Polybenzoxazines (PBz) belong to the family of new generation phenolic resins. They have emerged as addition-curable polymers. This feature obviates many of the shortcomings associated with conventional phenolic resins. They are endowed with excellent thermal, physical, and thermo-physical properties, and surpass the features of many conventional and state-of-the-art polymers. These unique materials offer extraordinary characteristics: near zero shrinkage, no release of volatiles during cure, high Tg, low flammability, and high UV and chemical stabilities. Given the breadth of molecular design flexibility, a wide variety of polybenzoxazines can be developed. PBz equipped with additional curing groups can generally enhance the overall thermal and mechanical properties. Blends with epoxy resins, cyanate esters, and bismaleimides offer other opportunities for fine-tuning properties. This chapter gives an account of the developments of PBz materials from their inception to the current level of application in engineering areas.

The steps in creating computers that are as fluent in human language as people has long been a goal for scientists and the general public. Human language communication both represents and challenges an intelligence, because while languages appear to follow some unseen rules of spelling and grammar. Systems that understand or use language, which we call ?Natural Language Processing? (NLP) systems, have been created by specifying algorithms for computers based on the observable regularities of language noted by experts.Use this book to learn the principles and methods of NLP to understand what it is, where it is useful, how to use it, and how it might be used people. The book includes the core topics of modern NLP, including an overview of the syntax and semantics of English, benchmark tasks for computational language modeling, and higher level tasks and applications that analyze or generate language, using both rule-based search and machine learning approaches. It takes the perspective of a computer scientist. The primary themes are abstraction, data, algorithms, applications and impacts. It also includes some history and trends that are important for understanding why things have been done in a certain way
Soil borne diseases which are caused to various plants include a wide variety of soil microbes like fungi and bacteria, among which Fusarium wilt is one such disease caused by Fusarium oxysporum cubense in banana plants. Wilt disease or the panama disease of plant is among the most destructive disease of banana in the tropics and even the control methods like field sanitation, soil treatments and crop rotations have not been a long term control for this disease. An alternative method of treating Fusarium oxysporum was adopted by using various banana parts mainly its peel, pulp sap and its latex of varieties such as Robusta (B1) Musa acuminate Colla (AAA), Etha (B2) Musa x paradisiaca (AAB), Poovan (B3) Musa x paradisiaca (AAB), Sundari (B4) Musa acuminate Colla (AA), Njalipoovan (B5) Musa acuminate Colla (AB), Palayamkodan (B6) Musa x paradisiaca (AAB), Kannan (B8) Musa acuminate Colla (AAA), Pachakadali (B9) Musa acuminate Colla (AAA). Nanoparticles are small particles with a dimension of 10-9 and 10-10. Green synthesis is a new method developed for the synthesis of nanoparticles which is small in size, large surface area and eco- friendly. Leaf extracts of these plants were used for synthesis of copper and zinc nanoparticles, as nanoparticles are powerful antimicrobial agents. The results shows that dry skin and fruit extracts of Palemkodan, Njalipoovan, Etha, Pachakhadali with solvents, propane, ethanol, methanol and acetone and the fresh extract latex and sap of Palemkodan and Poovan with solvents isoproponol, ethanol, methanol with 1/10 and 1/50 dilution are used for the synthesis of copper and zinc nanoparticles. Copper and zinc nanoparticle shows greater antifungal activity than copper sulphate and zinc sulphate, respectively and dry extract. The maximum zone of inhibition was at 50 and 100 µl for all the test plates. This indicates that the zone of inhibition increases with as the concentration of nanoparticles increased. An overall result showed that ethanol, methanol and isoropane could be used as a good solvents and skin of Njalipoovan and Etha could be used for controlling the Fusarium oxysporum cubense under invitro conditions.
