In the present article‚ the authors investigate the use of flame spheroidized hydroxyapatite particulates in a PEEK polymer for usage as bone analogue materials. Metallic implants have been used for orthopedic implants in the past‚ but polymeric implants have been explored due to stress-shielding issues associated with metallic implants. Wolf’s Law states that if bone is not subjected to mechanical stimuli‚ then it will be absorbed (Uhthoff and Dubuc‚ 1971). Therefore‚ it is important to develop

As he is attempting to calm the distraught women‚ his peripheral vision captures a man lunging at him with a metallic object from an adjoining room. Officer Smith leaps aside‚ pulls his weapon‚ and fatally shoots the man only to find the metallic object was a broken metal towel rod. Even though his body camera was functioning correctly it did not capture the totality of the event‚ and the alleged victim fails to corroborate his

Renewable natural resources are present in abundant supply that will last for ever like sunlight‚ wind‚ water etc and non renewable natural resources are fossil fuels‚ metallic minerals like iron‚ copper‚ zinc‚ aluminum and non metallic minerals like sand clay phosphate etc. These days we are so much dependent on non renewable resources. Life seems impossible without these resources. We have only limited supply of fossil fuels and consumption of the

they can be classified into a few simple categories based on type of bonding that exists among the atoms in the substance. Bonds are chemical forces that hold atoms together to form molecules or compounds. These categories are ionic‚ molecular and metallic substances. In ionic compounds valence electrons are transferred from one atom to another‚ resulting in formation of ions of opposite charge. Metals will lose electrons to form cations (positively charged) and non-metals can gain electrons to form

One hour‚ 60 minutes or 3600 seconds was all it took. All it took for reality to become meaningless. As I lay here‚ I can taste blood in my mouth: hot‚ wet and metallic. I can feel the forever expanding pool or crimson blood cascading from my partially severed body. My nostrils are filled with the smell of gnarled fabric and the acrid scent of roasting rubber. Silence. It drowns me‚ it pulls and tugs and screams a thousand words never to be heard. Nothingness. 3600 seconds earlier. In an infinite
