Photopolymers can be appealing materials for diffractive optical elements fabrication. In this paper, we present the recording of diffractive lenses in PVA/AA (Polyvinyl alcohol acrylamide) based photopolymers using a liquid crystal device as a master. In addition, we study the viability of using a diffusion model to simulate the lens formation in the material and to study the influence of the ...

An enzyme immunoassay for the diagnosis of syphilis (ELISA-SY) was developed with solid-phase extracts of Treponema pallidum, specimen diluent containing Reiter treponeme absorbent, and three 30-min incubations. The ELISA-SY results were determined in comparison with a standardized positive control and reported as a percentage of strong positive control. In tests with 1,005 serum samples from a...

Increasing CO2 gas emissions results in climate change by increasing air temperature and worsening environmental problems. It is necessary to control the overcome this. This research aims optimize absorption of with 0.1 M NaOH absorbent column Raschig ring stuffing material using response surface methodology (RSM). was conducted a continuous system three independent variables varying contact ti...

In this study, we report the synthesis and application of mesoporous CoFe2O4@MIL-100(Fe) hybrid magnetic nanoparticles (MNPs) for the simultaneous removal of inorganic arsenic (iAs). The hybrid adsorbent had a core-shell and mesoporous structure with an average diameter of 260 nm. The nanoscale size and mesoporous character impart a fast adsorption rate and high adsorption capacity for iAs. In ...

The addition of sachets or pads containing volatile antimicrobial agents into packages has been the most successful commercial application of antimicrobials to packaging. In this study, the effect of oregano (Origanum onites) essential oil on the extension of shelf life of overwrap packed fresh chicken drumsticks was investigated. Meat exudate absorbent pads were sprayed with 5 mL of oregano es...

A Markov process with several absorbent states is applied for analyzing a breast cancer dataset. The study examines the evolution of patients until death, and shows that two well-differentiated ways can be considered in the evolution of patients towards the death state: those who relapse and those who not. The risk groups we have considered are determined by the application of treatments radiot...

I describe a method to measure blood coagulation properties, based on the hypothesis that the distance the serum component of a clotted plasma sample moves through a suitable absorbent material should be proportional to the blood's ability to clot. A simple apparatus was constructed to test this principle, in which an absorbent strip contacts clotted plasma samples. At various times, the liquid...

Ignitable Liquid Absorbent (ILA), a commercial solid absorbent intended to assist fire scene investigators in sample location and collection, has been field tested in three separate room fires. The ability of the ILA to detect and absorb different amounts of gasoline, odorless paint thinner, and camp fuel on two different substrates after a full-scale burn was assessed against results from an a...
