly conducted by GOP thru DA-Agricultural Training Institute (ATI) and GOJ thru JICA aimed at institutionalizing the training program for Rural Life Improvement (RLI) at the (ATI). As expected, farmers, fisherfolk, women, youth and extension agents were provided with efficient and effective training services from ATI leading to the improvement of quality of life in the rural areas through efforts of human resource development. The ATI- Bohol was chosen as the model center where participatory trials and various activities of the project were undertaken for five years. These activities were participatory surveys and data collection of on-farm and off-farm productive activities; planning workshop for RLI; feedbacking of survey results and action plans to the community and the Local Government Units (LGUs), and signing of Memorandum of Agreement between the Project and participating LGUs. The above activities were done to facilitate the planning and development of most effective and necessary rural life improvement activities, to confirm the willingness of the people to support and participate and to formalize the partnership between the Project and the LGUs. Since the concept of rural life covers a vast range of activities, a consensus had been reached that the total aspects of rural life be grasped in three spheres, namely, Production & Livelihood (P/L), Rural Living Condition (RLC) and Community Environment (C/E). The RLI for Ubi (Yam) Growers was one of the pilot activities undertaken in two pilot barangays and the target beneficiaries were members of the Rural Improvement Club (RIC- a group of organized women) with the LGU of the Municipality of Corella as the implementing partner. During the planning workshop, the barangay residents articulated their desire to promote production and processing of ubi (sphere on P/L - as the entry point), lack of nutritious food was one of the identified problem (sphere on RLC- expansion point) and environmental degradation such as deforestation, and soil erosion was another problem articulated by the community people (sphere on C/E- expansion point). Major activities that were undertaken namely, Ubi cooking contest, cooking/processing seminar, training courses on entrepreneurial development, ubi production and storage technology, packaging and product design, human resource development and simplified bookkeeping motivated the beneficiaries as well as developed and enhanced their skills & capabilities while strengthening their associations. Their participation to the 5 ubi festivals and other related activities had brought some impacts on their economic and rural life improvement activities. The seven principles of TSEP-RLI include the participatory process, holistic approach, dialogical approach, bottom -up training needs assessment, demand-driven approach, cost sharing approach and collaborative implementation with other agencies including LGUs and the community.

Productive performance, carcass and meat quality of intact and castrated gilts slaughtered at 106 or 122 kg BW

A total of 200 (Landrace3Large White dam3Pietrain3Large White sire) gilts of 5063 days of age (23.361.47 kg BW) were used to investigate the effects of castration (intact gilt, IG v. castrated gilt, CG) and slaughter weight (SW; 106 v. 122 kg BW) on productive performance, carcass and meat quality. Four treatments were arranged factorially and five replicates of 10 pigs each per treatment. Half of the gilts were ovariectomized at 58 days of age (8 days after the beginning of the trial at 29.861.64 kg BW), whereas the other half remained intact. The pigs were slaughtered at 106 or 122 kg BW. Meat samples were taken at Musculus longissimus thoracis at the level of the last rib and subcutaneous fat samples were taken at the tail insertion. For the entire experimental period, CG had higher ( P,0.05) BW gain and higher ( P,0.001) backfat and Musculus gluteus medius fat thickness than IG. However, IG had higher ( P,0.05) loin and trimmed primal cut yields than CG. Meat quality was similar for IG and CG but the proportion of linoleic acid in subcutaneous fat was higher ( P,0.001) for IG. Pigs slaughtered at 122 kg BW had higher ( P,0.001) feed intake and poorer feed efficiency than pigs slaughtered at 106 kg BW. An increase in SW improved ( P,0.001) carcass yield but decreased ( P,0.05) trimmed primal cut yield. Meat from pigs slaughtered at the heavier BW was redder (a*; P,0.001) and had more ( P,0.01) intramuscular fat and less thawing ( P,0.05) and cooking ( P,0.10) loss than meat from pigs slaughtered at the lighter BW. In addition, pigs slaughtered at 122 kg BW had less ( P,0.01) linoleic acid content in subcutaneous fat than pigs slaughtered at 106 kg BW. Castration of gilts and slaughtering at heavier BW are useful practices for the production of heavy pigs destined to the dry-cured industry in which a certain amount of fat in the carcass is required. In contrast, when the carcasses are destined to fresh meat production, IG slaughtered at 106 kg BW is a more efficient alternative.

