It''s Elemental - The Element Calcium - Science Eduion …
Today, metallic calcium is obtained by displacing calcium atoms in lime with atoms of aluminum in hot, low-pressure containers. About 4.2% of the earth''s crust is composed of calcium. Due to its high reactivity with common materials, there is very little demand for metallic calcium.
Fluorapatite ceramics for bone tissue regeneration: …
Calcium phosphates, due to their similarity to the inorganic fraction of mineralized tissues, are of great importance in treatment of bone defects. In order to improve the biological activity of hydroxyapatite (HAP), its fluoride-substituted modifiion (FAP) was synthesized using the sol-gel method and calcined at three different temperatures in the range of 800–1200 °C.

Renal (Kidney) Stones - The Mini-Gastric Bypass
The Mini Gastric Bypass (MGB) is a Short, Simple, Successful, Reversible Laparoscopic gastric bypass weight loss surgery. The operation usually takes only 30 min., hospital stay less than 24 hours. The Mini Gastric Bypass (MGB) is low risk, has excellent long term weight loss, minimal pain and can be easily reversed or revised. The MGB decreases hunger (Ghrelin) and increases satiety/feeling
Use zirconium in a sentence | zirconium sentence examples
Cubic zirconia (often abbreviated CZ) is a lab-created crystalline cubic form of zirconium oxide stabilized with small quantities of other minerals, typically yttrium or calcium. 0 Diamonds can be found in many different colors, and so can CZ, depending on what different mineral oxides have been added to the zirconium oxide during crystal stabilization and cooling.
Types of Explosives - Science Toys | Science Toys
So far, we have discussed explosives by when they were invented, and later, to some extent, by their sensitivity to heat, friction, or shock. In this chapter, we will discuss the classes of explosive, which depends on the types molecules used (their chemistry), and

Lead Acid Battery - an overview | ScienceDirect Topics
Lead–calcium–(tin) alloys are used in maintenance-free automotive starting, lighting, ignition (SLI) batteries, in stationary batteries, and some traction batteries. It is essential that the correct calcium content and a suitable calcium–tin ratio is used.
Using Metal Detection Technology for Inspection of Beef …
To handle phase changes over time, the metal detector should utilize a phase tracking capability. Tracking works by automatically adjusting the product phase in real-time as the meat is inspected. Information from uncontaminated meat is fed back using a proprietary algorithm, maintaining performance as the ratio of conductive and magnetic product signals change.
