Drug- and gene delivery to the brain is highly restricted by the vascular barriers of the brain, denoted by the blood-brain barrier (BBB) and the blood-cerebrospinal fluid (CSF) barriers. Among these barriers, BBB is the main limiting factor. It is composed by the brain capillary endothelial cells (BCECs). The BCECs barrier function is supported by astrocytes, pericytes and neurons to form the blood-brain barrier. BCECs are very tightly connected to each other by tight junctions. Apart from the essential substrates needed to nourish the brain, small and/or lipophilic molecules are free to diffuse into the brain. However most pharmacologically active drugs and gene fragments are too large to enter the brain. Various kinds of drug-carriers have been constructed for delivery of large substances to the brain. Such drug-carriers have to be able to successfully carry their cargo through the BCECs and into the brain. For testing the ability of drug-carriers to deliver their cargo into the brain, investigators have constructed different in vitro BBB models, consisting of BCECs that express the main characteristics of the BBB in vivo.In the first part of the thesis the ability of two drug-carriers, pullulanspermine and SPIOs, to mediate transfection of BCECs or transcellular transport through BCECs in vitro was studied.

The work presented in this PhD thesis is the result of research carried out at the Center for Sensory-Motor interaction (SMI) at Aalborg University (Denmark) in the period from September 2009 to March 2013. The research was supported by the Danish Research Council for Technology and Production (FTP). During this project five months, between April and August 2011, were spent at Duke University, Durham, NC, USA in collaboration with Dr. Warren M. Grill. This thesis investigates the basic methodology behind the human nociceptive withdrawal reflex (NWR). The aims of this thesis were to investigate this methodology as a potential way of reducing the variability of NWR assessment and, if possible try, to discover methods which could help to reduce this variability. In order to fulfill these aims electrophysiological experiments, advanced mathematical modeling and anatomical studies were applied to investigate the elicitation and recording of the NWR. This thesis contains four chapters. The Introduction presents the reader to the background and motivation for this project and gives a general overview of the PhD thesis.The Methods chapter introduces the used methods and elaborates the background for choosing them. The Results chapter presents and discusses the main findings in this thesis; in addition, all these findings are further elaborated in the original papers. The Conclusions chapter sums up the main findings and the impact on the state of the art, and finally looks at the perspectives towards future studies. The thesis is based on three original papers that all are either published in, or submitted to, peer-reviewed journals. In addition one submitted peer- reviewed paper and several conference abstracts were based on the research conducted in this project.

The success of a neural electrode is often measured by its performance in the selective stimulation of or recording from individual fascicles within a peripheral nerve without damaging the nerve. Neural prostheses are limited by the availability of peripheral neural electrodes that can be used to record the user's intention or to provide sensory feedback through functional electrical stimulation for an extended duration. Improvement in future neural prostheses may be achieved through the availability of multichannel, bidirectional neural interfaces, such as the transverse intrafascicular multichannel electrode (TIME). The aim of this thesis was to investigate the biofunctionality, biostability, and biosafety of the TIME in an animal model that bears a close neuroanatomical resemblance to the human. To this end, four research questions were formulated: 1) Is the pig model neuro-anatomically suitable for the simulation of the actions and reactions of a neural electrode in a large human-sized peripheral nerve? This question was addressed in study 1 in which a comparative morphology study was performed on the median and ulnar nerves of Danish landrace pigs and Gottingen mini-pigs.Nerve specimens were selected at different levels for analysis. The number of fascicles in each nerve was counted, and the fascicle diameters were measured. 2) How selective is the TIME compared to other intrafascicular electrodes, such as the thin-film longitudinal intrafascicular electrode (tfLIFE)? Study 2 was performed to address this question. A comparative stimulation selectivity study was performed in Danish Landrace pigs with the TIME and tfLIFE. Electrodes were implanted in the median nerve, and sequential electric stimulation was applied to individual contacts. The compound muscle action potentials of seven forelimb muscles were recorded to quantify muscle recruitment. 3) Is the TIME biostable and biofunctional for long-term implantation? This question was addressed in study 3 in which the chronic stimulation selectivity of the TIME was evaluated on Gottingen mini-pigs. 4) Does the TIME fulfil the criteria of biocompatibility and chronic stability? Study 4 was conducted to address this question. Immunohistological analysis was conducted on nerve specimens from chronic experiment pigs that had been implanted with TIMEs in study 3.