Influence of castration on growth performance and carcass and meat quality of heavy female pigs

The main objetive of this Doctoral Thesis was to study the influence of female castration and pig sex on growth performance and carcass and meat quality of white pigs slaughtered at different final weights. Three experiments (Exp.) were conducted. In Exp. 1, a total of 200 (Landrace * Large White dam x Pietrain * Large White sire) gilts of 50 ± 3 days of age (23.3 ± 1.47 kg BW) was used to investigate the effects of castration (intact females, IF vs. castrated feamles, CF) and slaughter weight (106 vs. 122 kg BW) on productive performance and carcass and meat quality. There were four experimental treatments arranged as a 2 x 2 factorial and 5 replicates of 10 pigs each per treatment. Half of the gilts were ovariectomized at 58 d of age (8 days after the beginning of the trial; 29.8 ± 1.64 kg BW) whereas the other half remained intact. Meat samples were taken at m. Longissimus thoracis at the level of the last rib and subcutaneous fat samples were taken at the tail insertion. For the entire experiment period, CF had higher BW gain (P<0.05) and backfat and m. Gluteus medius (GM) fat thickness (P<0.001) than IF. However, IF had higher loin and trimmed primal cut yields (P<0.05) than CF. Meat quality was similar for IF and CF but the proportion of linoleic acid in subcutaneous fat was higher (P<0.001) for IF. Pigs slaughtered at 122 kg BW had higher (P<0.001) feed intake and poorer feed efficiency than pigs slaughtered at 106 kg BW. An increase in slaughter weight (SW) improved (P<0.001) carcass yield but decreased (P<0.05) trimmed primal cut yield. Meat from females slaughtered at the heavier BW was redder (a*; P<0.001) and had more (P<0.01) intramuscular fat and less thawing (P<0.05) and cooking (P<0.10) loss than meat from females slaughtered at the lighter BW. Also, females slaughtered at 122 kg BW had less (P<0.01) linoleic acid content in the subcutaneous fat than pigs slaughtered at 106 kg BW. Castration of gilts and slaughtering at heavier BW might be useful practices for the production of heavy pigs destined to the dry cured industry in which a certain amount of fat in the carcass is required. In contrast, when the carcasses are destined to fresh meat production, IF slaughtered at 106 kg BW are a more efficient alternative. In Exp. 2, crossbred pigs (n=240) from Pietrain*Large White sires mated to Landrace*Large White dams with an average of 100 d of age (60.5 ± 2.3 kg) were used to investigate the effects of gender and slaughter weight (SW) on growth performance and carcass and meat quality characteristics. There were 6 treatments arranged factorially with 3 genders (IF vs. CF vs.castrated males, CM) and 2 SW (114 vs. 122 kg BW). Each of the 6 combinations of treatments was replicated 4 times and the experimental unit was a pen with 10 pigs. Castrated males and CF ate more feed, grew faster and had more carcass backfat depth and fat thickness at the GM muscle, but lower loin yield than IF (P<0.05). In addition, CF and CM had more intramuscular fat (P<0.05) and less linoleic acid content in the subcutaneous fat (P<0.01) than IF. Pigs slaughtered at 122 kg BW had lower ADG (P<0.05), poor gain-to-feed ratio (P<0.05), and more GM fat than pigs slaughtered at 114 kg BW (P < 0.05). It is concluded that CF and CM had similar productive performance and meat quality characteristics when slaughtered at the same age, and that the castration of females improved daily gains and increased weight and fat content of primal cuts with respect to IF. Therefore, castration of females is recommended in pigs destined to the dry-cured industry because of the beneficial effects on the quality of the primal cuts. In Exp. 3, the effects of gender and castration of females (IF vs. CF vs. CM) on performance and carcass and meat quality were studied in crossbred pigs (Landrace x Large White dams x Duroc sires) slaughtered at 119.2 (trial 1) or 131.6 (trial 2) kg BW. Intact females had better feed conversion and less carcass fat than CF and CM. Trimmed shoulder yield was higher for CM than for CF with IF being intermediate. Primal cut yield and meat quality, however were similar for all treatments. Proportion of linoleic acid in backfat was lower for CF than for IF or CM, and the differences were significant in pigs slaughtered witn 131.6 kg BW. The higher fat content and the fatty acid profile favour the use of CF and CM over IF for the production of heavy pigs destined to the dry-cured industry.

