In vitro biomechanical comparison of six different fixation methods following 5-mm sagittal split advancement osteotomies

The sagittal split ramus osteotomy (SSRO) is a surgical technique used widely to treat many congenital and acquired mandibular discrepancies. Stabilization of the osteotomy site and the potential for skeletal relapse after the procedure are still major problems. The aim of this study was to compare the mechanical stability of six methods of rigid fixation in SSRO using a biomechanical test model. Sixty polyurethane replicas of human hemimandibles were divided into six groups. In group I, the osteotomies were fixed with two four-hole titanium miniplates; in group II, with one four-hole miniplate; in group III, with one four-hole miniplate + a bicortical screw; in group IV, with a grid miniplate; in group V, with a four-hole locking miniplate; and in group VI, with a six-hole miniplate. A linear load in the premolar region was applied to the hemimandibles. The resistance forces (N) needed to displace the distal segment by 1, 3, and 5 mm were recorded and the data transmitted from the load cell to a computer. One-way analysis of variance with Tukey's post hoc test was performed to compare the means between groups. For the three displacement conditions, there was a strong tendency for the 2.0-mm plate + screw and the grid plate to have higher values.

One-dimensional point interaction with Griffiths' boundary conditions

Griffiths proposed a pair of boundary conditions that define a point interaction in one dimensional quantum mechanics. The conditions involve the nth derivative of the wave function where n is a non-negative integer. We re-examine the interaction so defined and explicitly confirm that it is self-adjoint for any even value of n and for n = 1. The interaction is not self-adjoint for odd n > 1. We then propose a similar but different pair of boundary conditions with the nth derivative of the wave function such that the ensuing point interaction is self-adjoint for any value of n.

Upgrading of Transmission Lines in Areas of Severe Environmental Constraints

The need for increasing the loading capacity of transmission lines in a traditional way, by replacing or reinforcement of the structures and foundations on routes crossing areas considered of permanent environmental preservation, may require additional works that alter the environment. The present rigorous environmental legislation turns these changes and substitution unfeasible. One way to increase the capacity of these lines is the use of new conductor technology. The aim of this paper is to discuss the needs for upgrading a transmission line and minimize or eliminate the damage to the environment by using special conductors. Because the aluminum conductor composite reinforced technology is relatively new and considering the lack of information related to its effective performance in practical system, there is a need to verify the behavior of these conductors through monitoring procedures.

Quantum Correlations in Field Theory and Integrable Systems

In this thesis we will investigate some properties of one-dimensional quantum systems. From a theoretical point of view quantum models in one dimension are particularly interesting because they are strongly interacting, since particles cannot avoid each other in their motion, and you we can never ignore collisions. Yet, integrable models often generate new and non-trivial solutions, which could not be found perturbatively. In this dissertation we shall focus on two important aspects of integrable one- dimensional models: Their entanglement properties at equilibrium and their dynamical correlators after a quantum quench. The first part of the thesis will be therefore devoted to the study of the entanglement entropy in one- dimensional integrable systems, with a special focus on the XYZ spin-1/2 chain, which, in addition to being integrable, is also an interacting model. We will derive its Renyi entropies in the thermodynamic limit and its behaviour in different phases and for different values of the mass-gap will be analysed. In the second part of the thesis we will instead study the dynamics of correlators after a quantum quench , which represent a powerful tool to measure how perturbations and signals propagate through a quantum chain. The emphasis will be on the Transverse Field Ising Chain and the O(3) non-linear sigma model, which will be both studied by means of a semi-classical approach. Moreover in the last chapter we will demonstrate a general result about the dynamics of correlation functions of local observables after a quantum quench in integrable systems. In particular we will show that if there are not long-range interactions in the final Hamiltonian, then the dynamics of the model (non equal- time correlations) is described by the same statistical ensemble that describes its statical properties (equal-time correlations).

