Countless times I have wondered how we can be successful in every aspect in life, why some of us are and some aren’t. The truth is those who are; know the essentialness of self-image upgrade and update, as well as, that the power behind change of mind is formula for change of life. Bursting the boundaries of our mental limitations and emancipating ourselves of constricting conservative thoughts paves out the expansion of what we are destined to achieve.
Stop, Think, only for a moment, now, write a figure that you want to accumulate in precisely 12 months from now, no limits, no restrictions.
The exact amount will tell you how much value you attribute to yourself in one year, surprising? No? Ask yourself, why did you put that particular figure? Why not one pound, one dollar, or one penny more? (Remove every external factor that your mind is bound by) By this simple exercise which takes less than a few seconds we can astronomically shift the poles of our self-image and accomplish anything. There are no limits in what you can achieve…

New nanomaterials are leading to a range of emerging dental treatments that utilize more biomimetic materials that more closely duplicate natural tooth structure (or bone, in the case of implants). The use of nanostructures that will work in harmony with the body’s own regenerative processes (eg, to restore tooth structure or alveolar bone) are moving into clinical practice. This book brings together an international team of experts from the fields of nanomaterials, biomedical engineering and dentistry, to cover the new materials and techniques with potential for use intra-orally or extra-orally for the restoration, fixation, replacement, or regeneration of hard and soft tissues in and about the oral cavity and craniofacial region. New dental nanotechnologies include the use of advanced inorganic and organic materials, smart and biomimetic materials, tissue engineering and drug delivery strategies. This book prepared by an interdisciplinary and international group of bio-nanomaterial scientists and dental/oral biomedical researchers. It is a comprehensive professional reference for the subject covering materials fabrication and use of materials for all major diagnostic and therapeutic dental applications – repair, restoration, regeneration, implants and prevention. This book focuses in depth on the materials manufacturing processes involved with emphasis on pre-clinical and clinical applications, use and biocompatibility.

Biometrics is concerned with measurement and analysis of a universal, unique and measurable physiological or behavioural characteristic. Biometric data is taken from individuals, extracting feature sets from the data and comparing it with the enrolment set in a database. Existing analyses techniques using wearable sensors are applied to gait analyses in children for biometric gait recognition. The performance degradation for children walking compared to adult walking is approximately 100%. A 6.21% Equal Error Rate (EER) for adult gait recognition was reached compared to 12.69% for children. Carrying an object showed that the performance actually improved compared to normal walking. However, faster walking was unstable resulting in a higher Equal Error Rate (EER). Age and gender differences showed significant variations in EER values. A coupled approach of statistical time-domain and frequency domain methods was employed to match biometric gait signals. Using root mean squared, crest-factor and kurtosis obtained similar matches in gait signals of children for the ages of 5-16 than for the traditional methods.
Nanocarrier Systems for Drug Delivery for the Treatment of Asthma: Liposomes as Model Carrier Systems

Publisher: Lambert Academic Publishers
This book presents work on nanocarrier systems for pulmonary drug delivery for use in the treatment of asthma. Using sucrose as a carrier, liposomes were generated or dispersed in situ from proliposomes within the medical nebulisers investigated. The Pari (air-jet) and the Omron (vibrating-mesh) nebulisers produced large mass and lipid outputs with a large lipid fraction deposited in the lower stage of a two-stage impinger. The Liberty (Ultrasonic) nebuliser failed to deliver more than 6% of the lipid employed.Multilamellar liposomes were generated from ethanol-based proliposomes. The resultant vesicles entrapped 62% of the available salbutamol sulphate compared to only 1.23% entrapped by liposomes made by the thin film method. Aeroneb Pro or Aeroneb Go vibrating-mesh nebulisers generated aerosol droplets of larger volume median diameter and narrower size distribution than the Pari (air-jet) nebuliser. Unlike the vibrating-mesh nebulisers, the performance of the jet nebuliser was independent of formulation. A nebuliser-dependent significant loss of the originally entrapped drug was demonstrated. A customised large mesh Aeroneb Pro reduced the drug losses during nebulisation.

