Greek by Steven Berkoff (1980): The Risky Transformation of Sophocles’ Oedipus Rex into a Love Story

[eng] Can Sophocles’ Oedipus Rex really be transformed into a love story, as in Steven Berkoff’s drama entitled Greek? This article will show that, although Greek may be viewed by some critics as simply a provocative drama by no means intended to justify incest, directors, actors and critics in the end become enthralled by the powerful love story that ensues between Eddy and his wife and mother. This perspective reveals that Berkoff’s adaptation, intended to portray the social degradation of 1980s Great Britain, is in reality a quite risky proposition since it represents a flat denial of the tragic awareness of contemporary men and women. However, if this is the case, the audience, apart from enjoying the performance of Berkoff’s drama, might question, even from a non-fundamentalist perspective within the classical tradition, to what degree it makes sense to take inspiration from a text by Sophocles that precisely illustrates the great tragic awareness of the ancient Greeks.

Greek de Steven Berkoff (1980): L’arriscada conversió de l’Èdip rei de Sòfocles en una love story

[cat] ¿Podem convertir l’Èdip rei de Sòfocles en una història d’amor com ho fa Berkoff a Greek?. Tot i que alguns crítics llegeixen Greek només com un drama provocador que de cap manera intenta justificar l’incest, directors, actors i crítics resten finalment captivats per la impactant història d’amor entre Eddy i la seva esposa-mare. Això demostraria que l’adaptació de Berkoff, pensada per a il·lustrar la degradació social de la Gran Bretanya dels 80s, esdevé una proposta arriscada, car significa negar de fet la consciència tràgica dels homes i dones contemporanis. Tanmateix, si aquest és el cas, lectors i espectadors, a banda de l’indubtable plaer d’assistir a la representació de Greek, poden preguntar-se, fins i tot des d’una perspectiva no fonamentalista de la tradició clàssica, si té sentit inspirar-se en el text de Sòfocles, el qual mostra precisament la gran consciència tràgica dels grecs.

Sevillian transport jars in early colonial America: the case of Santa María La Antigua del Darién (Colombia)

Within the scope of the TECNOLONIAL (HAR2008-02834/HIST) project, an archaeologi- cal and archaeometric research is being conduct- ed in order to clarify and systematize transport jars production in the Iberian peninsula and their distribution abroad, especially to the Americas, from the 15th to the 17th century. The production centre of Seville, in the Crown of Castile, produced large glazed and unglazed transport jars, called botijas, which were mainly devoted to the Atlantic trade network. The pres- ent study accounts for the first results obtained from an initial sample of 34 transport jars dated around the 15th-16th centuries from the produc- tion centre of Seville and the reception site of Santa María de la Antigua del Darién (gulf of Urabá, Colombia). This latter site is especially significant since it was the first Spanish founda- tion (1510) in continental America that obtained the title of town, and was the seat for the Governor of the new region called Castilla de Oro, as well as for the first diocese. All individuals were analyzed by means of x-ray fluorescence and diffraction analyses and then compared with the majolica production database from Seville. The results enabled us to define the first refer- ence groups for such modern transport jars, and to get a first insight into the jars coming to the Americas in the early 16th century whose prove- nance can be linked to Seville, but not Triana.

Radio Frequency Measurement Method for Detecting Bearing Currents in Induction Motors

Induction motors are widely used in industry, and they are generally considered very reliable. They often have a critical role in industrial processes, and their failure can lead to significant losses as a result of shutdown times. Typical failures of induction motors can be classified into stator, rotor, and bearing failures. One of the reasons for a bearing damage and eventually a bearing failure is bearing currents. Bearing currents in induction motors can be divided into two main categories; classical bearing currents and inverter-induced bearing currents. A bearing damage caused by bearing currents results, for instance, from electrical discharges that take place through the lubricant film between the raceways of the inner and the outer ring and the rolling elements of a bearing. This phenomenon can be considered similar to the one of electrical discharge machining, where material is removed by a series of rapidly recurring electrical arcing discharges between an electrode and a workpiece. This thesis concentrates on bearing currents with a special reference to bearing current detection in induction motors. A bearing current detection method based on radio frequency impulse reception and detection is studied. The thesis describes how a motor can work as a “spark gap” transmitter and discusses a discharge in a bearing as a source of radio frequency impulse. It is shown that a discharge, occurring due to bearing currents, can be detected at a distance of several meters from the motor. The issues of interference, detection, and location techniques are discussed. The applicability of the method is shown with a series of measurements with a specially constructed test motor and an unmodified frequency-converter-driven motor. The radio frequency method studied provides a nonintrusive method to detect harmful bearing currents in the drive system. If bearing current mitigation techniques are applied, their effectiveness can be immediately verified with the proposed method. The method also gives a tool to estimate the harmfulness of the bearing currents by making it possible to detect and locate individual discharges inside the bearings of electric motors.

