摘要:
The PMOS block (104) is connected between the virtual supply node (102) and output (101). The NMOS block (105) is connected between the virtual ground node (103) and output (101). The input of the balancing inverter chain (200, 300, 400) is connected to the output O (101). The balancing inverter chain is composed of at least one inverter and the output of the chain is the output (Y) of the structure. The static CMOS circuit (100) is supplemented with any combination of the following circuits. The virtual supply node (102) is connected to the supply rail by a serial P-type transistor (111), which gate (G), is connected to the ground rail. The virtual ground node (103) is connected to the ground rail by the serial N-type transistor (112), which gate (G) is connected to the supply rail. The virtual supply node (102) is connected to the output (101) by the complementary P-type transistor (121). The virtual ground node (103) is connected to the output (101) by the N-type complementary transistor (122).

摘要:
The subject of the invention is a bioactive nanocomposite layer prepared by the combination of electrospinning and electroblowing of a collagen solution comprising hydroxyapatite nanoparticles and poly(ethylene oxide), where, after the preparation and the crosslinking, the layer consists of 75 to 100 wt. % of collagen type I fibres, 5 - 15 wt. % of hydroxyapatite, and 0 - 1 wt. % of poly(ethylene oxide). The subject of this invention is also a method of production of said layer and a method of depositing antibiotics for a more effective releasing thereof without increasing the cytotoxicity. Said method comprises the impregnation of crosslinked sterilized collagen/hydroxyapatite layers with antibiotics in the form of a solution. The subject of the invention also comprises orthopaedic and dental implants based on metal or metal alloys, electrostatically coated with said composite layer based on collagen nanofibers with integrated hydroxyapatite nanoparticles and an antibiotic or a combination of antibiotics.

摘要:
Optical set-up displaying X-ray radiation with wavelength ? consists of monocrystal (1) with atomic planes (2) in parallel with optical axis (3). The mutual distance of the atomic planes in resting state without the force is d0. Cross section (S) of the monocrystal (1) is variable. With respect to the optical axis (3) the farther and/or closer side of monocrystal (1), which is orthogonal to this optical axis (3), is equipped with a device creating and maintaining pull or push force (F) in direction orthogonal to atomic planes (2) of such monocrystal (1).
