La rehabilitación y el uso del patrimonio histórico industrial

La reutilización de edificios industriales es un aspecto del proceso de reconversión de suelo industrial en otros usos, el cual se ha acentuado con la reestructuración industrial ligada a la aparición de lo que se denomina ciudad postindustrial. Dicho proceso ha llevado con frecuencia al abandono y a la degradación de los viejos edificios industriales, que muchas veces son derribados y sustituidos por otros nuevos dedicados a viviendas o a usos terciarios. En los dos últimos decenios, sin embargo, la conservación y la reutilización del patrimonio histórico industrial ha adquirido una gran importancia. Los viejos edificios industriales funcionalmente obsoletos poseen, en efecto, valores arquitectónicos y técnicos que hacen a veces necesaria y posible su conservación y reutilización adaptativa. Pero eso exige definir claramente criterios de selección, tras un proceso de inventario y catalogación, en el que deben tenerse en cuenta los criterios generales de catalogación del patrimonio histórico monumental. El artículo discute la conveniencia de conservar edificios funcionalmente obsoletos y aborda la cuestión de las estrategias de defensa, haciendo alusión al papel de los técnicos y a la necesidad del compromiso local.

Influência do manejo do solo e da rotação de culturas na qualidade industrial do trigo

A qualidade industrial do trigo é afetada por fatores genéticos e ambientais, como solo, clima, tratos culturais, e outros. O presente trabalho teve como finalidade avaliar o efeito de sistemas de manejo de solo e de rotação de culturas sobre características que definem a qualidade industrial de trigo (peso do hectolitro, peso de mil grãos, extração experimental de farinha, alveografia, teste de microssedimentação com lauril sulfato de sódio e número de queda). O delineamento experimental foi em blocos ao acaso, com parcelas subdivididas e três repetições. A parcela principal foi constituída pelos sistemas de manejo de solo (plantio direto, preparos convencionais de solo com arado de discos e de aivecas, e cultivo mínimo), e a subparcela, pelos sistemas de rotação de culturas (monocultura, um inverno e dois invernos sem trigo). O preparo convencional de solo com arado de discos e o cultivo mínimo reduziu o número de queda; o sistema de rotação com dois invernos sem trigo elevou o peso do hectolitro; a monocultura desse cereal reduziu o peso do hectolitro, elevou a força geral de glúten e a microssedimentação com lauril sulfato de sódio; a interação sistemas de manejo de solo, rotação de culturas e ano de cultivo afetou o peso de mil grãos e, o ano de cultivo teve grande influência em todas as características de qualidade industrial de trigo estudadas.

Relationship between estrogen receptor alpha location and gene induction reveals the importance of downstream sites and cofactors.

BACKGROUND: To understand cancer-related modifications to transcriptional programs requires detailed knowledge about the activation of signal-transduction pathways and gene expression programs. To investigate the mechanisms of target gene regulation by human estrogen receptor alpha (hERalpha), we combine extensive location and expression datasets with genomic sequence analysis. In particular, we study the influence of patterns of DNA occupancy by hERalpha on expression phenotypes. RESULTS: We find that strong ChIP-chip sites co-localize with strong hERalpha consensus sites and detect nucleotide bias near hERalpha sites. The localization of ChIP-chip sites relative to annotated genes shows that weak sites are enriched near transcription start sites, while stronger sites show no positional bias. Assessing the relationship between binding configurations and expression phenotypes, we find binding sites downstream of the transcription start site (TSS) to be equally good or better predictors of hERalpha-mediated expression as upstream sites. The study of FOX and SP1 cofactor sites near hERalpha ChIP sites shows that induced genes frequently have FOX or SP1 sites. Finally we integrate these multiple datasets to define a high confidence set of primary hERalpha target genes. CONCLUSION: Our results support the model of long-range interactions of hERalpha with the promoter-bound cofactor SP1 residing at the promoter of hERalpha target genes. FOX motifs co-occur with hERalpha motifs along responsive genes. Importantly we show that the spatial arrangement of sites near the start sites and within the full transcript is important in determining response to estrogen signaling.

Spatial Exploration of Age Distribution in Catalan Municipalities

This paper takes the shelf and digs into the complex population’s age structure of Catalan municipalities for the year 2009. Catalonia is a very heterogeneous territory, and age pyramids vary considerably across different areas of the territory, existing geographical factors shaping municipalities’ age distributions. By means of spatial statistics methodologies, this piece of research tries to assess which spatial factors determine the location, scale and shape of local distributions. The results show that there exist different distributional patterns across the geography according to specific local determinants. Keywords: Spatial Models. JEL Classification: C21.

