Abstract: A survey instrument comprising a single point and a point cloud measuring functionality, a communication interface, and a computing unit. The point cloud measuring functionality configured to emit a scanning beam along a first measuring axis and to advance the first measuring axis along a scanning pattern. The point cloud measuring functionality is configured to generate point cloud data representing a setting. The single point measuring functionality is configured to emit a measuring beam along a second measuring axis. The first measuring axis is referenced to the second measuring axis. The communication interface is configured to receive model data representing at least a part of the setting and comprising referencing data to an external coordinate system. The computing unit is configured to identify cardinal features in the point cloud data as well as in the model data.

Abstract: The present invention provides a new approach to creating novel polynucleotide sequences by point mutation and recombination in vitro of a set of parental sequences. The new polynucleotide sequences can be useful in themselves or they can be used for the templated synthesis of polymers, e.g. polypeptides composed of ?-amino acids as occurring naturally in protein synthesis or polymers comprised of ?-amino acids or other building blocks as described (Templated molecules).

Abstract: The gas or gas-carried suspended matter indicator tube includes a reagent therein for detecting gases or suspended matter in the gas which are passed through the tube. The tube is drawn down at each end and sealed. Each end of the tube or the portion of the tube at which the reagent ends, is retained by fixing elements, which comprise glass granules which are sintered.
