Three decades of Space Activities at the Instituto Universitario de Microgravedad "Ignacio Da Riva" / Universidad Politécnica de Madrid (IDR/UPM) en History of Rocketry and Astronautics

Strictly speaking, space related activities at the Escuela Técnica Superior de Ingenieros Aeronáuticos (ETSIA) begun in 1973, when Prof. Ignacio Da Riva got a contract from the European Space Agency (ESA) to compile a handbook on spacecraft thermal control. By the same time, ESA issued an announcement of opportunities offering to the European scientific community the possibility of perform microgravity relevant experiments on board space platform like the European orbital laboratory Spacelab. Prof. Da Riva proposed one of the few selected experiments dealing with fluid physics under microgravity conditions, later flown on Spacelab-1 mission in 1983. These two events were the starting point where Prof. Da Riva, full professor of Aerodynamics at ETSIA, nucleated a small group of young professors and students located at the Laboratorio de Aerodinámica y Mecánica de Fluidos (LAMF) of ETSIA. Such group was leaded by Prof. Da Riva since its creation till 1991, when Prof. Da Riva died, and it was the seed of the more recently created research institute for aerospace science and technology named "Ignacio Da Riva" (IDR) in his honour. In this communication space related activities performed either at LAMF or IDR during the last three decades are briefly described.

Growth and development of three key summer grasses in Australian cotton systems

Awnless barnyard grass, feathertop Rhodes grass, and windmill grass are important weeds in Australian cotton systems. In October 2014, an experiment was established to investigate the phenological plasticity of these species. Seed of these species were planted in a glasshouse every four weeks and each cohort grown for 6 months. A developmental response to day length was observed in barnyard grass but not in the other species. Days to maturity increased with each planting for feathertop Rhodes and windmill grass for the first six cohorts. Barnyard grass showed a similar pattern in growth for seeds planted from October to December with an increase in the onset of maturity from 51 to 58 days. However, the onset of maturity for cohorts planted between January and March decreased to between 50 and 52 days. All species had a decrease in the total number of panicles produced from the first four plantings. Feathertop Rhodes grass planted in October produced 41 panicles compared to those planted at the end of December producing 30 panicles, barnyard grass had a decrease from 99 to 47 panicles and windmill grass 37 to 15 panicles on average. By comparing the development of these key weed species over 12 months, detailed information on the phenological plasticity of these species will be obtained. This information will contribute to more informed management decisions by improving our understanding of appropriate weed control timings or herbicide rates depending on weed emergence and development.

Performance space to performance place

The focus of this paper questions how the performance place was transformed to a performance space. This major change in distinction holds an ongoing significance to the development of the actors, scenographers, animators, writers and film directors craft within current digitally mediated and interactive performance environments. As part of this discussion this paper traces the crucial seed of the revolution that transformed modern scenographic practice from the droll of the romantic realism of the Victorian stage to the open potential of the performance environment of today. This is achieved through close readings on the practical work of Edward Gordon Craig and Adolphe Appia as well as the scenographic discussions of Chris Baugh.

Biopharming the SimpliRED™ HIV diagnostic reagent in barley, potato and tobacco

This is the first report of an antibody-fusion protein expressed in transgenic plants for direct use in a medical diagnostic assay. By the use of gene constructs with appropriate promoters, high level expression of an anti-glycophorin single-chain antibody fused to an epitope of the HIV virus was obtained in the leaves and stems of tobacco, tubers of potato and seed of barley. This fusion protein replaces the SimpliRED™ diagnostic reagent, used for detecting the presence of HIV-1 antibodies in human blood. The reagent is expensive and laborious to produce by conventional means since chemical modifications to a monoclonal antibody are required. The plant-produced fusion protein was fully functional (by ELISA) in crude extracts and, for tobacco at least, could be used without further purification in the HIV agglutination assay. All three crop species produced sufficient reagent levels to be superior bioreactors to bacteria or mice, however barley grain was the most attractive bioreactor as it expressed the highest level (150 μg of reagent g-1), is inexpensive to produce and harvest, poses a minuscule gene flow problem in the field, and the activity of the reagent is largely undiminished in stored grain. This work suggests that barley seed will be an ideal factory for the production of antibodies, diagnostic immunoreagents, vaccines and other pharmaceutical proteins.

