A technique for the study of evaporation from the precorneal and cornea! surfaces has been developed. Evaporation from the superficial lipid layer (SLL) has been measured to be 10.1 x 10~ Gm.cm.^secr When this lipid layer is removed, evaporation increases around fourfold. Evaporation from the dry epithelial surface occurs at a rate of 1.8 x JO" Gm.cmr^secr After the epithelium is removed, a twe...

abstract: in this research, the functionality of sweet basil seed powder (ocimum basilicum l.) on buguette bread quality and its potential application in retarding the staling process has been studied. three different concentrations of the powder (0.5%, 1% and 1.5%, w/w, flour basis) were applied. the effects of powder on the rheological properties of dough were also investigated instrumentally...

The word “antioxidant” has become increasingly popular in modern society as it gains publicity through mass media coverage of its health benefits. The dictionary definition of antioxidant is rather straightforward but a traditional annotation would define antioxidant as “a substance that opposes oxidation or inhibits reactions promoted by oxygen or peroxides, many of these substances (as the to...

Polymerizing networks of actin filaments generate force for a variety of movements in living cells, including protrusion of filopodia and lamellipodia, intra- and intercellular motility of certain bacterial and viral pathogens, and motility of endocytic vesicles and other membrane-bound organelles. During actin-based motility, coexisting populations of actin filaments exert both pushing and ret...

The main objective of this work was to increase the retarding effect of the acid dye Telon(®) Blue RR (C.I. Acid Blue 62; DyStar, Frankfurt, Germany) release on polyamide fibres dyeing by encapsulation of the dye in liposomes as an alternative to synthetic auxiliaries, in order to reduce effluent pollution. The retarding effect achieved with the use of mixed cationic liposomes of dioctadecyldim...

A fiber-optic voltage sensor based on the longitudinal Pockels effect in a Bi(12)TiO(20) crystal is described. The use of a special backreflecting prism as a phase-retarding element is shown to improve the sensitivity and temperature stability of the sensor. A comparison between the temperature properties of the glass backreflecting prism and that of a quarter-wave plate is derived. The sensor ...

Extended microscale crystal defects, including dislocations and stacking faults, can radically alter the properties of technologically important materials. Determining the atomic structure and the influence of defects on properties remains a major experimental and computational challenge. Using a newly developed simulation technique, the structure of the 1/2a <100> screw dislocation in nanoporo...
