The present invention relates to a bone substitute comprising a core based on hydroxyapatite (HA), obtained from at least one porous wood, or based on collagen fibres and hydroxyapatite, and a shell, based on hydroxyapatite (HA) or silicon carbide (SiC), obtained from at least one wood having a lower porosity than the at least one wood of the core. The porous wood has a total porosity of between 60% and 95%, preferably between 65% and 85%, and it is selected from amongst the choices of rattan, pine, abachi and balsa wood. The wood of the shell has a porosity of between 20% and 60%, preferably between 30% and 50%. The bone substitute is utilized for the substitution and regeneration of bone, preferably for bones subjected to mechanical loads, such as long bones of the leg and arm, preferably the tibia, metatarsus, femur, humerus or radius.

摘要:
A substance applying apparatus for applying a substance to an application location. An application element having a wetting body is partially received in an inner tube and the inner tube is received in an outer tube. A fluid connection between the inner space of the inner tube and the inner space of the outer tube is produced by the application of pressure on the substance applying apparatus. The inner tube is comprised of a softer material than the outer tube and at least the bottom of the inner tube is deformable upon the application of pressure on the substance applying apparatus.
摘要:
A mixing arrangement and method for mixing a substance for the field of dentistry are provided, with the production of the substance requiring at least one base material and one reactant. A catalyst is applied to a base surface as reactant in a solid or semi-solid layer. The unit comprising catalyst and base is prefabricated, and the base material, particularly in liquid form, can be applied or introduced to the base surface that is provided with the catalyst prior to using the substance. The substance can be applied ready for use by means of an application element after the catalyst and base material have been mixed.

The enamelled cookware has a deep drawn shell of steel plate, placed beneath the base of which is a copper sheet. The latter is covered with a base plate comprising steel plate. The copper sheet is alloyed with the adjacent steel plates by high temperature brazing. An improvement in the cooking characteristics of the cookware is thus achieved. The latter is subsequently enamelled.
摘要:
A sampled analog signal is filtered by a short-term prediction filter. The result, a segmented residual signal, is transformed from a time domain to a frequency domain into several frequency components, each having a frequency-component amplitude. If a number of new amplitudes is calculated by combining the several frequency-component amplitudes, such that the number of new amplitudes is smaller than the several frequency-component amplitudes, a more efficient coder is created. The reduction of the quality of speech coding, due to loss of information, could be decreased if this calculation is based on the so-called Bark scale (critical frequency bands). In a corresponding speech decoder, at the hand of the number of new amplitudes several new frequency-component amplitude are calculated (the number of new amplitudes being smaller than the several new frequency-component amplitudes), which then are inverse transformed from a frequency domain to a time domain into new subsegments. These new subsegments are inverse filtered by an inverse short-term prediction filter to generate a signal which is representative for a sample analog signal.
摘要:
The invention relates to a process for preparing pyromellitic dianhydride (PMDA) by heterogeneously catalyzed oxidation in the gas phase by means of a gas containing molecular oxygen. The process involves oxidizing benzaldehydes which are 2,4,5-trialkylated by C.sub.1 - to C.sub.3 -alkyl groups or mixtures of benzaldehydes which are 2,4,5-trialkylated by C.sub.1 - to C.sub.3 -alkyl groups and benzenes which are 1,2,4,5-tetraalkylated by C.sub.1 - to C.sub.3 -alkyl groups in the presence of a catalyst. The catalyst contains as active components 5% to 95% by weight of one or more transition-metal oxides of sub-group IV of the Periodic Table of the Elements, from 1% to 50% by weight of one or more transition-metal oxides of sub-group V of the Periodic Table of the Elements. The catalyst also contains from 0% to 10% by weight of one or more oxides of elements of main group I of the Periodic Table of the Elements and/or from 0% to 50% by weight of one or more oxides of elements of main groups III, IV and V of the Periodic Table of the Elements and of elements of sub-groups VI and VII of the Periodic Table of the Elements. The indicated percentages by weight are based in each case on the total weight of the active components and add to 100% by weight.
