the aim of the present study was to investigate the effect of addition of soymilk on physicochemical, microbial, and sensory characteristics of milk fermented with lactobacillus acidophilus. soybeans were blended 1:5 w/v with distilled water. the prepared soymilk was added to milk in combinations of 20%, 40%, and 60%. milk was used as the control. all the samples were sterilized and fermented w...

BACKGROUND AND AIM: Fluoride varnish as an extrinsic factor may cause discoloration in tooth-colored restorative materials. This research compared the impact of different fluoride varnishes on color change of a composite restorative material.METHODS: This laboratory experimental study was conducted on 40 specimens of flowable composite resin were divided into four groups based on the brand of a...

Abstract Basic Brown 16 pigment and three types of surfactants were used to prepare the cationic, nonionic, anionic basic hair dyes. White bleached dyed using dyes shampooed 10 times acidic, neutral, alkaline shampoos prepared in study. with dye resulted a lower L *, b * values K/S compared cationic nonionic results statistically significant at α = 0.05. Hair showed significantly higher Δ E ab ...

Two methods for colorimetric characterization of color scanner are proposed based on the measures of perceptual color difference error. The first method is used to minimize the total color differences between the actual and predicted color samples. The second one, which is a generalization of the existing cubic-root preprocessing technique, derives the mapping between the p’th root of scanner r...

Background: Honey is a natural product, but it can be adulterated or heat-treated, both of which damage the properties of the original product. This research was focused on the evaluation of quality parameters of some commercial honeys produced in México.  Methods: Fifteen samples of commercial honeys available in Mexican market were collected. Some physicochemical parameters were determined, ...

In our recent work with M. Rogers on resolving some Boyd’s conjectures on two-variate Mahler measures, a new analytical machinery was introduced to write the values L(E, 2) of L-series of elliptic curves as periods in the sense of Kontsevich and Zagier. Here we outline, in slightly more general settings, the novelty of our method with Rogers, and provide a simple illustrative example. Throughou...

In this paper, we propose a new projector-based display which can perform the color simulator for print industry. The proposed color simulator can change the color of print by projecting the image onto the print. A color of print can be matched to the desired color by projecting the image which is calculated to minimize the color difference between the colors of target print and current print. ...