The high pressure of the giraffe cardiovascular system undoubtedly causes serious challenges to both the heart and the systemic vasculature. Mechanisms must have evolved to protect the giraffe cardiovascular system from the adverse effects of a high MAP. The present thesis aims to unveil some of the protective mechanisms in the cardiovascular system in the giraffe and to gain knowledge of the evolutionary adaptations accompanying the highest known MAP of any mammals.

Paperback. Condizione: New. Features a collection of twenty-five interviews with practitioners who are testing the boundaries between the sciences, arts and humanities. Divided into three chapters: On Science, On Art, and On Society, these interviews illustrate to the reader how models of hybridity can nurture new forms of innovation across disciplines and sectors.Fostering innovation in this way is not a simple linear process, but, rather, a complex and multifarious one. It requires the networking of different resources and talents, the pooling of skills, the challenging of boundaries, and the exploration of risk. In facing many of our 21st century problems, new forms of convergence between disciplinary practices are now seen as a necessity, and point to an understanding of innovation that must include some form of hybridity if it is to prove effective.Models of hybrid innovation that can draw on diverse resources, and which can be implemented as a catalyst to trigger innovation, are becoming increasingly common in a variety of settings. A sense of urgency can be felt amongst many communities to reach outside the four walls of their institutions and establish - with all force - innovative platforms that can help tackle the complex challenges and opportunities they encounter. Amongst the many topics addressed in this book, for example, authors ask whether neuroscience can uncover the laws of aesthetics, whether citizen science will open scientific research to a larger community of stakeholders, whether corporate responsibility and grass-roots innovation can bring about a fairer society based on the sharing of opportunities and resources, and whether new approaches to tourism can help build inclusive and sustainable local economies.By providing platforms for knowledge exchange and co-creation across different disciplines, we will see the continued emergence of new forms of understanding and insight. Taken together, we are seeing the potential for hybrid models of innovation to usher in an era of more sustainable and responsible governance, economics, research, education and citizenship.Readers interested in innovation, and the processes that drive it, will find in each themed chapter unique insights from established, as well as upcoming, innovators. Offering examples from their own fields of expertise, we hope these interviews will act as a spark for future discussion, and inspire others to explore the exciting possibilities that cross-disciplinary collaboration can offer. We also hope that the Korean-Swiss context from which the book stems may serve as a model for nurturing cross-cultural exchange in this endeavour.

Paperback. Condizione: New. Over the period of last few decades, the 'C' language has become an icon for computer programmers. The field of computer science has undergone tremendous change, and the rate of obsolescence of concepts, programming platforms, tools and utilities is extremely high. However, in spite of such vast changes, the only thing that has retained its stability is the 'C' language. Even today, millions of students, hobbyists and professional programmers enjoy the sturdiness, reliability and user friendliness of the 'C' language. Today 'C' enjoys the undisputable recognition in the computing paradigm for diversified applications, from the basic programming, microcontrollers, and spreadsheets to system programming. In this book, most of the usual theoretical features have been skipped, for these have been widely published in previous books. Rather than introducing the underpinning theory, the authors approach has been "learning-through-doing", which is one that often appeals to programmers. Theory is followed by practical implementation, and in this way the book will cover programming aspects in a self-tutor manner providing an excellent overview, from basic to advance programming. Topics discussed include: . GCC interface. First time 'C' User. Decision and looping structures. Arrays and pointers. Functions, structures and union. Linear data structures.