Optisch detektierte Magnetresonanz an NV-Zentren in Diamant

Die rasante Entwicklung der Computerindustrie durch die stetige Verkleinerung der Transistoren führt immer schneller zum Erreichen der Grenze der Si-Technologie, ab der die Tunnelprozesse in den Transistoren ihre weitere Verkleinerung und Erhöhung ihrer Dichte in den Prozessoren nicht mehr zulassen. Die Zukunft der Computertechnologie liegt in der Verarbeitung der Quanteninformation. Für die Entwicklung von Quantencomputern ist die Detektion und gezielte Manipulation einzelner Spins in Festkörpern von größter Bedeutung. Die Standardmethoden der Spindetektion, wie ESR, erlauben jedoch nur die Detektion von Spinensembles. Die Idee, die das Auslesen von einzelnen Spins ermöglich sollte, besteht darin, die Manipulation getrennt von der Detektion auszuführen.rn Bei dem NV−-Zentrum handelt es sich um eine spezielle Gitterfehlstelle im Diamant, die sich als einen atomaren, optisch auslesbaren Magnetfeldsensor benutzen lässt. Durch die Messung seiner Fluoreszenz sollte es möglich sein die Manipulation anderer, optisch nicht detektierbaren, “Dunkelspins“ in unmittelbarer Nähe des NV-Zentrums mittels der Spin-Spin-Kopplung zu detektieren. Das vorgeschlagene Modell des Quantencomputers basiert auf dem in SWCNT eingeschlossenen N@C60.Die Peapods, wie die Einheiten aus den in Kohlenstoffnanoröhre gepackten Fullerenen mit eingefangenem Stickstoff genannt werden, sollen die Grundlage für die Recheneinheiten eines wahren skalierbaren Quantencomputers bilden. Die in ihnen mit dem Stickstoff-Elektronenspin durchgeführten Rechnungen sollen mit den oberflächennahen NV-Zentren (von Diamantplatten), über denen sie positioniert sein sollen, optisch ausgelesen werden.rnrnDie vorliegende Arbeit hatte das primäre Ziel, die Kopplung der oberflächennahen NV-Einzelzentren an die optisch nicht detektierbaren Spins der Radikal-Moleküle auf der Diamantoberfläche mittels der ODMR-Kopplungsexperimente optisch zu detektieren und damit entscheidende Schritte auf dem Wege der Realisierung eines Quantenregisters zu tun.rn Es wurde ein sich im Entwicklungsstadium befindende ODMR-Setup wieder aufgebaut und seine bisherige Funktionsweise wurde an kommerziellen NV-Zentrum-reichen Nanodiamanten verifiziert. Im nächsten Schritt wurde die Effektivität und Weise der Messung an die Detektion und Manipulation der oberflächennah (< 7 nm Tiefe) implantieren NV-Einzelzenten in Diamantplatten angepasst.Ein sehr großer Teil der Arbeit, der hier nur bedingt beschrieben werden kann, bestand aus derrnAnpassung der existierenden Steuersoftware an die Problematik der praktischen Messung. Anschließend wurde die korrekte Funktion aller implementierten Pulssequenzen und anderer Software-Verbesserungen durch die Messung an oberflächennah implantierten NV-Einzelzentren verifiziert. Auch wurde der Messplatz um die zur Messung der Doppelresonanz notwendigen Komponenten wie einen steuerbaren Elektromagneten und RF-Signalquelle erweitert. Unter der Berücksichtigung der thermischen Stabilität von N@C60 wurde für zukünftige Experimente auch ein optischer Kryostat geplant, gebaut, in das Setup integriert und charakterisiert.rn Die Spin-Spin-Kopplungsexperimente wurden mit dem sauerstoffstabilen Galvinoxyl-Radikalals einem Modell-System für Kopplung durchgeführt. Dabei wurde über die Kopplung mit einem NVZentrum das RF-Spektrum des gekoppelten Radikal-Spins beobachtet. Auch konnte von dem gekoppelten Spin eine Rabi-Nutation aufgenommen werden.rn Es wurden auch weitere Aspekte der Peapod Messung und Oberflächenimplantation betrachtet.Es wurde untersucht, ob sich die NV-Detektion durch die SWCNTs, Peapods oder Fullerene stören lässt. Es zeigte sich, dass die Komponenten des geplanten Quantencomputers, bis auf die C60-Cluster, für eine ODMR-Messanordnung nicht detektierbar sind und die NV-Messung nicht stören werden. Es wurde auch betrachtet, welche Arten von kommerziellen Diamantplatten für die Oberflächenimplantation geeignet sind, für die Kopplungsmessungen geeignete Dichte der implantierten NV-Zentren abgeschätzt und eine Implantation mit abgeschätzter Dichte betrachtet.

