research into the propagation of microwaves. Origin(s): One origin of microwaves include a maser‚ which is similar to a laser but it runs on microwaves. Wavelength and Frequency Range: The range for microwaves include super-high frequency (SHF) (3-30 Ghz)‚ ultra-high frequency (UHF) (0.3-3 Ghz)‚ and extremely-high frequency (EHF) (30-300 Ghz) signals. The wavelength for a microwave ranges from 1mm-1m. Where in the Spectrum the Waves are Located: Towards the start of the electromagnetic spectrum

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

Abstract The basic principle of Mendelian inheritance was studied using the fruit fly‚ Drosophila Melanogaster. A Cinnabar Brown female was crossed with Wild Type male. The flies were mated in a jar containing a nutrient medium and then placed in an incubator. The experiment was conducted over a period of 5 weeks. Cinnabar (cn) and brown (bw) are two loci in Drosophila with recessive eye colour mutations. Mutations in cn cause a bright red eye and mutations in bw cause a brown eye. Double mutants

as all essential components of a radio: antenna‚ tunable band pass filter‚ amplifier and demodulator. A direct current voltage source as applied by a battery powers the radio. Using the carrier waves in the commercially 40-400 MHz range and both frequency and modulated techniques it demonstrated successfully. The white paper reveals about the working of a nano radio with carbon nano tube and electrodes. The carbon nano tube plays a very crucial role in the operation of a nano

transceiver is studied and power-efficient circuits is designed for the transceiver. ABOUT UWB Ultrawide band technology is a wireless technology to transmit large amount of digital data as modulated coded impulses over a very wide spectrum of frequency with very low power for a short distance.In 2002‚the Federal Communications Commission allows UWB Communication in the 3.1-10.6 GHz band having a -10 dB bandwidth greater than 500 MHz and a maximum equivalent isotropic radiated power spectral

Cystic Fibrosis: Description‚ signs and symptoms: Cystic fibrosis is a genetic disorder‚ which is acquired at conception and therefore present at birth. The disorder is entirely caused by one pair of genes. People with cystic fibrosis produce abnormally thick‚ stick mucus in the linings of internal organs such as the lungs and intestines. The most common signs are persistent coughing‚ excessive sweating leading to salty skin‚ huge appetite but poor weight gain‚ and pale‚ oily‚ very smelly faeces

Theory and Synthesis Frequency: Frequency means the number of cycles per second and depending on the amount of cycles per second determines how high or low pitched the sound is and the time that it takes to complete one cycle is called the period. Frequency is measured in Hertz (Hz). And An average human is able to hear sounds between 20Hz and 20‚000Hz. As the cycles per second increases‚ the smaller the wavelengths become‚ therefore there is a higher frequency which will cause the pitch