Sola romani: morteros hidráulicos romanos en la Península Ibérica

En esta investigación se han analizado morteros de cal de cronología romana en el interior de la Península Ibérica. Para ello, se seleccionó una serie de muestras procedentes de diversos yacimientos, y de estructuras de carácter industrial. Estas muestras presentan aditivos cerámicos y conglomerantes de cal, como característica principal. Desde un principio el esfuerzo debía de centrarse en los fragmentos cerámicos presentes en los morteros. Para ello se documentaron varios morteros con aditivos cerámicos, a fin de conocer sus características básicas (componentes, distribución, micro-estratigrafía, granulometría, etc.). Por ello, y una vez tomadas las muestras, ésta fueron tratadas y procesadas para desarrollar una primera fase de estudio por medio de macroscopía. Se obtuvieron buenos resultados en cuanto a la caracterización visual de los morteros, localizando y documentando los fragmentos cerámicos. Durante la observación de dichos aditivos se observó que los fragmentos cerámicos tenían unas coronas o anillos de coloración que recorrían el borde, justo al contacto con la matriz de cal. Fueron seleccionados algunos fragmentos en los que eran más visibles dichos anillos. A fin de conocer la posible relación entre algunos yacimientos cercanos y la presencia de dicho anillo cromáticos se desarrolló una microscopía óptica polarizada, realizando láminas delgadas de las muestras y sobre los fragmentos cerámicos más determinantes, en concreto de una serie de enclaves del valle del Henares. Además de caracterizar microscópicamente los morteros, se observó que los anillos no eran un defecto visual ni una alteración física, producida tal vez por la extracción, la fase del corte o por la cocción de la cerámica. Tras analizar varios ejemplares se pudo apreciar que esos anillos eran habituales en todas las muestras y que se presentaban de diferente manera, es decir, que se observaban en granos cerámicos de diferentes características físicas (cochura, tamaño, situación con respecto del conglomerante, etc.). A fin de conocer los aspectos químicos de dicha alteración se seleccionó un grupo de muestras en las que los resultados macroscópicos habían sido muy claros, y en las que la microscopía óptica polarizada había determinado en los bordes, áreas adecuadas para otros análisis. Se realizó un mapeado o mapping de elementos químicos, a fin de saber qué podía estar sucediendo en esa interfaz entre el fragmento cerámico y la matriz de cal. Gracias a los resultados obtenidos se comprobó que existía una acumulación potencial de calcio tanto en el interior de los granos cerámicos como en el exterior, justo en la zona de contacto con el conglomerante, formando manchas que recorrían longitudinalmente el borde. Estos datos fueron muy útiles para llevar a cabo la siguiente fase de estudio, que permitiría conocer puntualmente qué estaba sucediendo químicamente en esa zona de contacto. Finalmente y con el objetivo de describir química y puntualmente este efecto en las adiciones cerámicas, se volvió a seleccionar una serie de muestras, escogidas esta vez en función de los granos cerámicos que cumpliesen unas variables estadísticas. Se eligieron granos con distintos tipos de cocciones, así como granos con tamaños diversos y granos con aditivo ceniciento en la matriz de cal, pensando que podrían ser las variables más útiles de interpretar de existir algún tipo de cambio químico entre la arcilla cocida y la matriz de cal. Tales variables se adaptaron a un sistema estadístico multi-varial y geométrico, con el objetivo de sintetizar los resultados y visualizar de forma óptima los datos en conjunto, como se ha comentado en varias ocasiones en este trabajo. Una vez seleccionados los granos por variables se procedió a realizar un análisis lineal y espectral semi-cuantitativo de SEM-EDX, con el que se caracterizaba químicamente una sección lineal del grano, desde la matriz de arcilla cocida de la cerámica hasta la matriz de cal –del interior al exterior del grano- pasando por el centro de la banda de reacción. Este análisis permitió determinar que se había producido una serie de cambios químicos porcentuales en los granos de cerámica. Dichos cambios se resumen en un incremento global de los porcentajes de calcio en el