Abstract: An electroluminescent device comprising: a first charge-carrier injecting layer for injecting positive charge carriers and a second charge-carrier injecting layer for injecting negative charge carriers, at least one of the charge-carrier injecting layers being patterned so as to comprise spaced-apart charge-injecting regions; an organic light-emitting layer located between the first and second charge-carrier injecting layers; and an unpatterned conductive polymer layer located between the organic light-emitting layer and the patterned charge-carrier injecting layer, the resistivity of the conductive polymer layer being sufficiently low to allow charge carriers to flow through it from the charge-injecting regions to generate light in the organic light-emitting layer but sufficiently high to resist lateral spreading of charge carriers beyond the charge-injecting regions.

Abstract: The present invention relates to methods of increasing the antigen presenting ability of monocytes by contacting them with an agent which increases the intracellular calcium level. Methods of obtaining the monocytes are also disclosed. In addition, the present invention relates to methods of inducing bone marrow progenitor cells and endothelial cells to express molecules involved in generating immune responses. Methods of modulating the expression of molecules involved in generating immune responses are also disclosed, as are methods of treating cancer and leukemia.

Abstract: A method for calculating the orientation of a geologic feature with respect to the axis of a wellbore drilled through earth formations. The method uses finely detailed measurements of a selected property of the earth formations made along the wall of the wellbore. The method includes the steps of segregating the finely detailed measurements by an angle subtended with respect to an arbitrary reference on the circumference of the wellbore. The measurements are further segregated into a selected axial interval along the wellbore. For each segment, for each subtended angle, the segregated measurements are spectrally analyzed with respect to spatial frequency. Coefficients of a best fit curve are determined for the phase components of the spectrally analyzed measurements with respect to the subtended angle. The orientation of the geologic feature is calculated from the best fit curve.

Abstract: A method of isolating dendritic cells is described. This method involves elutriating peripheral blood samples in at least four flow rates from an elutriation rotor. Calcium ionophore is used to stimulate monocytes isolated during the process into dendritic cells. Treatments for diseases involving re-introduction of activated dentritic cells are also described.

Abstract: A packing tube assembly which can easily be substituted for the conventional stuffing box on typical pumping wells to substantially increase the operational life of the packing involved. The assembly includes a mounting bushing for the packing tube having a tapered bore therein by which the rod on which the packing is mounted can be removed and reinserted from the top of the well without removing the packing tube.

Abstract: Apparatus for providing an indication of uterine activity in labor is described. Intrauterine pressure above the basal pressure existing between contractions is integrated over intervals of between ten and thirty minutes to give the required indication. An algorithm is disclosed for calculating dosage of a labor inducing substance, the algorithm containing safeguards to prevent hyperstimulation.
