Solid energetic composites have been used and studied in standard air environments, yet the contribution of atmospheric oxygen to reactive material combustion has not been investigated. This study experimentally examines the effect of atmospheric oxygen concentration (4% or 93% oxygen) on energy propagation of nanometric aluminum with copper oxide (Al + CuO), iron oxide (Al + Fe2O3), calcium io...

Ozone is an excellent disinfectant and can even be used to inactivate microorganisms such as protozoa which are very resistant to conventional disinfectants. Proper rate constants for the inactivation of microorganisms are only available for six species (E. coli, Bacillus subtilis spores, Rotavirus, Giardia lamblia cysts, Giardia muris cysts, Cryptosporidium parvum oocysts). The apparent activa...

Various investigators have reported on methods for the estimation of iodine in air, food, water, vegetables, tissue, and blood. Chatin (1) in 1851 used the method of Rabourdin (2) and established the presence of iodine in air. Rabourdin’s method depends on converting the iodine to potassium iodide, setting it free with nitrous acid, and extracting with carbon disulfide. Detection was possible i...

SINCE the formation of the aqueous humour depends largely upon active transport across the blood-aqueous barrier (in particular the ciliary epithelium), the rate of formation will be influenced by substances which act upon the barrier by modifying its properties or behaviour. In the present paper results are presented which deal with the actions of three different types of substance, all ofwhic...

Purpose A major problem in macular degeneration is the inability to reduce RPE and photoreceptor death. These cells die by necroptosis and apoptosis, respectively, but the upstream activator(s) of these death pathways is unknown. In this study, we use the sodium iodate (NaIO3) model of oxidative stress to test the hypothesis that activation of the Fas receptor contributes to the death of the RP...

This is the first study which assessed microplastic pollution of sea salt products from Vietnam. The results obtained 9 iodate fine table and 4 raw samples collected different regions in Vietnam showed that were present 100% salts samples. mean concentration was 787±101 items/kg 340±26 for salts, respectively. For both salt, fibers predominant type microplastic, accounted more 60% total particl...
