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

I was so stoked to go swim with marine animals and couldn’t wait to feel the soft skin of a bottlenose dolphin on the palm of my hand. My mom was obsessed with dolphins two years ago. I’m not kidding. She had little dolphin statues in our living room for decorations and has a dolphin tattoo on her ankle. I was almost as excited as my
