Per tal d'esquematitzar tota aquesta informació he confeccionat una taula amb els punts forts i punts febles de cada aplicació per concloure amb la proposta de millores per a cada un dels gestors de medis.

Resposta de plantas micropropagadas de abacaxizeiro à inoculação de bactérias diazotróficas em casa de vegetação

O objetivo deste trabalho foi selecionar e avaliar bactérias diazotróficas isoladas de abacaxizeiro (Ananas comosus (L.) Merril) no desenvolvimento de cultivares micropropagadas da mesma espécie em casa de vegetação. Plantas da cultivar Perolera foram submetidas à inoculação com Asaia bogorensis (AB219) e cultivadas em tubetes, durante 145 dias, com as misturas: casca de arroz carbonizada, folha de carnaubeira triturada e vermicomposto; casca de arroz carbonizada, pó da casca do coco maduro e vermicomposto; casca de arroz carbonizada, vermiculita e vermicomposto. Plantas da cultivar Primavera receberam inóculos com o AB219 e bactérias relacionadas a Burkholderia cepacia (AB202 e AB213), enquanto plantas das cultivares Pérola e Smooth Cayenne receberam AB219 e AB213, sendo cultivadas, por 140 dias, em tubetes com a mistura de vermicomposto e vermiculita. A colonização dos abacaxizeiros pelas bactérias diazotróficas foi confirmada. As plantas da cultivar Perolera cresceram melhor em casca de arroz carbonizada, vermiculita e vermicomposto e responderam positivamente ao AB219. Já as plantas da cultivar Primavera não apresentaram resposta significativa à inoculação com AB219, AB202 e AB213. Houve incremento de 23,1% a 38,5% na matéria seca de raízes das plantas da cultivar Pérola na presença de AB213 e AB219, respectivamente. A presença de AB213 incrementou em 15,2% a matéria seca da parte aérea das plantas da cultivar Smooth Cayenne. Os resultados revelam a eficiência de bactérias diazotróficas na promoção do crescimento de abacaxizeiros.

Resposta do arroz em casa de vegetação a fontes de micronutrientes de diferentes granulometria e solubilidade

A granulometria e a solubilidade do fertilizante podem resultar em maior ou menor efeito da adubação. O objetivo deste trabalho foi comparar o efeito de um produto comercial granulado e moído de micronutrientes, com uma mistura de igual composição feita com materiais pró-análise. O delineamento experimental foi o inteiramente casualizado, utilizando três produtos com micronutrientes e quatro doses de cada mistura (0, 14, 28 e 56 mg dm-3), com quatro repetições. A maior produção de grãos é obtida com a aplicação do produto comercial em pó. A melhor correlação entre os materiais e teor na planta ocorre em razão do zinco.

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.

Efeitos do glifosato sobre microrganismos simbiotróficos de soja, em meio de cultura e casa de vegetação

Os efeitos do herbicida Roundup, formulado à base de glifosato, foram avaliados sobre três estirpes de Bradyrhizobium elkanii (BR 29, INPA 80A e INPA 553A), e uma de B. japonicum (BR 86), e sobre três espécies de fungos micorrízicos arbusculares (FMA) (Gigaspora margarita, Glomus etunicatum e Scutellospora heterogama), em meios de cultivo com concentrações crescentes do herbicida (0 a 454 µmol L-1); foram também avaliados os efeitos sobre a nodulação e micorrização da soja, em casa de vegetação, em solo que recebeu, antes da semeadura, doses do herbicida equivalentes a 1,25 até 10 L ha-1. O Roundup mostrou-se inibitório ao crescimento de Bradyrhizobium spp. e aos fungos em meio de cultura, e esse efeito foi crescente com o aumento das concentrações aplicadas, tendo variado em razão das espécies ou estirpes avaliadas. No entanto, a inibição in vitro só ocorreu em concentrações muito superiores à dose recomendada para aplicações no campo. As estirpes BR 29, INPA 553A e INPA 80A mostraram-se mais tolerantes ao glifosato, em relação à estirpe BR 86. O efeito do herbicida sobre a germinação e o crescimento dos tubos germinativos dos esporos dos FMA foi diferenciado, tendo sido observada inibição decrescente de G. etunicatum para S. heterogama e G. margarita. A aplicação do herbicida ao solo, antes da semeadura, até a dose equivalente a 10 L ha-1 não influenciou na nodulação e na colonização micorrízica da soja.

Embryo rescue from interspecific crosses in apple rootstocks

The objetive of this work was to rescue immature embryos of apple rootstocks Malus prunifolia (Marubakaido) and Malus pumila (M9) after 40-60 days of pollination and to put them into MS culture media supplemented with agar (6 g L-1) and casein hydrolysate (500 mg L-1). Embryos originated from interspecific crosses and open pollination showed differences in the in vitro responses, depending on the female parent, the developmental stage of the embryo, and the culture medium composition. Embryos of the M. pumila rootstock, rescued within 40 days after pollination and put in culture medium supplemented with indolacetic acid (IAA), gibberellic acid (GA3), kinetin and maltose, resulted in a normal development of plantlets. However, embryos originating from hand-pollination, cultivated in medium supplemented with 14 µM IAA, 5 µM kinetin and 1.5 µM Ga3 (MS1), mainly those of M. prunifolia x M. pumila, showed a high percentage of rusted embryos (96.2%). Embryos from open pollination of M. prunifolia and M. pumila formed calluses. It was possible to identify the influence of the female parent by the enhanced development of M. pumila shoots derived from open or hand-pollination. The crossing of responsive species and the use of the technique of embryo culture provided a rapid and uniform germination and, consequently, the development of fully normal seedlings.

Tarracomap: Development of an archaeological application on Google Maps navigation System

This paper describes the result of a research about diverse areas of the information technology world applied to cartography. Its final result is a complete and custom geographic information web system, designed and implemented to manage archaeological information of the city of Tarragona. The goal of the platform is to show on a web-focused application geographical and alphanumerical data and to provide concrete queries to explorate this. Various tools, between others, have been used: the PostgreSQL database management system in conjunction with its geographical extension PostGIS, the geographic server GeoServer, the GeoWebCache tile caching, the maps viewer and maps and satellite imagery from Google Maps, locations imagery from Google Street View, and other open source libraries. The technology has been chosen from an investigation of the requirements of the project, and has taken great part of its development. Except from the Google Maps tools which are not open source but are free, all design has been implemented with open source and free tools.

Top manta: escenario actual y perspectiva de futuro

1. Como consecuencia de la LO 5/2010 se ha introducido en el art. 270 CP un segundo párrafo, con el objeto de solucionar los supuestos conocidos como “top manta”, esto es, venta callejera de CD y DVD reproducidos ilegalmente. Para un creciente sector de la doctrina3 y la jurisprudencia tales supuestos eran (o debían ser) atípicos, por tres razones: a) se trataría de supuestos en los que el perjuicio ocasionado al titular de los derechos de explotación de la obra es reducido, dado el escaso número de copias que se distribuyen (principios de proporcionalidad, fragmentariedad y subsidiariedad del Derecho penal con respecto al Derecho administrativo);4 b) el concepto de distribución previsto en el art. 19 LPI no comprende la venta al detalle, sino sólo la distribución a gran escala, por lo que es necesaria una mínima estructura organizativa que en los casos de top manta no concurre;5 c) ausencia de engaño en el consumidor, dado el carácter burdo de las copias.