DroplIT, an improved image analysis method for droplet identification in high-throughput crystallization trials

The application of robotics to protein crystallization trials has resulted in the production of millions of images. Manual inspection of these images to find crystals and other interesting outcomes is a major rate-limiting step. As a result there has been intense activity in developing automated algorithms to analyse these images. The very first step for most systems that have been described in the literature is to delineate each droplet. Here, a novel approach that reaches over 97% success rate and subsecond processing times is presented. This will form the seed of a new high-throughput system to scrutinize massive crystallization campaigns automatically. © 2010 International Union of Crystallography Printed in Singapore-all rights reserved.

Controlled pollination methods for creating Corymbia hybrids.

Inter-specific Corymbia hybrids are of increasing interest to plantation forestry, yet there is little knowledge of the most suitable controlled pollination methods for this genus. Inter-specific crosses were made between C. torelliana [CT(maternal parent)] and C. citriodora subsp. variegata (CCV), C. henryi (CH) and C. citriodora subsp. citriodora (CCC) using conventional pollination, one-stop pollination (OSP) and artificially-induced protogyny on yellow buds (AIP Y) pollination methods. Additional treatments included AIP on green buds (AIP G) and the use of exclusion bags for the OSP and AIP methods. Inter-specific hybrids (CT x CCV, CT x CH and CT x CCC) were successfully created using all three pollination methods. The AIP Y treatment provided the highest seed yields and achieved time savings of >41% over the conventional and OSP methods, resulting in up to five-fold increases in operator productivity. However, the AIP Y treatment also had the highest C. torelliana contamination levels (9.3–13.2%). The use of exclusion bags with the AIP method had minimal effect on contamination rates, indicating a high proportion of selfpollen contamination. Contamination rates varied between maternal parents, suggesting variation in selfcompatibility for C. torelliana individuals. AIP using semi-ripe green buds was not effective at reducing selfing and had low operator productivity. The AIP method is suitable for use in a large-scale hybrid breeding program for C. torelliana. When self-pollination effects are managed, it could greatly reduce the costs associated with the production of seed of elite family crosses for commercial forestry deployment.

There is 'hope for you yet': The female drug offender in sentencing discourse

Language and gender research has, in recent years, emphasised the importance of examining the context-specific ways in which people ‘do gender’ in different situations. In this paper, we explore how women involved in drug offences, specifically methamphetamine manufacture offences, are constructed within the language of the courts. Thirty-six sentencing transcripts from the New Zealand courts were examined to investigate how such offences, committed by women, are understood. In order to explore the representation of female offenders, a critical discourse analytic approach was adopted. Such an approach recognises that linguistic modes not only create and legitimise power inequalities but also embody a specific worldview. Three gendered discourses were identified in the sentencing texts: (i) the discourse of femininity, reinforcing the socially prescribed female role; (ii) the discourse of aberration, concerning women who breach traditional gender role expectations, and; (iii) the discourse of salvation, presenting aberrant women with an opportunity to become ‘good’ women once again. The findings illustrate the ways in which processes of gendering take place within a specific community of practice: the courtroom.

Pappi ja Raamattu : Suomen evankelis-luterilaisen kirkon pappien suhde Raamattuun

