Is there any test to determine the cardiovascular risk of patients with obesity? from the perspective of obesity?

We found tests to determine cardiovascular risk taking into account lipid profile, blood pressure, age, history of diabetes, other laboratories. But when weight is involved, there is a paradox. I...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

This will most likely be a case of trial and error. (definitely dependent on composition)

It greatly depends on how the ceramic powder holds together after CIPing, or whether you will need some kind of binder added (which may then need to be burnt out during sintering).

Shrinkage during sintering is also a critical phase (and possibly dependent on CIP pressure).

It may be possible to CIP your block oversize and then machine to the correct dimensions, taking into account sintering shrinkage, which would ensure your geometry remains.

Processing your powder via CIP and then sinter via the HIP process should ensure that your fabrication process is very repeatable and your resultant ceramic could obtain 100% theoretical density.

(hope this helps!)

Dear Alaa,

What is your ceramic material. Its depends on the ceramic what you are using. Some times it depends on the sintering time, temperature and heating rate, socking time and other parameters.

wish you good luck.
