the effect of xanthan hydrocolloid (0.1 and 0.5% w/w of flour) on physical and sensory properties of the fresh and stored barbary bread were studied. effects of hydrocolloids on physical properties of baked bread were determined by different tests of: penetration, colorimetry (hunter values) of crust and differential scanning colorimetry (dsc). sensory evaluation also was carried out for determ...

A recently introduced optometric technique, colorimetry, enables the perceptual effects of ophthalmic tints to be evaluated subjectively, optimized, and then prescribed in tinted spectacles. The new technique is beneficial in reducing visual stress in patients with dyslexia and migraine. We describe an open trial designed to ascertain: (1) whether the colorimetry assessment, as it is now given,...

A complete software on standard colorimetry, named “Colour & Colorimetry”, has been developed for laboratory computations and didactics. This software will be part of a forthcoming book on colorimetry (ref. 1). Today, it is successfully used at the University of Parma and soon will be used in the European ERASMUS Master Program, entitled "Color in Informatics and MEdia Technology" (CIMET). The ...

objective: finding a suitable laboratory test that can diagnose schizophrenia in its early stages could be very important. according to the hypothesis of lack of noradrenalin balance in the brain, it is illustrated that the disorder severity has a negative correlation with the amount of urine noradrenalin metabolite [3-methoxy-4-hydroxy phenyl glycol (mhpg) sulfate]. in this research, instead o...

the purpose of this investigation was to develop a simple colorimetric method for creatine kinase (ck). the new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and adp, with different glyoxal compounds. hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were s...

This Report was written primarily for use as a colorimetry tutorial for any MPEG users who may feel confused by the plethora of descriptive data contained in the MPEG data-stream. It is not intended to be an exhaustive treatise on basic colorimetry or even on television colorimetry; that would require a very much larger document. There are many books on the subject, but two are of particular re...

Colorimetry, 2 edition (4) contains all the definitions of colorimetric terms, discusses CIE colorimetric practice and provides many useful tables to perform colorimetric calculations. CIE Technical Committee TC 1-48 deals at the present moment with updating this publication. The update will not change anything basic in CIE colorimetry. It will mainly get the recommendations in line with the re...
