A drilling and vibratory jarring device is provided. The method includes obtaining measurements corresponding to a first object with at least one sensor, the at least one sensor providing one or more first track IDs for the measurements. Each channel can be adapted to receive a predetermined type of content for access on the mobile device. The beam tree data structure is then accessed for real-time computation and auralization of propagation paths to an arbitrary receiver location. Thus, the tourniquet may be applied, manipulated and tightened by the wearer, even if the wearer is limited to the use of a single hand. In particular the object of the invention is a gene transfer vector and host cells transduced by the vector, the vector containing a transgene and a nucleic acid sequence coding for CD34, a fragment of suitable for use in procedures for identification andor selection of genetically modified cells and in gene therapy.