Electron transport in molecular systems

The remarkable advances in nanoscience and nanotechnology over the last two decades allow one to manipulate individuals atoms, molecules and nanostructures, make it possible to build devices with only a few nanometers, and enhance the nano-bio fusion in tackling biological and medical problems. It complies with the ever-increasing need for device miniaturization, from magnetic storage devices, electronic building blocks for computers, to chemical and biological sensors. Despite the continuing efforts based on conventional methods, they are likely to reach the fundamental limit of miniaturization in the next decade, when feature lengths shrink below 100 nm. On the one hand, quantum mechanical efforts of the underlying material structure dominate device characteristics. On the other hand, one faces the technical difficulty in fabricating uniform devices. This has posed a great challenge for both the scientific and the technical communities. The proposal of using a single or a few organic molecules in electronic devices has not only opened an alternative way of miniaturization in electronics, but also brought up brand-new concepts and physical working mechanisms in electronic devices. This thesis work stands as one of the efforts in understanding and building of electronic functional units at the molecular and atomic levels. We have explored the possibility of having molecules working in a wide spectrum of electronic devices, ranging from molecular wires, spin valves/switches, diodes, transistors, and sensors. More specifically, we have observed significant magnetoresistive effect in a spin-valve structure where the non-magnetic spacer sandwiched between two magnetic conducting materials is replaced by a self-assembled monolayer of organic molecules or a single molecule (like a carbon fullerene). The diode behavior in donor(D)-bridge(B)-acceptor(A) type of single molecules is then discussed and a unimolecular transistor is designed. Lastly, we have proposed and primarily tested the idea of using functionalized electrodes for rapid nanopore DNA sequencing. In these studies, the fundamental roles of molecules and molecule-electrode interfaces on quantum electron transport have been investigated based on first-principles calculations of the electronic structure. Both the intrinsic properties of molecules themselves and the detailed interfacial features are found to play critical roles in electron transport at the molecular scale. The flexibility and tailorability of the properties of molecules have opened great opportunity in a purpose-driven design of electronic devices from the bottom up. The results that we gained from this work have helped in understanding the underlying physics, developing the fundamental mechanism and providing guidance for future experimental efforts.

Evaluating retraining rules for semi-supervised learning in neural network based cursive word recognition

Training a system to recognize handwritten words is a task that requires a large amount of data with their correct transcription. However, the creation of such a training set, including the generation of the ground truth, is tedious and costly. One way of reducing the high cost of labeled training data acquisition is to exploit unlabeled data, which can be gathered easily. Making use of both labeled and unlabeled data is known as semi-supervised learning. One of the most general versions of semi-supervised learning is self-training, where a recognizer iteratively retrains itself on its own output on new, unlabeled data. In this paper we propose to apply semi-supervised learning, and in particular self-training, to the problem of cursive, handwritten word recognition. The special focus of the paper is on retraining rules that define what data are actually being used in the retraining phase. In a series of experiments it is shown that the performance of a neural network based recognizer can be significantly improved through the use of unlabeled data and self-training if appropriate retraining rules are applied.

Dynamic computer simulation of electrophoretic enantiomer migration order and separation in presence of a neutral cyclodextrin

One-dimensional dynamic computer simulation was employed to investigate the separation and migration order change of ketoconazole enantiomers at low pH in presence of increasing amounts of (2-hydroxypropyl)-β-cyclodextrin (OHP-β-CD). The 1:1 interaction of ketoconazole with the neutral cyclodextrin was simulated under real experimental conditions and by varying input parameters for complex mobilities and complexation constants. Simulation results obtained with experimentally determined apparent ionic mobilities, complex mobilities, and complexation constants were found to compare well with the calculated separation selectivity and experimental data. Simulation data revealed that the migration order of the ketoconazole enantiomers at low (OHP-β-CD) concentrations (i.e. below migration order inversion) is essentially determined by the difference in complexation constants and at high (OHP-β-CD) concentrations (i.e. above migration order inversion) by the difference in complex mobilities. Furthermore, simulations with complex mobilities set to zero provided data that mimic migration order and separation with the chiral selector being immobilized. For the studied CEC configuration, no migration order inversion is predicted and separations are shown to be quicker and electrophoretic transport reduced in comparison to migration in free solution. The presented data illustrate that dynamic computer simulation is a valuable tool to study electrokinetic migration and separations of enantiomers in presence of a complexing agent.