The Pastor and the Bible: Finnish Evangelical Lutheran Pastors Relationship with the Bible Since 1970s there has been extensive discussion in Finland about questions relating to the interpretation of the Bible. The themes of this discussion have focused on the trustworthiness and authority of the Bible, and the discussion has attracted participation not only from representatives of the Evangelical Lutheran Church of Finland but also from representatives of the academic community. The discussion has resulted in extensive publication on the relation of postmodern theology to the Bible. Despite this debate and the texts that have been produced, there is little empirical data on how Evangelical Lutheran pastors with theological education view the Bible. In the present study, 22 pastors of the Evangelical Lutheran Church of Finland were interviewed about how they defined their relationship with the Bible. The interview material was analyzed by means of data-based content analysis. The analysis showed, first, that the pastors viewed the Bible as a mirror of the spiritual growth that they had experienced in the past. Second, the Bible was viewed as a source in the interpretation of matters of faith. The third theme concerned the pastors key experiences in their relationship with the authority of the Bible. The time periods that were significant in defining pastors spiritual growth and past perspective on the Bible included childhood, youth, the period of theological education, and the time spent as a pastor. In childhood, the Bible was part of the spiritual atmosphere of the home, and parents and grandparents made a crucial contribution to the child s emerging view of the Bible. In childhood, the Bible was essentially the Old Testament and its exciting stories. In youth, reading the Bible became more personal, and the teachings of Jesus began to take on a more central role. In youth, most of the interviewees had strong experiences of faith and began to view the Bible as an absolute and divine source of dogma. The period of theological studies meant a change in their relationship with the Bible and particularly, revelation of the human aspects of the Bible. These changes were associated with a deepening of belief in the Bible and also a painful crisis in questions related to the trustworthiness of the Bible. For many of the interviewees, their relationship with the Bible changed also when they started their work as pastors. When faced with a call to work as a pastor, the interviewees created a synthesis of the secure faith that they had experienced in their childhood and the more critical views with which they had become acquainted during their theological education. Pastorhood meant the beginning of public teaching of the Bible. The interviewees felt that, in this new role, they discovered again - but now in a deeper sense - the trustworthiness in the bible that they had experienced during their childhood. Based on the interviewees experiences during the periods mentioned above, five different interpretations were formed regarding how the interviewed pastors viewed their past relationship with the Bible. These interpretations were detachment from literal interpretation of the Bible (1), changes in their relationship with the Bible arising from experiences of faith (2), a slow process during which their relationship with the Bible became more human (3), overcoming hardships (4), and no change in their relationship with the Bible (5). In interpretations 1-3, the past was described as a linear development and journey towards a more coherent relationship with the Bible. Interpretations 4-5, in turn, reflected a desire to detach oneself from the perspectives of linear development and change and, instead, emphasize the immutable and process-like nature of one s relationship with the Bible. Concerning the Bible as a source in matters of faith, a conspicuous aspect of the interviews was that all pastors wanted to disconnect themselves from a fundamentalistic view of the Bible, regarding this as an intellectually dishonest relationship with the Bible. On the other hand, none of the interviewees supported a totally relativist view of the Bible. Instead, all interviewees regarded the Bible as a vital source for both them and the Evangelical Lutheran Church. Between the two poles of extremely fundamental and extremely relativistic views, four different categories of viewing the Bible emerged from the interviews: absolute truth (a), a book about the message of salvation (b), a book about holiness and generous love (c), and a source of inspiration (d). The views in categories (a) and (b) emphasized the divine nature of the Bible. According to the pastors who expressed these views, the Bible contains a clear and trustworthy message of God. The views in categories (c) and (d), in turn, emphasized the human aspects of the Bible. The pastors who expressed these views regarded the Bible as a collection of books that was born in a specific historical and cultural context and includes material characteristic to this time. Due to the time-bound nature of the Bible, each generation has to update its view of the Bible. The views in categories (c) and (d) arose from human reality. Comparisons of the views in the different categories indicated that despite their obvious differences, they also shared some common features. The views in categories (a) and (d) shared the common feature of absoluteness, which was seen in category (a) as an emphasis on dogmatism and in category (d) as an emphasis on rationalism. The views in categories (b) and (c), in turn, shared the common feature of a flexible and dynamic relationship with the Bible. The key experiences that appeared to characterize pastors relationship with the authority of the Bible were a joy that arises from self-evidence, awakening to confusion, fear of openness, falling back upon paradoxes, and new confidence. These experiences reveal the circular nature of the process that was common to all interviewees interpretation of their relationship with the Bible. That is, the interviewees experiences of their relationship with the Bible seem to go through a circular process that is activated again and again in new life events. It is like a journey from self-evidence towards critical questions and again back to new confidence. The interview material showed, hence, that relationship with the Bible are characterized by a process that involves experiences of trust, questioning and new trust. The present study brings out the multifaceted reality of pastors relationship with the Bible. The study breaks down contradictions between conservative and liberal views of the Bible by showing how representatives of these opposing poles share commonalities in their attitudes. The study points to a close association between an individual s life history and his or her relationship with the Bible, and lays the groundwork for future studies to investigate the relation between personality and view of the Bible.

