- Tuberculosis (TB) is a major public health problem and the world's foremost cause of death from a single infectious agent. Despite the increasing number of TB patients who seek help in the private sector, there are few practical examples of how to create a public/private linkage of TB services. The paper presents a pilot service-linkage project between the public and private sector in TB control in Kathmandu Valley, Nepal. The study documents and examines the process of the service-linkage project through the undertaking of a longitudinal analytical case study. A detailed description of the project from formulation to a short-term evaluation is given. The analysis relates the activities and early outcomes of the service-linkage project to the context, characteristics and interactions of the organizations involved. The study reveals that although the involved organizations initially agreed on the objective of the service-linkage project, differences in capacity, motivation, environment and needs had implications for the implementation and short-term success of the project. The public sector, despite the will, did not have the structure or resources to engage with the private sector. The private sector lacked interest in public health aspects of TB treatment and trust in the public sector. The study points to two different organizations that have the potential capacities to act as mediators between the public and private sectors: international research institutions and non-governmental organizations.

- [1] Magnetic conjugate observations by Cluster and DMSP F14 satellites are used to study the field lines of auroral arc. Cluster is well above the acceleration region and observes upward keV ion beams and bipolar electric structures. The integrated potential at Cluster altitudes shows a dip that is consistent with the keV electron acceleration energy at low altitude. The earthward Poynting flux at Cluster altitudes is comparable to the electron energy flux at low altitudes. Thus, for this event the auroral acceleration can be described as a quasi-stationary potential structure with equipotential lines reaching the Cluster altitudes. The arc forms at the outer edge of the plasma sheet at a density gradient. Multiple Cluster satellite measurements allow us to study the density increase associated with the development of the arc, and to estimate the velocity of the structure. The quasi-potential structure itself may be part of an Alfven wave.
