The images a MRI machine actually present are the water molecules that make up most of our bodies systems and organs. Water molecules consist of oxygen and hydrogen atoms, the core of which is a nucleus, a single proton. The protons have a basic property called nuclear spin as well as an electrical charge which makes them act like little magnets. When the magnetic field makes the spinning protons wiggle, the stronger the magnetic field, the faster the wiggle. Nuclei wiggle at roughly 50 million…

Today we might know an atom being the smallest piece of an element that represent an element, but you might not know the whole story. It all being in 1803, when a curious guy, known as John Dalton, who proposed an “atomic theory” with spherical solid atoms based upon measurable properties of mass. Later on Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. John Dalton's research not only changed the face of…

subatomic particles: electrons, protons and neutrons. For which the Nucleus contains the Protons and Neutrons, while electrons orbit around the nucleus. The atom is a fundamental piece of matter. Atoms are the building blocks of matter and matter builds up the Universe. A Valence Electron is an electron, which is a subatomic particle of an atom. Valence electrons are located in the outermost shell of the atom, these can be transferred to or shared with another atom. Valence electrons are…

The arrangement of electrons is distributed between four orbital’s; S, P, D and F. Each orbital is a different shape and holds a different number of electrons. Orbital S is a circle and it contains two electrons and orbital P has three different shells. One shell is an infinity sign, the next is a crooked infinity sign and the last is shaped like an upright infinity sign. Each shell can hold two electrons which allow orbital P to hold six electrons, orbital D can hold ten electrons, and orbital…

the nucleus, the nucleus contains the protons, which have a positive electric charge, along with the neutrons, which have a neutral charge and is slightly heavier in mass when compared to a proton. Along the outer rings of the atom the electrons orbit, the electrons have a negative electric charge, as well as the smallest mass out of the three. “The nuclear forces” is a common name used to describe the connection between the protons and neutrons in the nucleus. Nuclear stability is the stability…

fundamental unit of a chemical compound that can take part in a chemical reaction. Molecules are three-dimensional entities and therefore should be depicted in three dimensions. My group decided on the claim that as electrons are bonded to a central atom, the greater the electron repulsion, causing an increase in the bond angles. Bond angles are the angles that are formed between two adjacent bonds on the same central atom. We analyzed the information that we discovered on the website that…

is to remove the synchromesh components within a manual transmission and replace them with Zeroshift rings, Figure 1. Synchronization is performed externally with the assistance of torque intervention performed by the engine control unit and an automated clutch (standard equipment in an AMT).  The Zeroshift rings act as a pair and represent a dog engagement type transmission. The unacceptable backlash found in dog engagement transmissions is eliminated by splitting the dog into two halves. The…

three speed transmission. The TH350 transmission was introduced in the 1969 model year as the successor to the GM Power glide automatic transmission. The TH350 transmission was developed in a joint effort by the Chevrolet and Buick Automotive Corporations. The TH350 transmission it is also referred to as the CBC (Chevrolet-Buick Combined) 350. Soon after production the Turbo 350 quickly became known for its strength, versatility and compactness. The Hydra-Matic 350 transmission was…

Unit Standard 6852 Assessment Task 1: Throughout history, cable types have changed quite a lot, whether is be for reasons based on speed - or security. The most common one that is usually referred to as “ethernet cable” today is CAT cabling. The generic blue cable that end users recognise as their internet service - this has become one of the most developed cable types in IT history. From CAT3 to CAT7, many improvements have been made to improve the quality of the cabling, such as giving it a…

My job position did not require me to drive any vehicles with a manual transmission and respondent did not require other similarly situated employees not of my race or national origin to obtain a CDL for driving vehicles with manual and automatic transmissions.” Response: As articulated in the “Background” section, Mr. Casquejo was appointed to a Maintenance Specialist, Electrician Journey II position in the Facilities…
