What causes a mushy material to form around a total knee replacement and cause it to fail?
i have knocking in the knee after total knee replacement is this normal
Aristotle used the Four Causes to explain an object's transferral from potentiality to actuality. The material cause, formal cause, efficient cause and final cause take something from an idea to reality. They are accurate to a degree but have several flaws and faults. A problem with the four causes is that they rely on experience. Plato argued that experience was unreliable as it changes from person to person - we cannot be sure that chairs…
A volcano cannot kill people. It is the amount of energy liberated from the volcano that causes harm. The enormous amout of heat energy liberated from the volcano causes the increase in temperature of the surroundings. If the temperature reaches the ignition value of the material, the material catches fire and hence causes damage. If the heat energy is very huge, it can cause damage to the surrounding life too.
There is no such thing as a material that causes Acetone to become combustible because it is extreemly flammable on its own. Any spark or flame of any sort will cause it to ignite. It is heavier than air so the vapors can travel along the ground to an ignition source and then the flames will travel back to the can of acetone.
The replacement of your boiler sound as if it is a maintenance issue and not something that could be covered by your homeowner's insurance policy. The damage would have to be caused by a covered cause such as a tornado, fire, vandalism, windstorm, etc. and I can't think of a way that it was damaged by one of the covered causes. Sorry.
What causes a random misfire on a Vw bora 1999 engine code APK Intermittent fault that requires replacement of cylinder 4 spark plug.?
Melted rock in the upper mantle and lower crust is under enormous pressure and is lighter than the material surrounding it. Because of these factors, it is compelled to rise, pushing through and pushing up the material above it. Once it reaches the surface, gravity and the molten material coming out after its expulsion cause it to move further.
Magma is formed by the partial melting of material within the Earth. The most common cause of this melting is due to changes in the melting temperature of this material. This is caused either by a decrease in the confining pressure of mantle material which causes a decease in the melting temperature and is technically known as adiabatic decompression melting or due to the presence of volatiles within the mantle material which exsolve from downgoing…
Normaly ,the atoms within a material are natural having an equal number of electrons(-) and protons(+) however friction bettween certain materials cause electrons to move from one material to the other.when electrons are added to a material the material has a negative charge from a material the material has a positive(+).Electrical charges caused by friction are called static electricity .Materials with like charges repel each other materials with unlike charges attract each other .
Convection currents in the mantle are believed to be the cause of plate movement. Molten material from the deep earth rises due to its heat and temperature, displacing material at the top, which moves to the side. This lateral movement causes the lithospheric plates to 'ride' the currents, thus moving the plates.
a smart material causes very few affects but they are great to use to re shape something like a spring when it is hit by the heat it can be remoulded and then heat hits it again and it can return to its original shape...I think? But anyway I am not sure how long it takes for a spring to be returned to its original shape and expectations.