Wood pellet markets in Russia

Bioenergy came to Russia through wood pellets. On account of prevalence of oil and gas in the Russian economy «bioenergy» has come with a great delay. Certainly, there were many woodworking enterprises and even municipal boiler-houses using wood waste and fire wood for energy reception, but this activity was not purposeful. More likely it was connected with necessity of waste recycling and with the organization of heat supply in the remote areas of the country. However, in 2001 was founded the first pellet plant in Russia. The purpose of this work was to analyze wood pellets market in Russia, investigate current situation on the home and export market, evaluates supply and demand development, opportunities for wood pellets manufactures in Russia, the main manufactures in Russian market; cost and prices for wood pellets in Russia. Also the work was intended to give better understanding of the main problems of wood pellets industry in Russia. Besides, this work had updated information about Russian customs and logistic systems.

The master theses are focused on peat, as on ambiguous raw materials for processing and fuel manufacture. The purpose of theses to show how much widely applied peat, technologies on its processing and its influence on environment at all stages of its working out.

Software per al cronometratge de temps mitjançant sensors digitals

L’Slot, conegut per tots amb el nom d’Scalextric, s’ha implantat com a una forma d’oci habitual, la pràctica del qual no queda restringida als més petits, sinó que cada vegada crea més afició entre els grans. El fet que l’Slot s’hagi extès entre els adults n’ha revolucionat la pràctica. L’entrada al mercat de l’Slot de gent adulta, i amb poder adquisitiu molt superior als adolescents, ha provocat que les marques especialitzades vagin evolucionant els seus productes cada vegada més. Totes les marques s’han vist obligades a desenvolupar vehicles més competitius i alhora treure al mercat accessoris que augmentin la realitat del joc. Una de les necessitats que s’ha creat és la de competir entre jugadors. Aquesta competició tan pot ser en forma de carrera entre diversos participants, com de forma individual, cronometrant el temps de cada participant en un circuit. L’objectiu principal del projecte és crear un sistema capaç de realitzar cronometratges en temps real mitjançant sensors digitals ja existents en el mercat de l’Slot i poder controlar i visualitzar la informació des d’un PC. Per a poder captar els senyals dels sensors s’ha utilitzat un sistema microcontrolat, que garanteix gran velocitat d’adquisició, processament de dades i transmissió. La comunicació del Microcontrolador amb el PC s’ha realizat mitjançant el bus USB. El PC serà el controlador del sistema i donarà les ordres al Microcontrolador, podent així tenir control total sobre el funcionament del programa. També serà el PC el que tractarà els crocometratges enregistrats i els mostrarà per pantalla

El plan de lengua y cohesión social en Catañunya: primeros datos de una investigación = Language and Social Cohesion Plan in Catalonia: Initial research data

Los programas de inmersión lingüística han constituido y constituyen dentro del Sistema Educativo catalánla principal forma para que el alumnado de lengua familiar no-catalana aprenda una nueva lengua, el catalán,sin que, en su proceso de aprendizaje, vea mermado ni el desarrollo de su propia lengua ni su rendimientoacadémico. El éxito de la inmersión lingüística en las décadas anteriores ha sido frecuentemente utilizado comouno de los argumentos orientativos para justificar la política lingüística que se sigue en la escolarización de lainfancia extranjera. Sin embargo, los resultados obtenidos por investigaciones recientes parece que no avalanempíricamente dicho argumento. Este artículo analiza dichos resultados y expone, a partir del Plan para laLengua y Cohesión Social puesto en marcha por el Departamento de Educación de la Generalitat de Cataluña,cuáles son los retos que se presentan a su Sistema Educativo dentro del nuevo marco que supone el aumento de ladiversidad cultural y lingüística en la actual sociedad catalana

Digital social media: An interactive technology incorporated as a competitive advantage for business

In a more transparent and dynamic world, in which consumers trust other consumers more for advice and recommendations on products and services, the continuity of organizations appears to be associated with socialization, the sharing of interests and the interaction with the audience. This is associated with the incorporation of digital technologies to business, specifically the use of social media. Consequently, it is timely and interesting to explore the phenomenon of virtual socialization, although it is a littlestudied field and what is needed is an innovative and theoretical approach based upon theories of marketing and communication. Expertise in these areas is present in all organizations and their performance is important for appropriate development of them. This work is a qualitative analysis about the behavior, reactions and attitudes of individuals to organizations, in order to understand the social factors that contribute to sustainable competitive advantages of organizations which can support strategic and future actions. We conclude that relevant factors associated with the tacit knowledge of the organization, specifically to learning and social interaction of the organization and their knowledge of virtual communities. The higher the coexistence of factors, the more difficult is the replication and greater will be the hypothesis of sustainable competitive advantage.