Three essays on major trends in a slow clockspeed industry : the case of industrial automation

The motivation for this research initiated from the abrupt rise and fall of minicomputers which were initially used both for industrial automation and business applications due to their significantly lower cost than their predecessors, the mainframes. Later industrial automation developed its own vertically integrated hardware and software to address the application needs of uninterrupted operations, real-time control and resilience to harsh environmental conditions. This has led to the creation of an independent industry, namely industrial automation used in PLC, DCS, SCADA and robot control systems. This industry employs today over 200'000 people in a profitable slow clockspeed context in contrast to the two mainstream computing industries of information technology (IT) focused on business applications and telecommunications focused on communications networks and hand-held devices. Already in 1990s it was foreseen that IT and communication would merge into one Information and communication industry (ICT). The fundamental question of the thesis is: Could industrial automation leverage a common technology platform with the newly formed ICT industry? Computer systems dominated by complex instruction set computers (CISC) were challenged during 1990s with higher performance reduced instruction set computers (RISC). RISC started to evolve parallel to the constant advancement of Moore's law. These developments created the high performance and low energy consumption System-on-Chip architecture (SoC). Unlike to the CISC processors RISC processor architecture is a separate industry from the RISC chip manufacturing industry. It also has several hardware independent software platforms consisting of integrated operating system, development environment, user interface and application market which enables customers to have more choices due to hardware independent real time capable software applications. An architecture disruption merged and the smartphone and tablet market were formed with new rules and new key players in the ICT industry. Today there are more RISC computer systems running Linux (or other Unix variants) than any other computer system. The astonishing rise of SoC based technologies and related software platforms in smartphones created in unit terms the largest installed base ever seen in the history of computers and is now being further extended by tablets. An underlying additional element of this transition is the increasing role of open source technologies both in software and hardware. This has driven the microprocessor based personal computer industry with few dominating closed operating system platforms into a steep decline. A significant factor in this process has been the separation of processor architecture and processor chip production and operating systems and application development platforms merger into integrated software platforms with proprietary application markets. Furthermore the pay-by-click marketing has changed the way applications development is compensated: Three essays on major trends in a slow clockspeed industry: The case of industrial automation 2014 freeware, ad based or licensed - all at a lower price and used by a wider customer base than ever before. Moreover, the concept of software maintenance contract is very remote in the app world. However, as a slow clockspeed industry, industrial automation has remained intact during the disruptions based on SoC and related software platforms in the ICT industries. Industrial automation incumbents continue to supply systems based on vertically integrated systems consisting of proprietary software and proprietary mainly microprocessor based hardware. They enjoy admirable profitability levels on a very narrow customer base due to strong technology-enabled customer lock-in and customers' high risk leverage as their production is dependent on fault-free operation of the industrial automation systems. When will this balance of power be disrupted? The thesis suggests how industrial automation could join the mainstream ICT industry and create an information, communication and automation (ICAT) industry. Lately the Internet of Things (loT) and weightless networks, a new standard leveraging frequency channels earlier occupied by TV broadcasting, have gradually started to change the rigid world of Machine to Machine (M2M) interaction. It is foreseeable that enough momentum will be created that the industrial automation market will in due course face an architecture disruption empowered by these new trends. This thesis examines the current state of industrial automation subject to the competition between the incumbents firstly through a research on cost competitiveness efforts in captive outsourcing of engineering, research and development and secondly researching process re- engineering in the case of complex system global software support. Thirdly we investigate the industry actors', namely customers, incumbents and newcomers, views on the future direction of industrial automation and conclude with our assessments of the possible routes industrial automation could advance taking into account the looming rise of the Internet of Things (loT) and weightless networks. Industrial automation is an industry dominated by a handful of global players each of them focusing on maintaining their own proprietary solutions. The rise of de facto standards like IBM PC, Unix and Linux and SoC leveraged by IBM, Compaq, Dell, HP, ARM, Apple, Google, Samsung and others have created new markets of personal computers, smartphone and tablets and will eventually also impact industrial automation through game changing commoditization and related control point and business model changes. This trend will inevitably continue, but the transition to a commoditized industrial automation will not happen in the near future.

Avaliação agronômica de um biossólido industrial para a cultura do milho

O objetivo deste trabalho foi avaliar a viabilidade agronômica de um biossólido industrial para a cultura do milho. O experimento foi realizado no campo, em um Cambissolo distrófico, nos anos agrícolas 1999/2000 e 2000/2001. A aplicação de 0, 6, 12, 18 e 24 Mg ha-1 de biossólido base seca, suplementado com K2O nos dois anos e 30% do P2O5 recomendado no segundo ano, foi comparada à adubação mineral completa. O biossólido melhorou a fertilidade do solo, o estado nutricional e a produtividade do milho, que apresentou resposta quadrática às doses aplicadas, atingindo a máxima de 9.992 kg ha-1 de grãos com 22,5 Mg ha-1 de biossólido, superando em 21% a adubação mineral e em 74% o controle. Mesmo na maior dose aplicada, os teores de nutrientes, Na e metais pesados no biossólido não causaram fitotoxicidade. A equivalência em produtividade à adubação mineral (7.895 kg ha-1) foi obtida com 10 Mg ha-1 de biossólido. Com base na equivalência ao NPK, o valor do biossólido foi estimado em R$ 43,70 Mg-1 base seca e R$ 8,74 Mg-1 base úmida. Considerando-se o custo de transporte, a aplicação deste biossólido é economicamente viável numa distância de até 66 km da fonte geradora.

