Abstract: Processing algae includes liquefying algae to yield a mixture including biocrude oil, biochar, and an aqueous component, and treating the biochar to yield a nutrient composition including ammoniacal nitrogen and phosphate.

Abstract: A method for warning a motor vehicle of a collision with a rail vehicle, in which, using an electronic computing device arranged externally of the vehicle, first movement data of the rail vehicle, which characterize a position and/or a speed of the rail vehicle, are received from a sensor device permanently installed in a rail network and/or are determined as a function of an electronic timetable. A hazardous situation is determined as a function of the first movement data and position data of at least one level crossing, which position data characterize a position of the level crossing. A hazard information signal, which can be called up by the motor vehicle and characterizes the hazardous situation, is provided for the motor vehicle as a function of the hazardous situation.

Abstract: An orthopedic standing and walking aid and a method of supporting a person with such an orthopedic standing and walking aid. The orthopedic standing and walking aid comprises a carriage which is displaceably mounted on a running rail, an approximately C-shaped frame suspended from the carriage by a suspension device and a saddle which is arranged on the shaped frame approximately in linear alignment below the suspension device. The orthopedic standing and walking aid can be distinguished by a spring element arranged in the area between the carriage and the saddle so that the saddle is elastically supported in the vertical direction. The orthopedic standing and walking aid may also be distinguished by a height adjustment mechanism for adjusting the height of the saddle, which has a height adjustment spring element which exerts an upward preload on the saddle. This height adjustment mechanism can be designed to be lockable with one hand by means of a locking unit.

Abstract: A method and apparatus for checking the validity of an item of data stored for access by a first data processor of a data processing network having at least two interconnected data processors. The first data processor provides a second data processor with a copy of an item of data and the second data processor determines whether the item of data is valid. The second data processor then reports to the first data processor on the validity of the item of data so that the first data processor can prevent access to any invalid data.