interior de las bandas de reacción de la cerámica, desde el borde mismo del anillo hasta el exterior. Así también se observaron picos porcentuales en el interfaz del fragmento cerámico con la matriz de cal, lo que confirmaba los resultados obtenidos por medio del mapping. Globalmente en todas las muestras se apreció un hombro en las gráficas de calcio a su paso por la zona de afección del anillo de reacción. Los restantes porcentajes de magnesio, silicio y aluminio se mantienen normales. En esta tesis se ha confirmado que dicho incremento global de calcio se acentúa en las muestras en donde no hay cenizas en la matriz de cal. Los casos correspondientes a estos granos sufren un incremento mayor que en el resto. La segunda variable que sufre un mayor incremento de calcio es la que corresponde a granos con buena cocción de la arcilla. Por lo tanto, parece que la tercera variable, la que corresponde con el tamaño del fragmento cerámico, no es decisiva. Por lo tanto, teniendo en cuenta la prueba visual de los anillos de reacción, y atendiendo a los resultados químicos, podríamos pensar que ese incremento de calcio en la banda de reacción de los fragmentos cerámicos se debió a una absorción de calcio en el interior de la arcilla cocida en la fase inmediatamente previa al fraguado, incluso durante el apagado de la cal. Es en este punto donde estaría la clave del cambio químico que se produce en esta interfaz, el calcio sílice-aluminato del que algunos autores ya han investigado. Esta absorción de calcio en el interior del grano no vendría sola, sino que generaría una costra de cal en el interfaz exterior de la cerámica, la cual ha sido observada químicamente por mapping y mineralógicamente por medio de microscopía óptica de polarización. La consecuencia de estos resultados es, primero, la mejora de nuestro conocimiento general acerca del factor hidráulico en los morteros. Asimismo se aprecia que la incorporación de materiales orgánicos como cenizas, puede alterar los porcentajes de calcio en el interior de los aditivos cerámicos, por lo que habría que sopesar, en trabajos futuros, si este tipo de material es adecuado o no en las mezclas destinadas a la restauración, así como seguir indagando en las propiedades de los morteros con la incorporación de aditivos orgánicos. Desde el punto de vista de la catalogación de los suelos industriales hidráulicos de época romana, además de mejorar la documentación incorporando micro-estratigrafías y granulometrías, la investigación de este material histórico constructivo mejora en cuanto a que se incorporan ensayos sencillos, que facilitan incluso la peritación de un estado de conservación por medio de una lupa binocular. Arqueológicamente hablando, es muy interesante correlacionar fábricas diferentes de estructuras situadas o bien en un mismo yacimiento, o bien en una misma área regional. Los estudios de caracterización y micro-estratigrafía no sólo aportan datos nuevos de cara a la restauración de morteros, sino que crean la posibilidad de generar patrones constructivos que sirvan de fósiles-guía para datar relativamente a unas estructuras o a otras. En lo referido a los resultados obtenidos en los diferentes complejos arqueológicos se ha observado una diferencia entre los morteros destinados a piletas y cubetas con respecto a los suelos industriales de uso indeterminado. La muestra correspondiente al yacimiento de Las Arenas no dispone de ninguna micro-estratigrafía, como sí por el contrario en las muestras obtenidas en Rotonda de Mejorada, Val de la Viña y La Magdalena. En estos enclaves las estructuras presentan grandes similitudes, con diferentes niveles constructivos empleando morteros de cal con áridos y gravas en las capas interiores, y áridos con adiciones cerámicas en las exteriores. En lo relativo a la granulometría las adiciones cerámicas de las muestras de Val de la Viña y La Magdalena presentan varias coincidencias en cuanto al tamaño de los granos y la distribución. Asimismo, de las muestras tomadas en La Magdalena, existe una gran diferencia entre las muestras MG1, MG2, MG3 y MG4 con respecto a las muestras MG5 y MG6, correspondientes éstas últimas a un mortero con fragmentos cerámicos de gran tamaño. Las estructuras EMG1 y EMG2, correspondientes a una cubeta y una pileta de La Magdalena, guardan similitud en