Paraphrasing for all the answering of tutorial question
From here it goes through another amplifier and enters the receiver unit to be translated into a lower baseband frequency. It is then filtered and digitized to become part of the central computer’s memory.Since the construction of magnets is prone to human error and can’t be absolutely perfect, a minor deviation of coil positioning or permanent magnet faces is enough to generate impurities which have to remove by shimming. For example, when magnets are energized, the impact of the internal

Paraphrasing for all tutorials answering of questions
Coherence takes place in the transverse plane and is described as "the degree to which the individual magnetization vectors align in the same direction".  The net magnetization or the sum of these vectors produces MR signals while precessing within the RF receiver coil. During dephasing, the degree of vectors alignment is reduced, the signal is lost and the net magnetization decays. If 2 vectors are aligned in the same direction within the transverse plane, then they are in-phase. After a very

If the correlation coefficient is negative, then one variable is going down as the other variable goes up. The correlation coefficient is the same if you swap the order of the variables you are considering.If the correlation coefficient measures 1, then the two variables are maximally correlated. What this means in our case, is that the position x and the time t are maximally correlated, in other words, there is a strong relationship between them so that if one goes up the other will do the

Phys 1070: Space Mission
This specific design necessarily considered the demands of exploration beyond the orbit of Mars. In his early stages the Cassini was constructed in conjunction with the Comet Asteroid Flyby (CRAF); however, the later was scrapped because of budget cuts, to ensure the Cassini craft could survive (Harland). The ultimate spacecraft design was the largest and most complex interplanetary built to date. The spacecraft measures twenty-two feet high and more than thirteen feet wide (Harland). This

Hot vapor from the compressor undergoes isothermal and isobaric condensation, releasing latent heat of vaporization. The condenser tubes are designed and arranged to maximize their surface area to absorb heat from anything stored in the refrigerator.The compressed vapor temperature is higher than room temperature as the vapor goes into the condenser coils, thus heat will flow out of the refrigerant and be taken away by the surrounding air. However, the vapor pressure remains constant as it gets

(If an overall system uptime of >95% is desired, this can translate into a reliability factor of >98% for the accelerator.) Additionally, it is important to consider the beam time structure produced by the accelerator, because this will play a role in the determination of the beam spreading system that can be used. Figure 1 below shows a typical layout for technologies on the treatment floor of a multiroom proton therapy facility.The charged particle beam path in a simple cyclotron is shown in

The half-life of carbon is the process used by the geologist and the scientist indetermination of the isotopes of an element so that the age of the rock can be determined.Climate and the climatic change are caused by the continued human activity in the exhaustion of the earth resources. The man’s activity causes global warming hence the change in climate. The ocean circulation affects climate since they cause the sea and the land breezes which cause convectional rainfall. This has an effect

The hanging mass is attached at the end of the string to provide tension. When a horizontal pick is used to pluck the string just at the pulley, a pulse is created in the string and travels along it in form of a disturbance. A timer is started by the pulse created in the wire by the plucking effect. The timer continues recording the time until the traveling pulse reaches the sensor, which stops it. When the mass attached to the other end of the string is changed, the time taken by the pulse to

When electrons are moving against the same direction it causes friction, this is manifested in form of heat.at the same time the readings of ammeter changes. The concentration of heat in filament will force the bulb to glow.In the cases of short circuit, the bulb will stop glowing because there is no complete flow of electrons. There will be any resistance because the circuit is incomplete. When we use batteries in the above set up, the battery will run short of the charge because the electrons

Professionalism in Aviation
Therefore, being a flight attendant, pilot or any other personnel in the aviation industry calls for the joint responsibility for the comfort and safety of customers. That means that even the most basic tasks such as greeting passengers are conducted professionally. Therefore, everyone who handles aircraft as well as passengers must be mentally fit for their duties. Mental fitness for duty may be a personal and ethical initiative, but the management in the aviation industry must also

Physics of forces and types of forces in the mechaincal energy and thermal energy involved including why and how newtons laws are in and satisfied in the operation of a steam turbine pump.
These impulse turbines are made up of rings of nozzles followed by rings of blades. Notably, high pressure, high energy steam is allowed into the nozzles then it is let into a region of lower pressure, high velocity in a different direction. As a result, the changing direction and high velocity produce impulsive force that acts in the direction of rotation of the turbines. Thus according to Newtons second law of motion, the rate of change in momentum is directly proportional to the external

Climate is one of the many factors that make life on earth possible. Within millions of years, the temperatures of the earth have changed to fit bounds that are life-sustaining. The icehouse interval is characterised by three major glaciations in the Phanerozoic Eon. The first one is the Late Ordovician that occurred about 430 million years ago, the second one is the PermoCarboniferous period whose period spanned 325-240 million years ago and lastly the Late Tertiary which started about 35

The vibrations associated with the earthquakes makes the rocks underground to break. This leads to release of lots of energy from beneath the ground. This energy is very strong and is capable of causing massive destructions to the landscape itself, infrastructure, structures as well as property (Brumbaugh, 2010). Moreover, the energy released from the underground following the incidences of earthquake can sometimes result to massive loss of lives.In most instances, the energy from the

Positron emission tomography
When the positrons arrive at thermal energies, they begin connecting with electrons either by annihilation, which produces two 511 keV photons that are anti-parallel in the positronís frame, or through development of a hydrogen-like orbiting couple known as positronium. At its foundation condition, positronium has two types’ of- ortho-positronium, where the spins of the electron and positron are parallel, and para-positronium, where the spins are anti-parallel. However, Para-positronium

The decay depends on the half-life of the nuclide. Half-life is the duration/time that a nucleus takes to be halved.Positrons refer to the subatomic molecules that are equal in mass to an electron with characteristic of carrying a positive charge. When the positron decay (β+), its nuclei changes one of the core protons (p) to a neutron (n), while emitting positron (β+) to attain a positively charged nature referred to as neutrino (ν).Upon the release from the initial nucleus, the high

The challenges tied to the Standard Model on the other hand relate to the absence of outcomes in experiments that would totally verify the theory. Until the Higgs Boson can be completely verified empirically for instance, there remain large holes in the theory that need to be validated, as the Higgs Boson is one of the most fundamental aspects of the Standard Model (Shears, 2012). The experiments at the Large Hadron Collider or LHC has confirmed the existence of a particle with the predicted
