Corporate IoT – a path to intrusion. Several sources estimate that by the year 2020 some 50 billion IoT devices will be deployed worldwide. IoT devices are purposefully designed to connect to a network and many are simply connected to the internet with little management or oversight. Such devices still must be identifiable, maintained, and ...

Read More(Strontium may remain in the bones for as long as 7–10 years after the last dose.) Strontium has a chemical similarity to calcium and will replace calcium as the mineral in bone. Because strontium atoms are heavier than calcium atoms, swapping some of the calcium atoms with strontium atoms will make the bone mineral density appear to increase.
Read MoreThis effect was reversed after strontium withdrawal over 8 weeks. As calcium is used not only in bone but is also an important cellular signal in neurotransmitter release, muscle contraction and electrical conduction in the cardiac muscle. SrC may have adverse effects on these processes as well, which need to be studied further. ...
Read MoreAfter 6 weeks, both CPC and SrCPC scaffolds exhibited good biocompatibility and osseointegration. Fluorochrome labeling revealed that both scaffolds were penetrated by newly formed bone already after 4 weeks. Neither strontium doting nor mechanical loading significantly influenced early bone formation.
Read MoreFig. 3 shows the XRD patterns of different weight ratios of strontium sintered into calcium sulfate at 1100 °C. CaSO 4 phase was only detected in the CS, 1 W, 10 W, 20 W groups, but both phases of CaSO 4 and SrSO 4 were detected in the 50 W and 100 W groups. The XRD peaks shift to their left-hand side, indicating the replacement of Ca 2+ ions with larger Sr 2+ ions.
