Recent Advances in Synovial Fluid Analysis

Synovial fluid analysis is a frequently ignored examination except in suspected cases of septic conditions. It has been shown that it is an extremely valuable procedure in making rapid and accurate diagnoses in many types of joint diseases

Musculoskeletal Sarcoidosis and Rheumatoid Factor

Articular manifestations of sarcoidosis were present in 19 of our 60 patients (32%). This correlates with previously reported studies. In all of our cases but one, the articular manifestations subsided in eight weeks. This fact and the absence of hyperuricemia are in contradistinction to other studies for which we have no adequate explanation

Low cost silicon solar array project large area silicon sheet task: Silicon web process development

Growth configurations were developed which produced crystals having low residual stress levels. The properties of a 106 mm diameter round crucible were evaluated and it was found that this design had greatly enhanced temperature fluctuations arising from convection in the melt. Thermal modeling efforts were directed to developing finite element models of the 106 mm round crucible and an elongated susceptor/crucible configuration. Also, the thermal model for the heat loss modes from the dendritic web was examined for guidance in reducing the thermal stress in the web. An economic analysis was prepared to evaluate the silicon web process in relation to price goals

Silicon web process development

Thirty-five (35) furnace runs were carried out during this quarter, of which 25 produced a total of 120 web crystals. The two main thermal models for the dendritic growth process were completed and are being used to assist the design of the thermal geometry of the web growth apparatus. The first model, a finite element representation of the susceptor and crucible, was refined to give greater precision and resolution in the critical central region of the melt. The second thermal model, which describes the dissipation of the latent heat to generate thickness-velocity data, was completed. Dendritic web samples were fabricated into solar cells using a standard configuration and a standard process for a N(+) -P-P(+) configuration. The detailed engineering design was completed for a new dendritic web growth facility of greater width capability than previous facilities
