Abstract: A road vehicle has steerable front and rear wheels, the rear wheels being steered by an electro-hydraulic system responsive to the manual control input to the front wheels. The hydraulic actuator of the system is biased to the straight-ahead steering position by springs, so that the rear wheels are centered in the event of electric or hydraulic failure, and an hydraulically restrained latch element is spring biased to then latch the actuator piston in its centered position.

Abstract: Cyclic polycarbonate oligomers are polymerized to linear polycarbonates by contact with a polycarbonate formation catalyst which has been modified by contacting the same with at least one diaryl carbonate, preferably diphenyl carbonate. Said modification decrease the polymerization rate or introduces an induction period into the polymerization reaction.

Abstract translation: 环状聚碳酸酯低聚物通过与聚碳酸酯形成催化剂接触而聚合成线性聚碳酸酯，聚碳酸酯形成催化剂通过使其与至少一种碳酸二芳基酯，优选碳酸二苯酯接触来改性。 所述改性降低聚合速率或将引入期引入聚合反应。

Abstract: A method to increase the efficiency of transduction of hematopoietic and other cells by retroviruses includes infecting the cells in the presence of fibronectin or fibronectin fragments. The fibronectin and fibronectin fragments significantly enhance retroviral-mediated gene transfer into the cells, particularly hematopoietic cells including committed progenitors and primitive hematopoietic stem cells. The invention also provides improved methods for somatic gene therapy capitalizing on enhanced gene transfer, hematopoietic cellular populations, and novel constructs for enhancing retroviral-mediated DNA transfer into cells and their use.
