Cysticerus

Cysticercus refers to a tapeworm larva which has a sac filled with fluid that contains scolex which is invaginated. It is normally located within the immediate host tissues, with the capability of developing into mature tapeworm when a desirable host feeds on it ("Cysticercus | Definition of Cysticercus by Merriam-Webster."). Cysticerci are responsible for causing an infection known as cysticercosis. There are several species of cysticerci. The two common species of cysticercus are Tanenia solium whose larva is known as Cysticercus cellulosae. It develops in the swine muscles frequently. The second species is the Taeniarhynchus saginatus. Its larva is known ...

Orange was one of the fruits found at the market. They are produced in Florida and California. Apart from the conventional oranges, there were organic oranges. The prices were different. The organic type was more expensive, simply because they were chemical free. They are grown using organic manures. Pests and diseases were controlled using purely biological means. Organic oranges have green and white USDA organic sticker to distinguish them from conventional oranges (Laroche, Bergeron, & Barbaro-Forleo, 2001). Purex is one of the commonly used laundry detergents in United States of America. This is an inorganic detergent characterized by its pretty ...

Thermal conductivity is defined as a material’s property to conduct heat. Heat transfer across materials occurs in materials that have lower thermal conductivity and transfers faster in materials with high conductivity. It is important to determine the thermal conductivity of materials since different materials are used for different applications. For instance, materials with high conductivity are more efficient when they are used as heat sinks since they can conduct heat away faster. Those with lower thermal conductivity are often used as insulators (Callister 78). The classical transfer of energy happens through conduction, radiation, convection or combination of all ...

Introduction

This proposal is about the physics of microwave oven. This includes the interaction of microwaves with metals and the generation of microwaves in magnetrons. The reason for choosing a microwave oven is because they are used common places like in homes and restaurants for warming food. A microwave is a wave that belongs the class of electromagnetic waves. They have frequencies ranging from 300 MHz to 300GHz and wavelengths ranging from 1 m to 1mm. (Bradshaw, Van & Swardt, 201)

Physics of the Microwave

A typical microwave oven consists of the magnetron, fan, power supply, waveguide, turntable and a base plate. The microwaves are ...
