Avaluació de la futura gestió i utilització de la biomassa forestal mitjançant un district heating a Bellver de Cerdanya

En aquest article es pretén explicar breument la viabilitat de la futura gestió i utilització de la biomassa forestal de Bellver de Cerdanya mitjançant un district heating al futur barri del Pla de Tomet. Les particularitats per les quals aquest poble és ideal per a aquest projecte són que l'ajuntament és propietari de gairebé un 90% dels boscos situats en aquest municipi; i que alhora ja ha realitzat diverses instal·lacions que utilitzen la biomassa forestal per a calefacció i ACS. La situació econòmica de la comarca és bastant complicada, ja que s'ha basat en el sector turístic i la construcció, però ambdós no passen pel millor moment. El projecte serviria per donar un valor a la biomassa forestal que fins ara no s'ha donat, i alhora s'intenta buscar nous inputs econòmics per a la Cerdanya. En aquest treball també s'analitza quins haurien de ser els futurs tractaments que s'haurien d'aplicar a la forest, tenint en compte les activitats que es realitzen actualment, i evitant en tot moment possibles efectes negatius, com podria ser la sobreexplotació. També es dedica una part del projecte a explicar els sistemes per obtenir i gestionar de forma correcta la biomassa. A continuació es tracta la part més tècnica, realitzant una estimació del possible futur consum energètic del barri del Pla de Tomet, encara no construït; i decidint quins sistema de calderes seria el més adequat, el tipus d’emmagatzematge més apropiat i els passos a seguir per millorar el rendiment del procés de la gestió i extracció de la biomassa. Seguint tots aquests passos s'arriba a la conclusió que aprofitar la biomassa forestal és millor solució que utilitzar combustibles fòssils. A part dels obvis beneficis medi ambientals, també és millor a nivell econòmic, tant pels futurs veïns com per l'ajuntament.

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.

Issue review : school district cash reserve levy.

During the recent economic crisis, school district budgets have been impacted by state school aid funding shortfalls and state aid reductions due to across-the-board general fund reductions in fiscal year 2009 and fiscal year 2010. Additionally, in fiscal year 2011, the state school aid appropriation was capped and was 156.1 million dollars short of fully funding the state portion of the school aid formula. This issue review examines the impact that the reductions in state aid have had on school district cash reserve levies.

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.