The Effects of a Physical Activity Intervention on the way Elementary School Girls Play

The rates of childhood and adolescent obesity in the United States have been increasing steadily. American youth continue to eat more (increase energy intake) and reduce physical activity (decrease energy expenditure) resulting in increased body weight and body fatness. One way to help reduce body weight in children is to increase physical activity. The purpose of this study was to determine if an age appropriate before-school physical activity intervention would be successful in increasing energy expenditure, intensity of activity, and behavioral approaches in overweight girls. The subjects were recruited from Parker Memorial School in Tolland, Connecticut, and two testing periods occurred over an eight week period. Video recordings of each physical activity session were analyzed to determine energy expenditure, exercise intensity, and behaviors during exercise. Data was evaluated for normal distribution, and paired t-tests were used to determine statistical significance. This study showed that the age appropriate before school physical activity intervention was able to increase energy expenditure and exercise intensity and have a positive effect on behavioral approaches in overweight girls.

WiMAX,Technology and Market.

Wireless communication is the transfer of information from one place to another without using wires. From the earliest times, humans have felt the need to develop techniques of remote communication. From this need arose the smoke signals, communication by sun reflection in mirrors and so on. But today the telecommunications electronic devices such as telephone, television, radio or computer. Radio and television are used for one-way communication. Telephone and computer are used for two-way communication. In wireless networks there is almost unlimited mobility, we can access the network almost anywhere or anytime. In wired networks we have the restriction of using the services in fixed area services. The demand of the wireless is increasing very fast; everybody wants broadband services anywhere anytime. WiMAX (Worldwide Interoperability for Microwave Access) is a broadband wireless technology based on IEEE 802.16-2004 and IEEE 802.16e-2005 that appears to solve this demand. WIMAX is a system that allows wireless data transmission in areas of up to 48 km of radius. It is designed as a wireless alternative to ADSL and a way to connect nodes in wireless metropolitan areas network. Unlike wireless systems that are limited in most cases, about 100 meter, providing greater coverage and more bandwidth. WIMAX promises to achieve high data transmission rates over large areas with a great amount of users. This alternative to the networks of broadband access common as DSL o Wi-Fi, can give broadband access to places quickly to rural areas and developing areas around the world. This paper is a study of WIMAX technology and market situation. First, the paper is responsible for explaining the technical aspects of WIMAX. For this gives an overview of WIMAX standards, physical layer, MAC layer and WiMAX, Technology and Market Beijing University of Post and Telecommunications 2 WIMAX network architecture. Second, the paper address the issue of market in which provides an overview of development and deployment of WIMAX to end the future development trend of WIMAX is addressed. RESUMEN: Por comunicaciones inalámbricas se entiende la transferencia de información desde un lugar a otro sin la necesidad de un soporte físico como es por ejemplo el cable. Por lo que remontándose a los principios de la existencia del ser humano, nos damos cuenta de que el ser humano siempre ha sentido la necesidad de desarrollar técnicas para lograr comunicarse a distancia con sus semejantes. De dicha necesidad, surgieron técnicas tan ancestrales como puede ser la comunicación mediante señales de humo o por reflexión de los rayos solares en espejos entre otras. La curiosidad del ser humano y la necesidad de comunicarse a distancia fue la que llevó a Alexander Graham Bell a inventar el teléfono en 1876. La aparición de un dispositivo que permitía comunicarse a distancia permitiendo escuchar la voz de aquella persona con la que se quería hablar, supuso una revolución no solo en el panorama tecnológico, si no también en el panorama social. Pues a parte de permitir comunicaciones a larga distancia, solventó el problema de la comunicación en “tiempo real”. A raíz de este invento, la tecnología en materia de comunicación ha ido avanzando significativamente, más concretamente en lo referido a las comunicaciones inalámbricas. En 1973 se realizó la primera llamada desde un terminal móvil aunque no fue hasta 1983 cuando se empezó a comercializar dicho terminal, lo que supuso un cambio de hábitos y costumbres