CHAPTER-1 INTRODUCTION TO NEAR FIELD COMMUNICATION Near Field Communication (NFC) is a technology for contactless short-range communication. Based on the Radio Frequency Identification (RFID)‚ it uses magnetic field induction to enable communication between electronic devices. The number of short-range applications for NFC technology is growing continuously‚ appearing in all areas of life. Especially the use in conjunction with mobile phones offers great opportunities.

carbon dioxide is used to synthesis carbohydrates(P.121‚ The Living World‚ 7th Ed). Photosystem II is the first protein complex in the light-dependent reactions. The portion of the protein that contains the pigment molecules is called the antenna complex. The antenna complex captures energy from photons and transfers into the reaction center chlorophyll‚ which is the P680. Once excited the P680 gives up an electron to the electron transport chain. The empty electron orbital formed is filled with an

The inbuilt embedded chip represents the 12 digit card number. RFID reader is the circuit which generates 125KHZ magnetic signal. This magnetic signal is transmitted by the loop antenna connected along with this circuit which is used to read the RFID card number. In this project RFID card is used as security access card.

During experiment one‚ one connected the antenna to the ground when one supposed to connect the antenna to the fahnstock clips. Next time‚ if one should build a crystal radio one should buy a single wire‚ wooden ladder‚ and read the directions carefully. I would like to know any available replacement for the germanium diode

morphological features are readily observed. Like most other insects‚ the grasshopper (or other Orthopteroid) consists of three general body regions: the head‚ thorax and abdomen. For morphological studies‚ antennae were detached from the specimen. Then‚ the antenna was mounted in a glass slide. The prepared slides were then examined under magnoscope for studying the anatomical features. The grasshopper was illustrated and each part was properly identified. The most obvious and distinctive features of grasshoppers
