Introduction: The search for life on Mars involves many potential strategies for the analysis in situ of surface samples or the analysis of returned samples in a controlled environment, in particular analyses seek evidence of tangible life and/or biomolecules. It is important to develop mineralogical standards suitable for testing the techniques that will be used for these analyses. Evaporites ...

Abstract In this paper, phosphate rock has been utilized beyond its traditional role as a raw material for fertilizer production to new potential heterogeneous base catalyst biodiesel production. The was thermally modified through calcination at 900 °C 8 hrs. One factor time experimental design used vary the operating conditions of (30–150 min), temperature (40 °C–80 °C,) concentration (1–5 wt%...

Coagulation laboratory tests are vital to the diagnosis, treatment, and management of bleeding and hypercoagulability disorders. Some laboratories, however, fail to follow voluntary practice guidelines for coagulation testing (1, 2), and inappropriate performance of coagulation tests, such as the prothrombin time (PT) test, may contribute to coagulation and bleeding complications (3, 4). A 2001...

The bias flow nitrogen washout technique for measuring the functional residual capacity in infants. M.G. Morris, P. Gustafsson, R. Tepper, M. Gappa, J. Stocks, on behalf of the ERS/ATS Task Force on Standards for Infant Respiratory Function Testing. #ERS Journals Ltd 2001. ABSTRACT: The functional residual capacity (FRC) is the most commonly measured static lung volume in infants. It is importa...

Pulmonary function tests are most useful when performed with good technique and with an accurate system. Using standard techniques in performing the tests minimizes diagnostic and therapeutic errors. This report discusses the rationale and limits of standardization and offers practical suggestions for using available standards to increase confidence in test results.

Remote sensing methods are now used to assess rockmass characteristics along transportation corridors, in mines and tunnels, and in other areas where rock falls can affect humans and infrastructure. A variety of sensor methods, primarily LiDAR and photogrammetry, have seen recent use with widespread success and state of practice acceptance. Various commercial and custom tools exist to process t...

Lightweight wheelchairs are characterized by their low cost and limited range of adjustment. Our study evaluated three different folding lightweight wheelchair models using the American National Standards Institute/Rehabilitation Engineering Society of North America (ANSI/RESNA) standards to see whether quality had improved since the previous data were reported. On the basis of reports of incre...
