Corcoran at Wake Forest University uncovered evidence of this ability in 2009. “It started with a question that has been out there for a while‚ since the 1960’s-why do some moths produce clicking sounds when bats attack them?” Most tiger moths emit ultrasonic clicking sounds to signal how toxic they are to bats. But Bertholdia trigona emits ten times as much sound‚ “indicating that it might be serving a different purpose entirely”. Aaron and colleagues collected the moths and put them in a cage with

Humidity & Relative Humidity Humidity is defined as the amount of moisture in the air. Air contains a certain amount of water vapor. The amount of water vapor any mass of air can contain depends on the temperature of that air. The warmer the air is‚ the more water it can hold. A low relative humidity means that the air is dry and could hold a lot more moisture at that temperature. For example‚ at 20 degrees C (68 degrees F)‚ a cubic meter of air can hold a maximum of 18 grams of water. At

Nebulizers use oxygen‚ compressed air or ultrasonic power to break up medical solutions and suspensions into small aerosol droplets that can be directly inhaled from the mouthpiece of the device. They are often used in situations in which using an inhaler is difficult or ineffective. Nebulizers are

Chapter 2 Automated Highway Systems A major long-term element of Intelligent Transportation Systems research and development is Automated highway Systems (AHS). The AHS program is a broad international effort “to provide the basis for‚ and transition to‚ the next major performance upgrade of the vehicle/highway system through the use of automated vehicle control technology” [NAHSC96]. The detailed definition of the Automated Highway System is as follows [Plan93]: The term “fully automated

Abstract Therapeutic Ultrasound is a well established and commonly used practice in the field of Physiotherapy and Rehabilitative sciences. Primarily ultrasound is used in the treatment and repair of soft tissue lesion management used as thermal modality. However in recent practice the non-thermal aspects of Ultrasound as intervention are being employed. Evidence indicates the dose dependant

those designs. As soon as the project was assigned‚ we each chose a part to design. We also took detailed measurements of the parts on Creo. We took measurements of the small and large tires. We took note of all the necessary parts‚ such as the ultrasonic‚ electric motor‚ sound sensor‚ and other parts that we needed to build our project with. After reviewing all the parts that were available to us‚ the box with the lego parts and instructions‚ we read the instructions and collected the parts
