The endocrine system works with the nervous system to maintain homeostasis. The endocrine system secretes hormones in the human body‚ which are produced in endocrine glands and are released into the bloodstream to travel to the its specific target cell‚ tissue‚ or organ. Exocrine glands produce chemicals that are discharged into the surroundings. Hormones can either produce short-lived responses or long-term responses. An example of a short-lived response is when adrenaline (epinephrine)causes the

DCN VIVA QUESTIONS 1. What do you mean by data communication? Ans: It is the exchange of data between two devices via some form of transmission medium such as wire cable. The communicating system must be part of a communication system made up of a combination of hardware and software. The effectiveness of a data communication system depends on three fundamental characteristics: delivery‚ accuracy and timeliness. 2. What is simplex? Ans: It is the mode of communication between two devices in which

graphite is negligible at ambient conditions. Other specialized applications also exist or are being developed‚ including use as semiconductors: some blue diamonds are natural semiconductors‚ in contrast to most diamonds‚ which are excellent electrical insulators. The conductivity and blue color originate from boron impurity. Boron substitutes for carbon atoms in the diamond lattice‚ donating a hole into the valence band. Substantial conductivity is commonly observed in nominally undoped diamond grown by

CHAPTER 1 1.1 Introduction: After going through tedious working days isn’t it a wonderful thing if people can just relax on the sofa and control the temperature in the living room‚ just with single button the room temperature can be controlled automatically so when the room temperature is too cold the heater will operate to produce a regulated temperature and when the room temperature is too high the cooling system will operate to produce the desired temperature. 1.2 Objectives: There are