para la sociedad. Desde la aparición del primer móvil el crecimiento del mercado ha sido exponencial, lo que ha repercutido en una demanda impensable de nuevas aplicaciones integradas en dichos dispositivos móviles que satisfagan las necesidades que día a día autogenera la sociedad. Tras conseguir realizar llamadas a larga distancia de forma inalámbrica, el siguiente paso fue la creación de los SMS (Short Message System) lo que supuso una nueva revolución además de abaratar costes al usuario a la hora de comunicarse. Pero el gran reto para la industria de las comunicaciones móviles surgió con la aparición de internet. Todo el mundo sentía la necesidad de poder conectarse a esa gran base de datos que es internet en cualquier parte y en cualquier momento. Las primeras conexiones a internet desde dispositivos móviles se realizaron a través de la tecnología WAP (Wireless Application Protocol) hasta la aparición de la tecnología GPRS que permitía la conexión mediante protocolo TCP/IP. A partir de estas conexiones han surgido otras tecnologías, como EDGE, HSDPA, etc., que permitían y permiten la conexión a internet desde dispositivos móviles. Hoy en día la demanda de servicios de red inalámbrica crece de forma rápida y exponencial, todo el mundo quiere servicios de banda ancha en cualquier lugar y en cualquier momento. En este documento se analiza la tecnología WiMAX ( Worldwide Interoperability for Microwave Access) que es una tecnología de banda ancha basada en el estándar IEEE 802.16 creada para brindar servicios a la demanda emergente en la banda ancha desde un punto de vista tecnológico, donde se da una visión de la parte técnica de la tecnología; y desde el punto de vista del mercado, donde se analiza el despliegue y desarrollo de la tecnología desde el punto de vista de negocio. WiMAX es una tecnología que permite la transmisión inalámbrica de datos en áreas de hasta 48Km de radio y que está diseñada como alternativa inalámbrica para ADSL y para conectar nodos de red inalámbrica en áreas metropolitanas. A diferencia de los sistemas inalámbricos existentes que están limitados en su mayoría a unos cientos de metros, WiMAX ofrece una mayor cobertura y un mayor ancho de banda que permita dar soporte a nuevas aplicaciones, además de alcanzar altas tasas de transmisión de datos en grandes áreas con una gran cantidad de usuarios. Se trata de una alternativa a las redes de acceso de banda ancha como DSL o Wi-Fi, que puede dar acceso de banda ancha a lugares tales como zonas rurales o zonas en vías de desarrollo por todo el mundo con rapidez. Existen dos tecnologías de WiMAX, WiMAX fijo (basado en el estándar IEEE 802.16d-2004) y WiMAX móvil (basado en el estándar IEEE 802.16e-2005). La tecnología fija está diseñada para comunicaciones punto a multipunto, mientras que la fija lo está para comunicaciones multipunto a multipunto. WiMAX móvil se basa en la tecnología OFDM que ofrece ventajas en términos de latencia, eficiencia en el uso del espectro y soporte avanzado para antenas. La modulación OFDM es muy robusta frente al multitrayecto, que es muy habitual en los canales de radiodifusión, frente al desvanecimiento debido a las condiciones meteorológicas y frente a las interferencias de RF. Una vez creada la tecnología WiMAX, poseedora de las características idóneas para solventar la demanda del mercado, ha de darse el siguiente paso, hay que convencer a la industria de las telecomunicaciones de que dicha tecnología realmente es la solución para que apoyen su implantación en el mercado de la banda ancha para las redes inalámbricas. Es aquí donde entra en juego el estudio del mercado que se realiza en este documento. WiMAX se enfrenta a un mercado exigente en el que a parte de tener que dar soporte a la demanda técnica, ha de ofrecer una rentabilidad económica a la industria de las comunicaciones móviles y más concretamente a las operadoras móviles que son quienes dentro del sector de las telecomunicaciones finalmente han de confiar en la tecnología para dar soporte a sus usuarios ya que estos al fin y al cabo lo único que quieren es que su dispositivo móvil satisfaga sus necesidades independientemente de la tecnología que utilicen para tener acceso a la red inalámbrica de banda ancha. Quizás el mayor problema al que se ha enfrentado WiMAX haya sido la situación económica en la que se encuentra el mundo. WiMAX a comenzado su andadura en uno de los peores momentos, pero aun así se presenta como una tecnología capaz de ayudar al mundo a salir hacia delante en estos tiempos tan duros. Finalmente se analiza uno de los debates existentes hoy en día en el sector de las comunicaciones móviles, WiMAX vs. LTE. Como se puede observar en el documento realmente una tecnología no saldrá victoriosa frente a la otra, si no que ambas tecnologías podrán coexistir y trabajar de forma conjunta.