Freqüência de irrigação por gotejamento durante o estádio vegetativo do tomateiro para processamento industrial

Objetivo deste trabalho foi o de estabelecer critério para o manejo de água, durante o estádio vegetativo do tomateiro para processamento industrial, nas condições de cerrado do Brasil Central. Foram avaliados seis turnos de rega entre 0,5 e 16 dias. O estande final e a produtividade de frutos, maximizados em regas a cada 2 dias, apresentaram resposta quadrática com a freqüência de irrigação, enquanto a produção de biomassa foi maximizada em regas diárias. A massa média de fruto e o número de frutos por planta não foram influenciados pelos tratamentos; isto indica que as diferenças de produção foram causadas, principalmente, pela variação do estande final. A profundidade efetiva de raízes apresentou resposta linear positiva com o turno de rega. As plantas irrigadas a cada 8 e 16 dias apresentaram um sistema radicular cerca de 10 cm mais profundo do que aquelas irrigadas duas vezes por dia. O teor de sólidos solúveis totais, a acidez titulável e a taxa de fruto podre não foram influenciados pelos turnos de rega. Observou-se que para melhor desempenho do tomateiro, durante o estádio vegetativo as irrigações devem ser realizadas a cada 2 dias, ou seja, quando a tensão de água no solo atingir cerca de 17 kPa.

Location-independent and location-linked representations of sound objects.

For the recognition of sounds to benefit perception and action, their neural representations should also encode their current spatial position and their changes in position over time. The dual-stream model of auditory processing postulates separate (albeit interacting) processing streams for sound meaning and for sound location. Using a repetition priming paradigm in conjunction with distributed source modeling of auditory evoked potentials, we determined how individual sound objects are represented within these streams. Changes in perceived location were induced by interaural intensity differences, and sound location was either held constant or shifted across initial and repeated presentations (from one hemispace to the other in the main experiment or between locations within the right hemispace in a follow-up experiment). Location-linked representations were characterized by differences in priming effects between pairs presented to the same vs. different simulated lateralizations. These effects were significant at 20-39 ms post-stimulus onset within a cluster on the posterior part of the left superior and middle temporal gyri; and at 143-162 ms within a cluster on the left inferior and middle frontal gyri. Location-independent representations were characterized by a difference between initial and repeated presentations, independently of whether or not their simulated lateralization was held constant across repetitions. This effect was significant at 42-63 ms within three clusters on the right temporo-frontal region; and at 165-215 ms in a large cluster on the left temporo-parietal convexity. Our results reveal two varieties of representations of sound objects within the ventral/What stream: one location-independent, as initially postulated in the dual-stream model, and the other location-linked.

Projecte d'adequació d'una nau industrial per a la implantació d'una indústria de processat d'ametlles

El projecte se situa en una explotació agrícola de 20 ha, 18 de les quals estan destinades al cultiu d’ametllers de la varietat Vairo. L’explotació pertany al municipi de l’Albi, a la comarca de Les Garrigues, província de Lleida. Actualment a la finca existeix una nau industrial sense instal•lació elèctrica ni hidràulica i sense cap partició a l’interior que es fa servir com a magatzem d’eines. Les ametlles recollides a l’explotació són comercialitzades a una cooperativa de Reus. Els serveis dels que disposa la finca actualment són: - Escomesa elèctrica a l’entrada de la finca. - Aigua del canal Segarra-Garrigues pressuritzada. Escomesa a l’entrada de la finca. - Fossa sèptica de 50 m3. Es troba a 20 m del col•lector general pel qual s’evacuaran les aigües residuals. Es tracta d’una antiga bassa soterrada que ja existia i que se’n reconvertirà el seu ús. L’objectiu del projecte és descriure i dissenyar l’adequació de la nau industrial de dimensions 10 m x 12 m (120 m2) per implantar una indústria de processat primari d’ametlla. El processat primari consisteix en el desclovat de l’ametlla (separació del gra de la closca), assecat del gra obtingut per aconseguir una humitat inferior al 6 % i finalment l’envasat d’aquest gra. Com a procés secundari s’envasarà i es comercialitzarà la closca obtinguda en el procés de descolvat

Use of Reagent Grade Versus Industrial Grade Trichlorethylene in Asphalt Recoveries, MLR-83-05, 1983

This is a continuation of a project initiated a year ago to determine any differences in test results on recovered asphalt cements caused by the use of industrial grade of solvent as compared with the reagent grade. AASHTO specifies the use of reagent grade of trichlorethylene, but the Laboratory uses industrial grade which costs much less. Last year this objective of the project was aborted when it was found that a larger difference in test results was obtained between the two distillation apparatuses than between the two solvents, Then all efforts were directed toward obtaining uniformity in test results between the apparatuses under the east hood as compared with that under the west hood. Considerable progress was made toward this end. (See report under this same title dated April 1982). The objective this year was to again evaluate the results when using both variables (apparatuses and solvents). Another objective developed later in this investigation; this was to determine any differences in test results on recovered asphalt cements caused by the use of reclaimed trichlorethylene (from the distillation process) as compared with the use of industrial grade of solvent. At the present time the reclaimed trichlorethylene is discarded. If the reclaimed solvent could be used for further recoveries, a considerable savings in solvent costs would result.
