Particulate matter filtration is a key component of crewed spacecraft cabin ventilation and life support system (LSS) architectures. The basic particulate matter filtration functional requirements as they relate to an exploration vehicle LSS architecture are presented. Particulate matter filtration concepts are reviewed and design considerations are discussed. A concept for a particulate matter...

An increase in the number of motorized vehicles has potential to air pollution, es-pecially on protocol roads, one which is Particulate matter (PM 2.5). The response tri-chomes from shade plants vehicle exhaust gases can be used as environmental biomonitor-ing. main road Seberang Ulu II District a fairly dense mobility terms Ve-hicle Volume Ratio Road Capacity (VCR). purpose this study was dete...

which had been added bovine serum albumin. The latter has been shown to aid in the preservation of Neurospora mitochondria capable of coupling oxidation to phosphorylation.4 It would seem then that the inclusion of bovine serum albumin in the medium has allowed us to isolate mitochondrial preparations capable of demonstrating substrate-independent amino acid production. Summary.-The mitochondri...

3. Applicable Pollutants: Particulate Matter (PM), including particulate matter less than or equal to 10 micrometers (μm) in aerodynamic diameter (PM10), particulate matter less than or equal to 2.5 μm in aerodynamic diameter (PM2.5), and hazardous air pollutants (HAPs) that are in particulate form, such as most metals (except mercury is the notable exception, as a significant portion of emissi...

Microbodies, designated as peroxisomes because of their enzyme complement, have been isolated from spinach leaves. After grinding leaves in 0.5 M sucrose, the peroxisomes were removed with the broken chloroplast fraction by differential centrifugation. During sucrose density gradient centrifugation, the peroxisomes banded in about 1.9 M sucrose and were separated from mitochondria and chloropla...

conclusions according to the results obtained, the largest numbers of deaths and illnesses were due to the high average pm10 concentration or an increase in the number of days of exposure to this pollutant. background particulate matters have harmful effects on human health and can intensify mortality and disease. objectives the purpose of this study was to evaluate the health impacts of partic...

This study aimed to determine the association between herbivore behavior and cues from producers. We used stream grazer Glossosoma larvae and determined their crawling direction in relation to chemical and visual cues from microalgae. The experimental treatments included control (no cue), particulate (chemical and particulate cues), and dissolved (chemical cue) cues from microalgae. The experim...

Smooth muscle cells were dissociated from normal rabbit aorta by incubating the tissue in Hanks' solution containing elastase, collagenase, and hyaluronidase. The isolated cells contained significant amounts of the following acid hydrolases: N-acetyl-beta-glucosaminidase, N-acetyl-beta-galactosaminidase, beta-galactosidase, beta-glucuronidase, alpha-mannosidase, beta-glucosidase, acid phosphata...

The distribution of backscattered intensities as described by the probability density function (PDF) of tissue-scattered light contains information that may be useful for tissue assessment and diagnosis, including characterization of its pathology. In this Letter, we examine the PDF description of the light scattering statistics in a well characterized tissue-like particulate medium using optic...

Amniotic fluid at 15-20 weeks contains high concentrations of microvillar enzymes which serve as markers for the prenatal diagnosis of cystic fibrosis. We found that these enzymes were mostly bound to amniotic fluid particulate fraction which eluted in the void volume on Sepharose 6B chromatography and precipitated in ultracentrifugation at 100,000g. Electron microscopy showed that the particul...