Procesos de dualización en la sociedad de la información: algunas polémicas públicas de índole tecnológica

La tecnología ha cambiado el mundo, pero las consecuencias de estos cambios en la sociedad no siempre se han pronosticado bien. Las Tecnologías de la Información transformaron el método de producción industrial. La nueva industria produce ideas y conceptos, no objetos. Este cambio ha dado como resultado una sociedad dualizada, ha desaparecido gran parte de la clase media y han aumentado las diferencias entre la clase alta y la baja. Las exigencias educativas de los nuevos puestos de trabajo innovadores son superiores a los de la industria tradicional, pero inferiores en los puestos de trabajo de producción. Además, el número de puestos de trabajo disponibles de este tipo es menor que en la industria tradicional, se necesita menos mano de obra, los procesos se pueden automatizar, las tareas mecánicas se aprenden en poco tiempo y son trabajos temporales, cuyo número dependerá de la demanda global. Para que el proceso de innovación funcione, las empresas se reúnen en las zonas financieras de grandes ciudades, como Nueva York o Londres, que fueron las primeras con acceso a las redes de telecomunicación. De esta manera se producen sinergias que contribuyen a mejorar el proceso innovador global. Estas ideas y conceptos que cambian el mundo necesitan de este entorno de producción, que no puede ser replicado, y son tan importantes que su acceso está restringido para la mayor parte del mundo por distintos mecanismos de control. El despliegue de las redes de telecomunicaciones inalámbricas ha sido enorme en los últimos años. El cliente busca llamar desde cualquier lugar y llevar un acceso a Internet en teléfono móvil. Para conseguirlo, las operadoras de telefonía móvil necesitan poner antenas de telefonía móvil en las ciudades, pero la instalación cerca de edificios no está siendo fácil. Pocos quieren tener una antena cerca por los problemas de salud de las personas que padecen los que ya viven o trabajan cerca de una. Los efectos del electromagnetismo en los seres humanos no están claros y provocan desconfianza hacia las antenas. La digitalización de los contenidos, que ha sido necesaria para transmitir contenido en Internet, permite que cualquier persona con un ordenador y una conexión a Internet pueda publicar un disco, una película o un libro. Pero esa persona también puede copiar los originales y enviarlos a cualquier lugar del mundo sin el permiso del autor. Con el fin de controlar la copia no autorizada, los derechos de autor se están usando para cambiar leyes e incluir sistemas de censura en Internet. Estos sistemas permiten a los autores eliminar el contenido ilegal, pero también pueden ser usados para censurar cualquier tipo de información. El control de la información es poder y usarlo de una manera o de otra afecta a todo el planeta. El problema no es la tecnología, que es solo una herramienta, es la forma que tienen los gobiernos y las grandes empresas de usarlo. Technology has changed the world, but the consequences of these changes in society have not always been well predicted. The Information Technology transformed the industrial production method. The new industry produces ideas and concepts, not objects. This change has resulted in a society dualized, most of the middle class has disappeared and the differences between high and low class have increased. The educational requirements of new innovative jobs are higher than the ones of the traditional industry, but lower in production jobs. Moreover, the number of available jobs of this type is lower than in the traditional industry, it takes less manpower, processes can be automated, mechanical tasks are learned in a short time and jobs are temporary, whose number depends on global demand. For the innovation process works, companies meet in the business districts of large cities, like New York or London, which were the first with access to telecommunications networks. This will produce synergies that improve the overall innovation process. These ideas and concepts that change the world need this production environment, which cannot be replicated, and are so important that their access is restricted to most of the world by different control mechanisms. The deploy of wireless telecommunications networks has been enormous in recent years. The client seeks to call from anywhere and to bring Internet access in his mobile phone. To achieve this, mobile operators need to put cell towers in cities, but the installation near buildings is not being easy. Just a few want to have an antenna closely because of the health problems suffered by people who already live or work near one. The effects of electromagnetism in humans are unclear and cause distrust of antennas. The digitization of content, which has been necessary to transmit Internet content, allows anyone with a computer and an Internet connection to be able to publish an album, a movie or a book. But that person can also copy the originals and send them anywhere in the world without the author's permission. In order to control the unauthorized copying, copyright is being used to change laws and include Internet censorship systems. These systems allow authors to eliminate illegal content, but may also be used to censor any information. The control of knowledge is power and using it in one way or another affects the whole planet. The problem is not technology, which is just a tool, but the way that governments and large corporations use it.