lo referido a la micro-estratigrafía y a la granulometría. Se ha determinado que su función, así como su fabricación, debieron estar vinculadas a un mismo contexto cronocultural. Química y mineralógicamente, las muestras presentan características iguales, con presencia de un conglomerante de cal con áridos y aditivos cerámicos de diferentes cochuras. Destaca la muestra de Las Arenas, con un tamaño de los fragmentos cerámicos muy superior al resto, seguido de la estructura EMG3 de La Magdalena. Las muestras restantes de éste enclave, junto con las muestras recogidas en Val de la Viña y Rotonda de Mejorada presentan condiciones similares. En conclusión, los datos revelan que existían diferentes fábricas destinadas a distintas finalidades, y que las estructuras industriales empleaban aditivos cerámicos para la manipulación de productos con líquidos, de distintas densidades pero que requerían de cierto grado de hidraulicidad. ABSTRACT Lime Roman mortars from the Iberian Peninsula has been analyzed in this reesearch. A group of samples were selected from some sites and all the samples come from industrial structures. All this samples show ceramic additives. From the start, the effort was centered in the pieces of pottery that were found in the mortars. The samples were treated and processed to develop a first phase of the research using macroscopy. With this technique, great results were achieved in the characterization of mortars, the microstratigraphy and the location of the ceramic pieces. While observing these pieces, it was seen that the fragments of pottery had a ring bordering the piece. The pieces with the bigger and more vivid rings were chosen and they were analyzed by a polarized light microscope. The mortars were characterized microscopically and it also showed that the rings were not a physical alteration or a visual defect. After some more tests, the rings were a chemical change associated with the hydraulicity of the mortar. The best samples were selected and mappings of their chemical elements were performed in order to know what could be happening in the interface between the ceramic matrix fragment and lime. With the results obtained it was found that there was a potential; both calcium accumulation within the ceramic grains and outside, just in the area of contact with the binder, forming spots longitudinally along the edge. These data were very useful for carrying out the next phase of study, which would meet promptly what was happening chemically in the area of contact. Another group of samples were taken, and this time focused on ceramic grains that met a statistical variables. Grains were chosen with two types of cooking as well as grains with different sizes and grains with ash additive in the matrix of lime, thinking that might be the most logical to be some sort of chemical change between the baked clay and lime array variables . Such variables were adapted to a multi-varial and geometric statistical system in order to synthesize the results and optimally display the data together, as mentioned several times in this work. After selecting the variables grains proceeded to perform a linear and spectral analysis SEM-EDX. This analysis led to determine that the chemical changes were graduals. These changes are summarized in an increase in the percentages of calcium inside the reaction rim of ceramics, from the edge to the outer ring. So percentage increasing is also observed at the interface of the ceramic matrix fragment with lime, confirming the results obtained by the mapping. Overall in all samples can be seen a shoulder in graphic calcium through the area of the ring reaction condition. The remaining percentages of magnesium, silicon and aluminum are usual. We have promptly confirmed that the increase of calcium is accentuated in samples where there is no ash and lime matrix. Cases for these grains suffer a greater increase than the rest. The second variable suffering more calcium is increased corresponding to good cooking grains with clay. Therefore, it appears that the variable size of the fragment is not critical. Therefore, considering the visual tests to the rings and their response to chemical results, we might think that increasing calcium inside the ceramic fragments was due to an injection of calcium inside clay in the