La percepción de los valores morales

Resumen: El autor aborda un tema que a veces pasa inadvertido aun para muchos adherentes al iusnaturalismo: el conocimiento de la ley natural. Mientras abundan estudios que centran sus argumentos en la existencia de esta normativa supra positiva o que ahondan su ontología y extensión, sin embargo a veces no se repara en una cuestión liminar que resulta necesario dilucidar: ¿cómo se conocen los principios y las conclusiones de la ley natural?, ¿es naturalmente conocida?, ¿qué se entiende por “naturalmente”? Sobre el contenido de la ley natural el documento afirma que “no es un conjunto cerrado y completo de normas morales, sino la fuente de inspiración constante, presente y operativa de las diversas etapas de la economía de la salvación”. El término “percepción” hace referencia a una “experiencia” y que por tanto es exterior. Se concluye entonces que consiste en un conocimiento objetivo (no innato) de los preceptos morales, más allá de la presencia natural de un hábito que permite su captación (sindéresis).

Laudato Si' : uma abordagem teológica

Resumen: Mario de França Miranda nos propone en su artículo tomar cuenta de la importancia teológica del cuidado de nuestra casa común. Olvidar la importancia de tratar a la naturaleza con respeto brota de una crisis que arraiga en una pérdida de sentido en el designio salvífico que ha sido pronunciado sobre el hombre. Designio que abraza a todo el cosmos.

High-conversion-efficiency and broadband tunable femtosecond noncollinear optical parametric amplifier

We build a compact high-conversion-efficiency and broadband tunable noncollinear optical parametric amplifier (OPA) in the infra-red (IR) pumped by a femtosecond Ti:sapphire CPA laser. The OPA consists of an internal seed of white-light continuum generator (WLG) and two noncollinear optical parametric amplifiers. The tunable wavelength range is from 1.2 mu m to 2.4 mu m for both signal and idle pulses. The total OPA efficiency in the last OPA stage reaches about 40% in a wider tunable spectral range (from 1.3 mu m to 1.7 mu m for signal pulse, from 1.5 mu m to 2.0 mu m for idle pulse respectively).

A representação da Educação Física na mídia televisiva

Esta pesquisa foca a imagem profissional do professor de educação física, considerando a notoriedade que essa profissão adquiriu na televisão ao longo dos últimos anos. O objetivo é explicitar alguns dos sentidos relacionados à abordagem da educação física presente no contexto de duas programações exibidas pela Rede Globo de televisão. A primeira foi retirada da décima oitava temporada da telenovela Malhação, e a segunda do quadro MEDIDA CERTA/ 90 DIAS PARA REPROGRAMAR O CORPO exibido pelo programa Fantástico no ano de 2011. A coleta dos dados ocorreu através do acesso ao site da emissora, que disponibiliza por um determinado tempo, os capítulos da telenovela, bem como as edições do quadro em foco. O método utilizado para nortear a análise do processo de produção dos sentidos foi o referencial teórico da Análise do Discurso segundo a perspectiva de Orlandi. Esse método nos permite percorrer trajetórias capazes de evidenciar sentidos explícitos e implícitos coexistentes no discurso. Assim foram trilhados caminhos específicos para compreensão de cada fenômeno, ou seja, para os dados retirados de Malhação lançamos mão da transcrição de diálogos, apresentação de cenas e consideração dos planos de câmera utilizados em sua produção. Para os dados provenientes do quadro MEDIDA CERTA, realizamos transcrição de falas e construímos categorias, que foram analisadas a partir de uma grade já existente, considerando o título, quem fala, o que é dito, o intermediário e as estratégias utilizadas para publicação do discurso. Quanto aos resultados, foi possível evidenciar que os sentidos relativos à educação física presentes na décima oitava temporada de Malhação foram inspirados basicamente no paradigma competitivo da área. Também foram conservados estereótipos ultrapassados acerca do profissional e da profissão, pois, os sentidos relativos ao professor de educação física idoso foram reduzidos à potencialização de características ligadas à desatualização. E no que confere aos resultados obtidos com a análise do segundo fenômeno, clarificamos que a educação física foi abordada com a utilização do discurso científico, a partir de estratégias pautadas no exemplo testado pelos jornalistas, e oferecidos aos telespectadores. A proposta presente no quadro MEDIDA CERTA colaborou para o entendimento de uma educação física baseada na perspectiva biológica, que se estabelece frente à imposição de um risco ao sujeito, se valorizando como fonte de salvação e encontrando-se fragmentada das questões sociais. As análises de ambos os fenômenos evidenciam significados que permeiam a educação física representada na mídia no atual momento histórico, propiciando também reflexões sobre alguns dos princípios que regem a elaboração de práticas corporais no âmbito da educação física.
