Door component and method
A door component for pivoting a movable door of a motor vehicle has a drive with an electric drive motor in order to influence a pivoting of the door between a closed setting and an open setting. A position measure for an angular setting of the door leaf and a speed parameter for an angular speed of the door leaf are detected by a position sensor. During a pivoting of the door leaf with the speed parameter, an electrical setpoint current intensity for the electric drive motor is ascertained, and an associated setpoint voltage is set. Then the current intensity flowing through the drive motor is ascertained. The setpoint voltage is increased if the current intensity is lower than the electrical setpoint current intensity, and the setpoint voltage is decreased if the current intensity is higher than the electrical setpoint current intensity. |

Generation of dendritic cells from monocytic dendritic precursor cells with GM-CSF in the absence of additional cytokines
The present invention it was determined that dendritic cells could be derived from various sources including peripheral blood monocytes in the presence of only GM-CSF without other cytokines if the monocytes were not activated. By preventing activation, such as by preventing binding of the cells to the surface of the culture vessel, the monocytes do not require the presence of additional cytokines, such as IL-4 or IL-13, to prevent differentiation into a non-dendritic cell lineage. The immature DCs generated and maintained in this manner were CD14− and expressed high levels of CD1a. Upon maturation by contact with an agent such as, for example, BCG and IFNγ, the cells were determined to express surface molecules typical of mature dendritic cells purified by prior methods and cultured in the presence of GM-CSF and IL-4. The mature dendritic cells produced from monocytes without activation and cultured in GM-CSF alone are suitable for use in dendritic cell-based immunotherapy methods, such as for use in the treatment of disease, including cancer. |

Method for the diimide hydrogenation of emulsified unsaturated polymers
The diimide hydrogenation of unsaturated elastomers in latex utilizing hydrazine and hydrogen peroxide or oxygen, is a metal-catalyzed process. Copper ion has been found to be the most superior catalyst for this reaction, requiring an extremely low concentration for optimal results. Generated diimide efficiently hydrogenates the polymer olefinic unsaturation while generating water and nitrogen as byproducts. With a falling hydrazine concentration during the hydrogenation process however, a competing copper-catalyzed process capable of generating hydroxyl, superoxide and/or copper-oxyl radicals becomes increasingly competitive. The ability of these radical species to abstract hydrogen from the polymer backbone to generate polymeric radicals, ultimately results in crosslinking that occurs concurrently with hydrogenation. The concept of an OH radical inactivating ligand (OIL) complexed with copper is demonstrated to ameliorate the crosslinking reaction. |