Paperback. Condizione: New. This book introduces the Internet of Things (IoT), which is the convergence of connecting people, things, data and processes; it is transforming our life, business and everything in between. By 2025, experts forecast that up to 75 billion devices will be connected to the Internet with only one third of them being computers, smartphones, smartwatches, and tablets. The remaining two thirds will be other "devices" - sensors, terminals, household appliances, thermostats, televisions, automobiles, production machinery, urban infrastructure and many other "things", which traditionally have not been Internet enabled. This "Internet of Things" (IoT) represents a remarkable transformation of the way in which our world will soon interact. Much like the World Wide Web connected computers to networks, and the next evolution mobile devices connected people to the Internet and other people, IoT looks poised to interconnect devices, people, environments, virtual objects and machines in ways that only science fiction writers could have imagined.

Paperback. Condizione: New. Demand for wireless data exchange is perpetually increasing, leading to pressure on deployed wireless capacity. As systems enhance their spectral efficiency to attempt to address this, evermore complex processing techniques are being employed. Such techniques increase power consumption, leading to greater heat output from processers in network elements and increasing powered cooling. Moreover, the requirement for wideband linearity of radio frequency circuitry in state-of-the-art OFDM systems, twinned with high transmission power capability on the network side and the inefficiencies of components when operating at such limits, leads to greater inefficiency hence further heat power output and the need for greater cooling. All of these ingredients significantly affect the power consumption of communications equipment. Indeed, merely considering raw transmission power, the Shannon-Hartley theorem implies that necessary transmission power increases exponentially with required capacity. Such power consumption issues can be mitigated through cognitive radio (CR) techniques.The use of greater bandwidths through CR and in some cases the aggregation of bandwidths, as well as the opportunistic use of spectrum of more appropriate propagation characteristics or with better interference management, can reduce necessary transmission power for devices and systems. Moreover, CR techniques may achieve greater spatial/temporal awareness of connectivity options and their inherent power consumptions, as well as the power consumptions of chosen radio access characteristics. They might be able to use this awareness to dynamically switch to connections that better manage loads and interference, or might be able to minimize the power consumption of radio frequency circuitry through switching radio access technique given a required traffic load. At a simpler level, they may be able to appropriately select nearer connectivity options minimizing path loss/shadowing hence necessary transmission power, in consideration of experienced/predicted traffic loads and channel characteristics.Such capabilities are particularly relevant considering that, at least in terms of the transmission power to from-the-socket power consumption ratio, lower power equipment such as wireless LAN access points achieves far better efficiency than higher-power equipment such as macro-cell base stations. This manifestation is not only because of favorable path loss characteristics, but also because of the better efficiencies of the lower power components in such access points. CR might also assist in making other areas of life more environmentally friendly. The application of CR to intelligent transportation, for example, facilitating the sharing of information in a timely manner and with appropriate data rates among vehicles and between vehicles and roadside infrastructure through enhancing the capabilities of systems such as IEEE 802.11p, could lead to the better management of traffic signal.

In this sense, and increasingly, entrepreneurship courses have arisen in several universities and many of the courses in the management, administration and engineering areas already offer entrepreneurship curricular units. Throughout those programs, the teams develop key integrated competencies in innovation, entrepreneurship and technology that will ultimately enable the students to create and develop new technology-based businesses. The Business Plan Reference Manual for IT Businesses provides a reference manual for undergraduate and graduate students that intend to launch their start-up business in the IT field. It helps them to create and model the business plan of their business. Therefore, this manual is mainly aimed at instructors who want to offer a practical view of the process of modeling, designing and developing an IT start-up. Additionally, it can be individually used by entrepreneurs who wish to launch their start-up businesses in IT field. The structure of the book was defined taking into account different approaches to the construction of the business plan, which basically consider a disaggregation of some of these chapters in others smaller (e.g., marketing plan into products/services and market, financial plan into investment plan and economic-financial projections). We chose to aggregate these dimensions into a single chapter, which in our view facilitates the process of analyzing a business plan. It is also relevant to mention the inclusion of "Chapter V - Prototype description" which is innovative and intends to take into account the application of this business plan template to the information technology sector.