run-up to the setting phase. It is at this point that would be the key to the chemical change that occurs at this interface, silica-calcium aluminate some authors have already investigated. This injection of calcium into the grain does not come alone, but generate a lime crust on the outside interface of ceramics, which we tested for mapping is real in our samples. The consequence of these results is the improvement of our understanding of historical hydraulic factor in building materials, such as mortar. For example, knowing that the incorporation of organic materials such as ash powder, may be detrimental to the injection of calcium inside the ceramic additives. Archaeologically speaking, it's very interesting to correlate different factories or structures located on a single site, or in the same regional area. Characterization studies and microstratigraphy not only provide new information to help restore mortars, but create the possibility of generating constructive patterns that serve as guide fossils to determinate the age of the structures. With regard to the results obtained in different archaeological sites it has seen a difference between mortars of pools or sinks with respect to industrial floors of undetermined use. The sample of the site of Las Arenas does not have any micro-stratigraphy, as if instead in the samples obtained in Rotonda de Mejorada, Val de la Viña and La Magdalena sites. In these settlements the structures are really similar, with different construction levels using lime mortars with aggregates and gravel in the inner layers, and ceramic aggregates as external additions. With regard to the grain size of the ceramic additions Val de la Viña and La Magdalena samples has several coincidences about the size of grains and distribution. Also, samples taken at La Magdalena, there is a difference between the MG1, MG2, MG3 and MG4 samples and the MG5 and MG6 samples, so the last corresponding to a mortar samples with larger ceramic fragments. The EMG1 and EMG2 structures, corresponding to a bucket and a pool of La Magdalena settlement, have similarities with regard to micro-stratigraphy and grain size. It has been determined that the function and manufacturing must be linked with a same chronocultural context.

A taste of the technical cuisine: metals and other ingredients

According to cognitive linguistics, language has an experiential origin based on perception, sensory motor activities and our knowledge of the world. Our thought operates by establishing similarities, links and associations that enable us to talk about one thing in terms of another as shown in the example of love as a journey (Lakoff and Johnson, 1980). Metaphor and metonymy are conceptual and linguistic tools that make possible most of these cognitive operations. Since metaphor is an essential element of human communication, the discourse of specialised disciplines includes metaphorical mappings and numerous examples of metaphorical expressions, for example in economics, where business is mapped in terms of war (White, 2004; Herrera & White, 2000), electrotechnics with electrical components understood as couples (Roldán- Riejos in preparation) or in civil engineering where a bridge is conceptualized as a person (Roldán-Riejos, 2013). In this paper, the metaphors: WORKING WITH METALS IS COOKING/ TRABAJAR CON METALES ES COCINAR and METALS ARE CULINARY OBJECTS/ LOS METALES SON OBJETOS CULINARIOS are explored. The main aim is to show that the cooking metaphor is widely spread in the metallurgical domain in English and Spanish, although with different nuances in each language due to socio-cultural factors. The method adopted consists of analysing examples taken from the: Bilingual Dictionary of Scientific and Technical Metaphors and Metonymies Spanish- English/English-Spanish, a forthcoming and rigorously documented bilingual dictionary that sums up research on conceptual, linguistic and visual metaphor and metonymy in different areas of engineering (Roldán-Riejos and Molina, 2013). The present paper studies in detail English and Spanish cross-linguistic correspondences related to types of metals and processes. It is suggested that they reflect synesthetic metaphoric mappings. The exploitation of cognitive conceptual metaphor in the ESP classroom is lastly recommended.

