Zirconia, ZrO2, was synthesized by calcination of pure, sulfate-impregnated, and phosphate-impregnated Zr(OH)4 at different temperatures in the range from 600 to 1100°C for 5 h. Weight variant and invariant processes involved were monitored by thermogravimetry, differential thermal analysis and differential scanning calorimetry. The bulk structure and phase composition of the zirconias thus produced were characterized by X-ray powder diffractometry, infrared absorption spectroscopy and Raman scattering spectroscopy. The results have been correlated, so as to reveal the influence of the sulfate and phosphate additives on the zirconia polymorphic transitions as a function of temperature. Accordingly, phosphate species have been revealed to stabilize or influence stabilization of cubic-structured zirconia at temperatures as low as 600-900°C, where it is otherwise unstable. IR- and LRa-observed formation of Zr2P2O7 species (cubic-structured) is suggested to act as seed species for the stabilized cubic structure of zirconia. An analogous stabilizing influence was revealed for sulfate species, however, toward cubic and/or tetragonal zirconia, and functions within the thermal stability range of the sulfate (i.e. up to 720°C).
Drug polymorphism is a customerÕs variation in response to a drug is by gender, body composition, size and age. The first polymorphism was first labelled over 40 years ago.
Polymorphism and Allotropy are same thing. Polymorphism is used for compounds and the allotropy is reserved for elements. You can go for XRD to check the crystal structure and their composition to distinguish.

the polymorphism is only balanced when the dominate trait is recessive in the cell which came from the daughter cell after division, hence the dominate characteristics.

Polymorphism means multiple form of a function, variable or object. In Computer Science, polymorphism is a programming language feature that allows values of different data types to be handles using a common interface. There are three types : Ad-Hoc Polymosphism, Parametric Polymorphism, Subtype/Inclusion Polymorphism. Source: Wikipedia.
Polymorphism is common with barbiturates, steroids, and sulphonamides.
Yes, polymorphism exists between the prokaryotes.
Static polymorphism is used the concept of early binding or we can say compile time binding where as dynamic polymorphism used the concept of late binding or run time binding.
One can detect polymorphism by genetic marker using single-nucleotide polymorphism which is able to even tell mutation of a gene.
Drug polymorphism is a customerÕs variation in response to a drug is by gender, body composition, size and age. The first polymorphism was first labelled over 40 years ago.
compiler can decide which form of the object should be invoked during compile time.this type of polymorphism is know as compile time polymorphism
No. Interfaces in Java are a construct to get polymorphism ( subtype polymorphism ) working in Java, but they are not a "kind" of polymorphism. In polymorphism happens when two objects respond to the same message ( method call ) in different way ( hence poly -> many, morphism -> way or shape : polymorphism -> many ways). In Java to be able to send the same message to two different objects you have to either inherit the same parent, or implement the same interface.
Polymorphism is the changing of one subject to an altered state. There are actually two areas of study where polymorphism would be particularly common: chemistry and web programming.
Runtime polymorphism is also called as method overriding, late binding or dynamic polymorphism. It is when a method in a subclass overrides a method in its super class with the same name and signature.
