![]() Bering Standard Time – Before Alaska Standard Time was adopted across almost all of Alaska (other than the Aleutian Islands, which adopted the Hawaii–Aleutian Time Zone) in 1983, Nome, and the Aleutian Islands were previously in Bering Standard time.Samoa – Time in Samoa advanced 24 hours to the eastern hemisphere side of the International Date Line by skipping December 30, 2011.Tokelau – Time in Tokelau advanced 24 hours to the eastern hemisphere side of the International Date Line by skipping December 30, 2011.Phoenix Islands (of which only Canton Island is inhabited) (Phoenix Islands Time) advanced 24 hours to the eastern hemisphere side of the International Date Line by skipping December 31, 1994.Principal settlements: Alofi, Pago Pago, Tafuna Oceania Pacific Ocean Polynesia This is the latest inhabited time zone, meaning this is the last inhabited time zone to celebrate the New Year, as the world's latest time zone ( UTC-12:00) is completely uninhabited. This time is used in Niue, American Samoa, Swains Island, and parts of the United States Minor Outlying Islands. UTC−11:00 is an identifier for a time offset from UTC of −11:00. ![]() UTC−11:00: blue (December), orange (June), yellow (year-round), light blue (sea areas) The plan is to study a human total hip prosthesis with hydroxyl-apatite coating for chemical fixation to bone.01:27, 25 September 2023 UTC−11:00 Suppose you want to convert 0.85 MPa into pounds per square inch. ![]() For example, to convert 10 kPa to psi, you can use the following formula: psi kilopascal 0.14503773779. Hydroxyl-apatite coatings permit an implant fixation far superior to current methods using either cemented or cementless techniques. To convert kilopascal to psi, multiply the kilopascal value by 0.14503773779 or divide by 6.89475729. The hypothetical mechanism of bone bonding is chemical. Bony defects up to 2 mm in depth were filled with bone within six weeks. psi MPa The calculators available on this website are intended for informational and. How to convert Psi to Megapascal 1 psi (Psi) is equal to 0.00689 megapascal (MPa). The apatite-coated implants were rigidly fixed within three weeks with demonstrable bone formation up to the implant surface. Please enter values then click on Calculate. Uncoated prostheses were surrounded by fibrous tissue and were easily extracted from the femur at any postoperative time. The calculation for converting psi (lbs/sq in) into MPa is derived as follows: 1 MPa 1,000,000 pascals (Pa) 1 psi 6,894.76 pascals (Pa) MPa value x. In a canine total hip arthroplasty study, the apatite-coated implants proved far superior to the uncoated controls. Histologic sections confirm the close bonding between apatite coating and living bone. megapascal (MPa), gigapascal (GPa), pound per yd (lb/yd), pound per ft (lb/ft), pound per in (lb/in or psi), poundal per ft (pdl/ft), short ton per ft. In a plug implant study designed to discount mechanical retention, a bone bonding shear strength of 64 MPa (9280 psi) was achieved, comparable to the strength of cortical bone. The static tensile substrate bond strength of the apatite coating is in excess of 85 megapascals (MPa) (12,000 psi). Plasma-sprayed apatite coatings on titanium substrates overcome the fatigue problem. Sintered hydroxyl-apatite implants form very tight bonds with living bone but are susceptible to fatigue failure.