Carbon is an essential constituent element of all living organisms. A unique feature of carbon is the variety of forms that it can assume when two or more atoms bond. Carbon has thus attracted, and continues to attract, considerable R&D interest from researchers all over the world. The use of carbon in nanotechnology is a very promising area of research, and considerable government funding is being invested in carbon nanotechnology research.
Even after many years of study, an aura of mystery continues to surround the question of how many crystallographic forms/allotropes of carbon exist. The known forms of carbon are: graphene, graphite, diamond, nanotubes, fullerenes (C60, C36….) and nanodiamondoids. Each of these forms of carbon is characterized by different numbers of hybrid orbitals (sp2, sp3, sp).
This work comprises ten comprehensive chapters, on carbon-based materials, written by experts in the field. The chapters contain up-to-date fundamental and practical information concerning carbon-based materials. They include work on diamondoid hydrocarbons, carbon nanotubes, nanocrystalline/microcrystalline/ultra-nanocrystalline diamond and carbon nanostructured materials, thus providing an uniquely valuable introduction to the subjecy.

Nanocomposite materials are formed by mixing two or more dissimilar materials at the nanoscale in order to control and develop new and improved structures and properties. The properties of nanocomposites depend not only upon the individual components used but also upon the morphology and the interfacial characteristics. Nanocomposite coatings and materials are among the most exciting and fastest-growing areas of research; with new materials being continually developed which often exhibit novel properties that are absent in the constituent materials. Nanocomposite materials and coatings therefore offer enormous potential for new applications including: aerospace, automotive, electronics, biomedical implants, non-linear optics, mechanically reinforced lightweight materials, sensors, nano-wires, batteries, bioceramics, energy conversion and many others. This exciting new book comprises 9 chapters; each written in an easily understandable style by international experts and in a format suitable for students (undergraduate or post-graduate), technologists and experts seeking to expand their knowledge in the area of nanocomposite materials and coatings. Although an elementary knowledge of materials is assumed throughout, there is a comprehensive introduction to each chapter which covers the most important references, details of the experimental methods and techniques used, and a description of the latest research work. Four comprehensive chapters cover the design, synthesis and applications of nanocomposite coatings. Past developments in nanocomposites were hindered by a lack of available characterisation techniques for probing materials at the nanoscale. A complete chapter is therefore dedicated to the latest characterisation techniques available for investigating nanocomposite coatings and nanocomposite materials. Organic/inorganic nanocomposite materials have a vast potential for fulfilling many new applications and, by engineering the polymers-host interactions, nanocomposites having a broad range of properties can be produced. The synthesis and the applications of hybrid organic-inorganic nanostructured materials are described in a particularly comprehensive chapter. Novel routes are being developed in order to synthesise three-dimensional nanocomposites. Hence, three chapters are devoted to nanowires, reinforced nanocomposites and hierarchical nanocomposites.

Biomedical engineering involves the application of the principles and techniques of engineering to the enhancement of medical science as applied to humans or animals. It involves an interdisciplinary approach which combines the materials, mechanics, design, modelling and problem-solving skills employed in engineering with medical and biological sciences so as to improve the health, lifestyle and quality-of-life of individuals. Biomedical engineering is a relatively new field, and involves a whole spectrum of disciplines covering: bioinformatics, medical imaging, image processing, physiological signal processing, biomechanics, biomaterials and bioengineering, systems analysis, 3-D modelling, etc. Combining these disciplines, systematically and synergistically yields total benefits which are much greater than the sum of the individual components. Prime examples of the successful application of biomedical engineering include the development and manufacture of biocompatible prostheses, medical devices, diagnostic devices and imaging equipment and pharmaceutical drugs.
The purpose of this book is to present the latest research and development carried out in the areas of biomedical engineering, biomaterials and nanomaterials science and to highlight the applications of such systems. Particular emphasis is given to the convergence of nano-scale effects, as related to the delivery of enhanced biofunctionality. The contents describe a number of materials/engineering approaches that are currently being explored in order to create systems that can impart clinical benefits. They reflect many of the significant challenges to producing medical implants and therapies that are capable of achieving the regeneration of viable tissues and organs for implantation. It is intended that this volume should serve as a key reference for those who wish to contribute to the global endeavour towards improving the clinical outcomes for patients of today and tomorrow.
