Assessment of thruster induced contamination of critical surfaces is the important and necessary stage of International Space Station (ISS) component design. Plume contamination models aimed at the prediction of the spatial distribution of contaminant mass fluxes have been developed in the recent years for various ISS thrusters based on vacuum chamber and space flight experiments and empirical ...

Water quality data collection in shallow water areas can be a challenging task. Obstacles encountered in such environments include difficulty in covering large territories and the presence of inaccessible areas due to a variety of reasons such as a soft bottom or contamination. There is also a high probability of disturbing the test area while placing the sensors. This paper describes a NASA-fu...

Atrazine has been identified in at least 20 of the 1,636 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (HazDat 2003). However, the number of sites evaluated for atrazine is not known. The frequency for these sites within the United States can be seen in Figure 6-1. Of these sites, all 20 are located within the United States and none are lo...

Abstract Microfluidic processes are of great interest for the production nanoparticles with reproducible properties. However, in real systems, it is difficult to completely exclude incidental larger particles, which can contaminate product or clog downstream process modules. A class microfluidic filters was devised eliminating particulate contamination multistage continuous‐flow processes. To a...

Immature calf testes were found to be an unusually rich source of follitropin (FSH) receptors. Particulate fractions derived from such testes bound 32% of added biologically active radiolabeled human FSH (12”I-labeled hFSH) and had a binding capacity of 52 x lo-l4 mol/mg of protein. These values are considerably higher than those previously reported for FSH receptors in other types of beef or m...

We investigate the performance of robust estimates of multivariate location under nonstandard data contamination models such as componentwise outliers (i.e., contamination in each variable is independent from the other variables). This model brings up a possible new source of statistical error that we call “propagation of outliers.” This source of error is unusual in the sense that it is genera...

Background & Aims of the Study: Particulate matters less than 10 microns can absorb into your lungs and reacting with the moisture and enter the circulatory system directly through the airways. The aim of this study is to assess Behavior PM 10 data in different seasons and Determination effects on human health in Ahvaz city during 2013. Materials & Methods: Data Particulate matters less than 10...
