Addressing mandates and legislation introduced since the first edition, this new edition of an essential text identifies the role the private sector plays in securing our homeland and offers strategies to aid in the fight against national and international threats. It includes updates to the NIPP (National Infrastructure Protection Plan), new case studies of both proper security policies and procedures in practice versus costly security breaches, a toolkit for improving a company‘s security posture, and new measures to assess and address vulnerabilities and threats.
Describes the systems commonly employed for producing fiber Braggs gratings (FBGs) in silica fibers that can be used for the production of POFBGs Explores different laser sources for the inscription of POFBGs Explores the capability of using this technology at the visible and infrared region, in different fiber types (e.g., step-index, microstructured, unclad, highly birefringent) and in fibers composed of different polymer materials such as PMMA, doped PMMA, PS and ZEONEX Reports the fabrication of different types of POF gratings, such as uniform, phase-shifted, tilted, chirped, and long period gratings Shows the opportunities of POFBGs for a variety of sensing applications
Photochemistry of Heterocycles is a comprehensive review of the topic, including photooxidation, photoreduction and photoaddition reactions as well as industrial aspects of heterocyclic photochemistry. Many materials used for the manufacturing of OLEDs and other electrooptical switches contain heterocycles, and the use of small molecules or polymers containing heterocyclic substances are being studied as new photovoltaic materials. This reference is ideal for synthetic organic chemists, specifically researchers working in organic photochemistry, as well as medicinal chemists and material scientists. Heterocyclic compounds are widely used in the modern world, and most of the drugs currently in use have heterocyclic nuclei among their constituents. These compounds are subject to a photochemical degradation processes which must be known and prevented. - Presents an authoritative and comprehensive review of the photochemistry of heterocycles - Covers the full spectrum of photochemical reactivity, including photoreduction and photoaddition reactions of heterocyclic compounds - Includes industrial aspects of heterocyclic photochemistry and materials used to manufacture OLEDs and other electrooptical switches
Despite recent advances, therapeutic efforts have not been successful establishing a definitive strategy of treatment for brain gliomas, because of the presence of the blood-brain barrier. Innovative Brain Tumor Therapy presents a synopsis of the studies on nanoparticles as ideal devices for brain tumor treatment. Their nanometric size, electrostatic charge, and lipophilic characteristics allow them to penetrate into the brain tissue freely. Promising in-vitro results have been reported, but remain to be validated in humans. This title focuses on the blood-brain barrier pathophysiology in brain tumors, and the possibilities of overcoming this with nanoparticle-based systems. Relevant patents of nanoparticles used as drug delivery carriers are also reported, as well as future scenarios in nanoparticles and stem cells.
