We present the experimental implementation and validation of a phantom for diffuse optical imaging based on totally absorbing objects for which, in the previous paper [J. Biomed. Opt.18(6), 066014, (2013)], we have provided the basic theory. Totally absorbing objects have been manufactured as black polyvinyl chloride (PVC) cylinders and the phantom is a water dilution of intralipid-20% as the d...

To gain insight into the potential for aerosolization of viruses in wastewater systems, we investigated the partitioning of MS2 and Phi6 bacteriophages in synthetic sludge and anaerobically digested sludge from a wastewater treatment plant. We evaluated partitioning among the liquid, solids, and material surfaces of porcelain, concrete, polyvinyl chloride (PVC), and polypropylene. In all cases,...

Design and application of powder composite electrodes for electrosynthesis and electroanalysis research has been carried out. The physical characterization of electrodes was analysis using SEM, EDX and FTIR. The electrochemical stability was analysis using cyclic voltammetry. The stability of electrodes was analyzed using Atomic Absorption Spectroscopy (AAS). The powder composite electrodes wer...

Biological phantoms are commonly used on biomedical ultrasound research, but they have some limitation. We have been studying the acoustic and thermal properties of polyvinyl chloride-plastisol (PVCP) that have longer time stability. We estimated thermal conductivity in steady-state methods and specific heat with Method of Mixture. PVCP blocks were made with different graphite and PVC powders c...

In recent decades, probiotic products have been increasingly used to prevent certain gastro-intestinal and urogenital disorders, improve the general condition of body as a supplement pharmacological therapy. They are most often registered dietary supplements, less drugs in form capsules, powders, solutions. Optimization technological processes production packaging these aims maintain characteri...

The effect of temperature on fluorescence and emission anisotropy spectra of 4-cyano-N,Ndimethylaniline (CDMA) was investigated in viscous (glycerol and paraffin oil) and rigid (polyvinyl alcohol) PVA and polyvinyl chloride) PVC) media. A strong effect of temperature on the intensity of a and b emission bands was observed. It was also found that the emission anisotropy, r, does not vary in the ...

this study investigated the effect, on reactor performance and biomass retention inside the bed, of the material used to make the supports of anaerobic fixed-bed reactors. three inert supports of similar shape but made of three different materials polyvinyl chloride, polypropylene, high-density polyethylene were manufactured and used. all three supports had the same specific surface area but di...

In this paper, we synthesized a kind of bio-based plasticizer epoxidized linoleic acid cardanol ester (ELCE) from and acid. Its chemical structure was characterized with FT-IR 1H NMR. Polyvinyl chloride (PVC) blends plasticized ELCE were prepared via thermoplastic blending torque rheometer. The performance including torque, mechanical property, thermal stability, plasticizing property migration...

A simple and rapid method using HPLC was developed for the determination of tricresyl phosphate (TCP) in polyvinyl chloride (PVC) articles. A test sample was extracted with acetonitrile at 37 degrees C overnight. The extract solution diluted with an equivalent amount of water was applied to a Sep-Pak C18 cartridge, and TCP was eluted with acetonitrile-water (2:1) mixture. The eluate was analyze...
