Abstract: In order to provide a hydroxyapatite that can be used without reservation in the food industry, a hydroxyapatite powder is provided composed of primary particles. The median size of the primary particles from which the powder is made is >0.10 ?m and the aspect ratio of the primary particles is <5. The specific surface area of the hydroxyapatite powder is ?10 m2/g, and the bulk density is >550 g/l. Also disclosed is a method with which such a hydroxyapatite powder can be obtained.

Abstract: A method and a system for diagnosing the operating state of one or more railroad components of a railroad network for rail transport. The railroad components each have at least a first measuring device for measuring first measurement values of at least one measurement variable for describing the operating state of the railroad component. The novel method includes the following steps: measuring the first measurement values by way of the first measuring device; measuring additional, second measurement values, which are independent of the operating state of the railroad components, by way of at least one additional, second measuring device; transmitting the measurement values to a control center situated along the tracks; evaluating the measurement values in the control center by way of a predefined algorithm, and providing at least one result of the evaluation as an output.

Abstract: A method and a system for diagnosing one or more rail vehicles, each of which has at least one measuring device for measuring measurement values of at least one measurement variable. The method includes the following steps: measuring measurement values by way of at least one measuring device of at least one rail vehicle; transmitting the measurement values from the rail vehicle to a control center situated along the track; evaluating the measurement values in the control center by means of a predefined algorithm, and providing a result of the evaluation as an output.
