electromagnetic devices claim to affect the nervous system of small rodents, which allows them to stay away from said area. A new solution is to combine ultrasonic waves with electromagnetic waves to repel pests, the ultrasonic waves will produce a frequency that cannot be heard by humans, but bugs will hear as a warning. The electromagnetic waves will be used to affect the nervous system of the bugs, but since their nervous system isn 't in affected the same way as small rodents, which is what…
RADIOWAVE OUTDOOR PROPAGATION MODELS General definition: • They are empirical mathematical formulation for the characterization of radio wave propagation as a function of frequency, distance and other conditions. • These models predict the path loss (i.e. the reduction in power density of an electromagnetic wave as it propagates through space or underground) of a transmitter and also the effective coverage area of transmitter. We know that when a signal travels from a wireless channel, it…
the first step I would suggest is to remove the low ends. Play around with the eq to remove the rumbles in the track and make it as clean as possible before putting on any effects or compression. Use a high pass filter to remove most of the low frequencies like the background noise. Use drastic eq to find out where the vocalists sound good in the mix which is a well known thing to the engineers. Eq may differ with the kind of genre you are mixing. Ten years ago, it was safe to make a statement…
INTRODUCTION Millimeter wave therapy is the exposure to a frequency that ranges from 30-300 GHz. This frequency is located in the radio frequency region of the electromagnetic spectrum. Due to the extremely small wavelength the frequency will only penetrate up to 2 mm of skin. In therapy the frequency is irradiated on certain parts of the tissue, depending on the specific treatment and energy it is deposited in the skin causing a variety of beneficial reactions. In the Former Soviet Union (FSU)…
How does sound travel through the three parts of the ear? There are three parts of the ear in which sound must travel; the outer, middle, and inner ear. Sound does not simply go from the outer ear to the inner ear; it must become four different types of energy in order to pass through. These types of energy are acoustic, mechanical, hydraulic, and electrical. Ears work in a pair to help us localize and discriminate where sounds are coming from in our surroundings. It seems hard to believe but…
Genetic Analysis in Plants Trev Mumm and Peter Masinelli Life 120 – Lab Section 122 April 28th, 2014 ABSTRACT We completed this lab to classify and count phenotypic traits in plant crosses with one or two segregating mutations, and we also learned how to use the Chi-Square test as a tool to access the statistical significance data collected from a genetic cross. Our hypothesis for the experiment that included green and albino corn genetics, was that the ratio of green to albino…
Johann Mendel was born on July 20, 1822 in Heinzendorf bei Odrau, a small village in the Austrian Empire. Mendel’s parents were poor farmers who made many sacrifices to pay for his education. Mendel did well throughout his high school career and, at age 18, he entered the University of Olomouc in 1840. During his time at the University, Mendel studied mathematics, philosophy, and physics. In 1843, at age 21, Mendel experienced financial troubles. Professor Friedrich Franz, a physicist,…
Ashley Kuroki Science 9/8/15 Insect Olympiad Jigsaw Group B: The Difference between Problematic Insects Moths and butterflies- Moths and butterflies don’t have that many differences. However, moths have feathery antennae while the butterflies have thin antennae. Moths are nocturnal and butterflies are active during the day. Those are the main differences. Even though butterflies have better looking wings than a moth’s, there are some moths that look exactly like a butterfly like the Madagascan…
Confirmation of Mendel’s Law of Segregation I. In Biology class the past few weeks we have been learning about Gregor Mendel. Gregor Mendel is often called the father of modern genetics. Mendel developed the theory of inheritance several decades before the observance of chromosomes via microscope. In Biology lab the past two weeks I completed a series of tests using fast plants, Brassica rapa. The objective of this experiment was to study the Mendelian laws of genetics as they applied to…