Um sistema microcontrolado para o monitoramento on-line, in situ e remoto de pH, condutividade e temperatura de águas

A portable microcontrolled system is proposed to monitor conductivity, temperature and pH in on-line, in situ and remote way from a water reservoir faraway 200 m. The system comprises two modules: one for data reception (located in laboratory) and another for data acquisition/transmission (located near water reservoir). It uses a microcontroller and a transceiver to remote data transmission/reception by radio frequency. Variations of water parameters were simultaneously monitored without interruption during a period of ten hours with a relative error about 4.0 %. The developed system showed simple, stable, accurate, robust and low-cost to determine parameters of water in field.

O ensino superior de química: reflexões a partir de conceitos básicos para a química orgânica

We live in a context in which knowledge develops continuously and rapidly. This generates a social dynamics that demands constant adaptation from those living in society and also from educational institutions. Education for this new society needs to be rethought. Universities, anchored in tradition, still use a transmission/reception model of education. A data-collecting instrument applied to undergraduate chemistry students at the end of the course in organic chemistry investigated some concepts essential to the education of a chemist, such as interatomic and intermolecular interactions and Lewis structure. We observed that students have difficulty dealing with these concepts, and we believe that this is related to the type of class they had/have and to the way the concepts are presented in the college textbooks.

WOMAN IN CHEMISTRY. JANE MARCET, A RELEVANT FIGURE IN CHEMISTRY EDUCATION

A historiographical study of Jane Marcet’s role in spreading chemistry knowledge to a wider audience in the 19th century is presented here. Her efforts to spread scientific knowledge were crucial to sharing the most important theories of chemistry among different audiences, particularly women and young people. Through her book, “Conversations on Chemistry,” which was published in several editions from 1806 to 1853, she contributed significantly to chemistry education. Despite controversy over the large number of editions, this text is a strong witness to the active participation of women in science. Her scientific rigor and contribution to narrative strategies in chemistry pedagogy have given Jane Marcet consideration not only as an important woman in the scientific community of England during the first half of the 19th century but also as a central figure in the early development of chemistry diffusion and education.

Models and applications for risk assessment and prediction of Asian soybean rust epidemics

Asian rust of soybean [Glycine max (L.) Merril] is one of the most important fungal diseases of this crop worldwide. The recent introduction of Phakopsora pachyrhizi Syd. & P. Syd in the Americas represents a major threat to soybean production in the main growing regions, and significant losses have already been reported. P. pachyrhizi is extremely aggressive under favorable weather conditions, causing rapid plant defoliation. Epidemiological studies, under both controlled and natural environmental conditions, have been done for several decades with the aim of elucidating factors that affect the disease cycle as a basis for disease modeling. The recent spread of Asian soybean rust to major production regions in the world has promoted new development, testing and application of mathematical models to assess the risk and predict the disease. These efforts have included the integration of new data, epidemiological knowledge, statistical methods, and advances in computer simulation to develop models and systems with different spatial and temporal scales, objectives and audience. In this review, we present a comprehensive discussion on the models and systems that have been tested to predict and assess the risk of Asian soybean rust. Limitations, uncertainties and challenges for modelers are also discussed.

Kustannukset ja kannattavuus RFID- ja toiminnanohjausjärjestelmien integrointiprojektissa

Maailmantalouden jyrkkä lasku vuonna 2008 ajoi yritykset säästökuurille. Säästöjä pyritään saamaan esimerkiksi automatisoimalla toimintoja. Yksi tapa luoda kustannussäästöjä on käyttää RFIDteknologiaa varastoinnin toimien tehostukseen. Tämän tutkimuksen pääasiallisena tavoitteena on ollut rakentaa yksinkertainen laskentamalli RFID- ja toiminnanohjausjärjestelmien integrointiprojektin kustannusten ja kannattavuuden laskemiseen. Toisena tavoitteena on ollut selvittää, mitkä tekijät vaikuttavat investoinnin kannattavuuteen. Tutkimus rajattiin tarkastelemaan varaston saapuvan tavaran vastaanoton prosessia ja sen toimintojen automatisointia RFID-järjestelmän avulla. Laskentamalli muodostuu kolmesta osasta: investoinnin kokonaiskustannusten arvioinnista, investoinnista saatavien kustannussäästöjen arvioinnista ja kannattavuuslaskelmista. Investointien kokonaiskustannusten arviointia varten rakennettiin luettelo yleisimmistä kustannuslajeista. Investoinnista saatavien kustannussäästöjen arviointi tehtiin analysoimalla nykyprosesseja ja etsimällä niistä toimintoja, jotka tehostuvat RFID-järjestelmän avulla. Varsinaisina kannattavuuslaskentamenetelminä käytettiin investoinnin takaisinmaksuajan menetelmää sekä pääoman tuottoasteen menetelmää. Tutkimuksen tuloksena todettiin rakennetun laskentamallin soveltuvan hyvin investoinnin kustannusten ja kannattavuuden arviointiin. Samalla havaittiin yrityksen toimialan, saapuvien lähetysten määrän ja lähetysten rivimäärän vaikuttavan merkittävästi RFID- jatoiminnanohjausjärjestelmän integrointiprojektin kannattavuuteen.
