In internet of things (IoT) applications, wireless connectivity is a key factor, particularly those that need to be in transition, or where wired communication is not effective or practicable. For top-notch connectivity of the Narrowband IoT (NB-IoT) standard, the 900MHz frequency is generally used by most of the vendors. The radiation quality not only depends on the antenna geometry but on immediate surroundings. Additionally, the IoT product itself and the user of the product can strongly affect the resulting radiation pattern and other characteristics of the antenna. On the other hand, a suitable antenna should also have high efficiency and adequate bandwidth covering the desired frequency range. To take these effects into consideration, the whole IoT product must be included in the antenna simulations. Antenna Design for Narrowband IoT: Design, Analysis, and Applications provides the antenna design concept for narrowband internet of things applications, performs a detailed analysis of the antenna, and discusses the various antenna design concepts and structures. Covering a range of topics such as antenna design and antenna measurement systems, this book is ideal for industry professionals, research scholars, academicians, professors, and students.
In this study raw and branded milk samples were collected and were processed for the isolation and identification of Listeria monocytogenes. The experimental results shows that the presence of Listeria monocytogenes in raw as well as branded milk samples. This research indicated that the milk samples had significant effects on the bactericidal power of ozone against non-spore former, Gram positive bacilli Listeria monocytogenes. The ozonation treatment was to eliminate only the L. monocytogenes and there was no change in nature of milk that is color, temperature, pH and the nutritional values such as protein, carbohydrate, and calcium. So the ozonation treatment in milk is highly recommended in dairy industries. Further research is required to ascertain the precise mechanism of the application of ozonation for the milk samples.
