A Journey to the Wonderland In this long holiday I had an opportunity to have a long distance journey-- visiting the Lake of the Heaven in Changbaishan Mountains. The Lake of Heaven was like a shy girl hiding behind a veil. Many people traveled a long distance to the place but sadly missed out this splendid view. After spending a peaceful night near the bottom of the mountain‚ we got up early the next morning and heading for the lake. Before we arrived the foot of the volcano‚ we were dismayed

transducer‚ impedance matching‚ tuning‚ equivalent circuit 1. Introduction Piezoelectric transducers are used for under water applications. As we know higher frequencies are more easily attenuated in water‚ so low frequency sound waves are used for under water mapping. Basically a transducer converts the electrical signal from power amplifier to acoustic signal‚ which propagates under water. A transducer is always operated at its resonance‚ where it has maximum amplitude of vibration

Alpha waves are regular‚ have medium frequency‚ and occur while resting. Beta waves are irregular‚ have a low amplitude‚ and occur while attentive. In stage one of the sleep cycle‚ we experience Theta waves‚ which have similar frequencies and regularity to Alpha waves. Stage two also involves Theta waves‚ but may also have short bursts of Alpha and Beta waves called sleep spindles‚ or Delta waves called k complexes. These are the two shallowest sleep

Temperature‚ Humidity‚ Precipitation‚ Air Pressure and Wind are the ingredients of Climate. -Methods of Heat Energy Transferring are Convection‚ Conduction‚ Radiation. Conduction involves heat transfer by physical contact between objects. Convection is the process of heat transmission by the actual motion of the heated body. Radiation is the process of heat (energy) transfer by electromagnetic waves‚ without using or necessity of transmitting medium. - Continental arctic air (cA) is typically described

The specific heat of an object depends what phase it is in. The more mass an object has‚ the more heat you will have to add for the temperature to change. The change in temperature also depends on how much you want the temperature to change by. Heat‚ which is represented as q‚ equals mass‚ which is represented as M times specific heat capacity‚ which is represented as C times delta T. The type of calorimeter that most people

rotisserie. Microwave ovens use micro waves (or radio waves) to create oscillating electric fields in the food‚ causing the positively charged hydrogen atoms in the water molecules to rotate and become excited. This excitation causes friction in all of the molecules in the food‚ and thus‚ heat‚ which is used to cook the food. This process differs from that of a conventional oven‚ which uses heat transfer via convection‚ rather than electromagnetic waves‚ to cook food. In addition to this technology

The Heat is about story of two brothers Carlos and Miguel or Michael (to his friends) Arroyo. Michael Arroyo has a pitching arm that throws serious heat. But his firepower is nothing compared to the heat Michael faces in his day-to-day life. Newly orphaned after his father led the family’s escape from Cuba‚ Michael’s only family is his seventeen-year-old brother Carlos. The Mimetic theory of this story is tell not only a great well driven story‚ but it is also tells a story of how it is to be an
