Introduction

Tooth development involves a complex process whereby teeth are formed from embryonic cells, and then eventually mature after erupting as evident in the mouth (Eckhardt, Jágr, Pataridis, & Mikšík, 2014). The development usually originates from mesoderm and ectoderm. At the ectoderm found in the oral cavity, there is the development of enamel and other tissues also come from associated mesenchyme. All teeth don’t develop at the same time, but rather in stages (Eckhardt, Jágr, Pataridis, & Mikšík, 2014). First buds are always observed in the region of anterior mandible, followed by anterior maxillary area then finally ...

Investigation of Solar cells

Introduction
Solar cells, also known as photovoltaic cells, rely on the photoelectric effect to convert the solar radiation into electric energy. Photoelectric effect refers to the tendency of materials to emit electrons when light is shown on them. The electrons dislodged from the surface of an object as a result of light being shown on the surface of such materials are referred to as photoelectrons. Not all materials exhibit the ability to emit electrons when placed along the path of light. Most with the ability to emit electrons are metals.
Silicon is a key ingredient of a solar cell. ...

Advantages and disadvantages of different types of photomultiplier tubes (PMT) in the context of the gamma camera
Tubes with GaP(Cs)
The Tubes with GaP(Cs) is an example of a PMT. Fliyckt and Marmonier (2009) state that one of its advantages as the high secondary emission coefficient of the GaP(Cs) which enables it to reduce the unexpected fluctuations of gain in most PMTs and therefore, improving the energy resolution. This is especially beneficial for light pulses that can allow the cathode produce only a few electrons. Since the GaP(Cs) also has a dynode, it allow the viewer ...

Introduction

A capacitor was originally called a condenser; it is an inactive two end points of an electrical part that is used to store energy electro-statically in an electric field. There are different forms of capacitors that differ extensively, but all of them have at least two different conductors separating them by insulators (dielectric) for instance one the construction, which has metal foils separated by a layers of thin insulating film. Capacitors are required in many common parts of an electrical circuit (Fawwaz, 2009).
When there is a significant variance across the conductors, an electric field is created transversely in the dielectric, ...

Introduction

Electromagnetism refers to the creation of a magnetic force from the movement of electrical charges. In order to find application in most electrical appliances, electromagnetism concerns the use of electric current to make electromagnets. This field of electricity is called Electrodynamics. It can also mean using magnetic field to induce an electric current. This field of electromagnetism is called Electromagnetic Induction. Almost all electrical appliances use one of the two types of electromagnetism mentioned above especially those with moving parts. This paper discusses the application of electromagnetism in a speaker.

Application of electromagnetism in a speaker

The speaker is basically an electronic transducer which converts electric energy ...

Polarized Sun Rays

Light wave has two components, the magnetic and electric components. These components are mutually perpendicular. The electric component forms the plane of oscillation for the wave. When an atom emits light wave in a single event, such wave has a fixed plane of oscillation. When several atoms emit light waves, the waves may not have same plane. Sun ray consists of various light waves, each with different planes of oscillation, and there is a random change in the light’s direction. This kind of light is unpolarized.
When light is polarized, the waves come in with the electric and magnetic field ...