DONA FLOR E SEUS DOIS MARIDOS: O LIVRO E A MINISSÉRIE

Este trabalho é centrado na análise de Dona Flor e seus dois maridos, minissérie produzida pela Rede Globo de Televisão em 1997, para o horário das 22 horas e veiculada na emissora, em 20 capítulos. Com direção geral de Mauro Mendonça Filho foi adaptada por Dias Gomes, com co-autoria de Marcílio Moraes e Ferreira Gullar a partir do romance homônimo do escritor baiano Jorge Amado, publicado pela primeira vez em maio de 1966 pela editora Livraria Martins, com tiragem de 75 mil exemplares. Nosso objetivo foi verificar qualitativamente o tratamento dado a um tema específico, presente no romance e na minissérie, qual seja, a culinária, na passagem do romance para o produto televisivo, sob o foco do erotismo. Como metodologia utilizamos o método qualitativo, e como técnica, a análise de conteúdo. Demonstrou-se que na passagem do romance para a televisão, a culinária foi retratada de forma menos erotizada, em relação ao livro, em função da exigência do suporte, bem como sua inserção tratou de evidenciar o caráter regional da minissérie.(AU)

LIBERTAÇÃO NAS TRILHAS DA JUSTIÇA: Estudo histórico e hermenêutico de Isaías 42,1-4

O presente trabalho tem como objetivo propor um estudo do cântico do escravo de Javé em Isaías 42,1- 4. Javé apresenta uma nova liderança, com um novo jeito de pensar e de agir para reconstruir um mundo novo baseado no direito e na solidariedade. É uma tarefa desafiadora para mim e ao mesmo tempo uma alegria em poder compartilhar com os meus amigos o conteúdo de um texto do Antigo Testamento. Afinal, o cântico do escravo de Javé é uma fonte inesgotável de sabedoria. Saciou o povo judaíta exilado a de dois mil e quinhentos anos atrás e continua jorrando água viva até em nossos dias matando a sede de todos aqueles e aquelas que lutam pela justiça. Os versos escolhidos são frutos de uma experiência de vida concreta dos exilados desacreditados por todos no cativeiro da Babilônia. No fundo é uma crítica aos falsos deuses criados pelos poderosos para justificar um sistema de opressão. A criatividade do profeta está em retomar os eventos históricos que marcaram a vida do povo exilado e atualizá-los dentro de um novo contexto histórico. Isto demonstra sua agilidade no conhecimento. Cada palavra é pensada dentro de um contexto maior envolvendo a vida e a história. O profeta é um sábio poeta, que fala de Deus como ninguém falou antes. Utiliza símbolos, imagens e metáforas que apontam para um mundo novo que ainda não existe, onde reinará o direito, a justiça e a paz. Essa mudança acontecerá a partir da missão que a liderança eleita desempenhará junto do povo oprimido e injustiçado. O líder será como o fermento na massa para a nova sociedade, baseada na igualdade e na partilha. O espírito de Javé estará agindo sobre ele para que ele não desanime da missão e que ela possa alcançar o seu objetivo. Essa nova liderança eleita por Javé agirá discretamente em silêncio entre os pobres e enfraquecidos. A missão beneficiará primeiramente às nações. Aqueles e aquelas que vivem em terras estrangeiras como migrantes. Depois contemplará de modo especial os pobres que estão correndo risco de vida, cana rachada e pavio vacilante e por fim a missão atingirá todos os povos da terra. Essa perspectiva traduz a vontade de Deus que é a salvação de toda a humanidade.(AU)
