Microstrip patch antennas are probably the most widely used type of antennas today due to their advantages such as light weight, low volume, low cost, compatibility with integrated circuits and easy to install on the rigid surface. Furthermore, they can be easily designed to operate in dual-band, multi-band application, dual or circular polarization. They are important in many commercial applications. The microstrip patch has few drawbacks such as narrow bandwidth, low efficiency, low gain. A recently introduced method that can overcome such drawbacks is by embedding the ground with a defective ground structure (DGS). The aim is to design the Microstrip rectangular patch antenna that operates at the frequencies 2.45 GHz and 5GHz.The transmission line model is used for the analysis. In designing the Microstrip patch antenna, selection of the patch width and length are the major parameters along with the feed line and Microstrip patch antenna is realized according to the requirements of the design.

Cancer is a disease of autonomous and uncontrolled cell proliferation which deregulates cell division and sometimes metastasis.It is an effort to treat squamous cell carcinoma by using benefit of oncolytic property of apoptin.Which is a protein produced by chicken Infectious anemia virous in poultry.CAI is one of the smallest avian viruses it is 23-25 nm in size,icosahedral in shape and non enveloped,having a 2.3 Kb,and single-standered DNA genome.The VP3 protein "Apoptin" synthesized by CIA Virus has a unique property when exposed to human tissue cultures.Previous research has concludeded that transformed (cancerous)cells infected with a vector containing the gene for expressing VP3 (Apoptin)under go synthesis.Apoptin also causes apoptosis in SV40-transformed fibroblasts or UV-irradiated cells from individual with hereditary cancer-prone syndromes.Where as,when the gene for apoptin synthesis was expressed in infected normal cells,cell death was not observed.

Wireless Sensor Networks (WSNs) have the ability to sense their surrounding environmental conditions using battery operated sensor nodes. To ensure the nodes to work in a low power consumption mode for the long life of network, it is important that these networks are configured properly and are optimized for their usage scenario. Moreover, configuring the network should not be a difficult task since network administrator may not be familiar with WSNs specific platform. So, configuration techniques need to be studied for optimized performance of WSNs. In this book, we study two approaches by which WSNs can be configured easily - Macroprogramming and Query driven configuration of MAC protocols. The book presents simulation results which should be helpul while configuring WSNs.
