A study on the feasibility of using pseudorandom modulation continuous-wave (PMCW) Na lidar for mesopause-region temperature and horizontal wind measurements is presented with a number of specific geometries and associated beam-telescope overlap functions, suitable for ground-based and airborne deployments. The performance of these deployment scenarios is analyzed by scaling from the received s...
Two independent wind profiles were measured every hour during Februa j 1986 with a five-beam, UHF (405 MHz) wind Profiler at Platteville, Colorado. Our analysis of the horizontal wind components over all heights for the entire month gave a standard deviation of about 1.3 m s-' for the measurement errors one can expect for three-beam Profilers in clear air. This study demonstrated that it is imp...
OBJECTIVES International donors financing the delivery of antiretroviral treatment in developing countries have recently emphasised their commitment to rigorous evaluation of antiretroviral treatment impact on population health. At the same time frame, but for different reasons, they have announced that they will shift funding from vertically structured (ie, disease-specific) interventions to h...
BACKGROUND The Ocular Hypertension Treatment Study (OHTS) has shown that topical ocular hypotensive medication is effective in delaying or preventing the onset of primary open-angle glaucoma (POAG) in individuals with elevated intraocular pressure (ocular hypertension) and no evidence of glaucomatous damage. OBJECTIVE To describe baseline demographic and clinical factors that predict which pa...
